Signal Conditioning & Isolation Solutions

Improve process and energy efficiency and protect equipment with signal conditioning and isolation solutions

Signal conditioning and isolation solutions allow you to schedule maintenance, cut energy use, prevent costly false shutdowns, and warn of unwanted process or instrument fault conditions. Control and monitor conditions with a single digital communication link and interface directly with your systems.

AC Power Transducers and Monitors schedule maintenance, identify inefficiencies, cut energy use, and prevent expensive damage to a load device like a motor, pump, heater, or mixer by accurately monitoring AC power use and trends.

PVT, PWT, PWV

The PVT, PWT & PWV AC Power Transducers continuously track the amount of power being consumed by an electric device or a system. Available models accept an AC input from a “load” device such as a motor, pump or heater. They provide a proportional milliamp output for determining equipment power use and operating efficiency. They can also be used to trip automatic power control equipment to initiate energy conservation measures.

Displays and Enclosures take a process input signal from a temperature, pressure, level, or flow transmitter loop and view real-time process status in rugged and hazardous field environments.

PSD

The PSD PC-Programmable Loop Display features a large integral display that shows real-time process status in mA, percent, or any designated 5-character Engineering units (EGU). The loop-powered PSD reads any 4-20mA signal and displays the information with phenomenal accuracy of ±0.012% of input scale. And because it requires less than 2.3 Volts, it won’t burden most loops.

SDY

The SDY PC-Programmable Signal Isolator/Converter with Display combines smart digital technology with a large display to deliver an accurate signal that is easily monitored in the field. The highly versatile SDY accepts a wide range of current or voltage inputs, then outputs the signal as an isolated, proportional, 4-20mA current. A flexible analog/digital hybrid, this 2-wire (loop-powered) transmitter programs in seconds to handle a wide range of signal interface applications.

R-BOX

Made of metal with a rugged clear polycarbonate cover, the R-BOX meets standards for enclosing indoor and outdoor electronics approved for use in intrinsically safe and non-incentive areas. It installs quickly and easily on a surface or pipe, or in a panel.

Functional Safety products can assist with adding a single safety loop, having a few points to isolate, or augmenting a larger Safety Instrumented System. These products are designed and built in compliance with IEC 61508.

STA

The STA Safety Trip Alarm performs as a logic solver and acts on potentially hazardous process conditions; warns of unwanted process conditions; provides emergency shutdown; or provides on/off control in Safety Instrumented Systems (SIS) and traditional alarm trip applications. The 4-wire (line/mains-powered) STA models accept a signal input from transmitters, temperature sensors and a wide array of other monitoring and control instruments.

SST

The SST is a 4-wire unit powered by 24DC, 117AC or 230AC. It is designed for applications where line/mains power is readily available, such as the back of a panel or inside of a control room. The SST Splitter takes the input from one of your process signals and creates two identical, completely isolated outputs to two separate monitoring or control devices. Additionally, the SST functions as a HART splitter that passes valuable HART data to one or both of the SST’s independent outputs.

SSX

The SSX is a 2-wire isolator, drawing power from the output side of the loop. Typically, this is from a secondary receiving device such as a DCS or PLC. Use the SSX to isolate your SIS from your basic process control system. While power for the SSX is derived from the output side of the loop, disconnection or loss of power will not affect the input loop’s signal integrity. This allows maintenance to be performed on the non-critical side of the loop.

Loop Monitors and Interfaces break out analog and discrete process, status and diagnostic signals from smart multivariable transmitters and valves, monitor critical and safety-related loops. They also prevent costly false shutdowns and warn of unwanted process or instrument fault conditions.

BULLET

The BULLET WirelessHART Adapter can be used to send process signals from a smart HART field transmitter or valve, or from a non-smart analog (4-20mA) transmitter. This includes primary, secondary, third and fourth variables from smart HART transmitters, and valve position, travel and valve output pressure from smart HART valves. It also includes diagnostic and alarm data, and custom commands from both smart transmitters and valves.

HART Concentrator System HART-to-MODBUS RTU Converter (4-Wire)

The HCS HART Concentrator System HART-to-MODBUS RTU Converter (4-Wire) allows HART transmitters and valves to interface directly with MODBUS-based monitoring and control systems.

HCS

The HCS HART Concentrator System converts a HART digital signal to a serial (RS-485 or RS-232) MODBUS RTU communication protocol. This allows transmitters and valves to interface directly with MODBUS-based monitoring and control systems.

HIM

The HIM HART Loop Interface and Monitor unlocks the full potential of new and in-place smart HART multivariable transmitters and valves. The HIM allows up to three additional analog process variable measurements from a smart device with no additional process penetrations or wiring, takes full advantage of legacy instruments and works with every Smart HART device.

I/P and P/I Converters isolate, convert, split, boost, and step down process signals so field instruments can interface directly with indicators, recorders, DCS, PLC, and PC-based SCADA systems.

IPT2

The high-performance IPT2 Current-to-Pressure (I/P) Transmitter converts a current signal to a pneumatic signal so that an electronic-based system such as a DCS, PLC, or PC can control a pneumatic actuator, valve, or damper drive. Available models accept a wide range of current inputs. The IPT2 is available in a compact, 40 mm wide aluminum housting that can be conveniently snapped onto a standard mounting rail.

IPX2

The IPX2 are 2-wire (loop-powered) I/P transmitters accept a current signal (such as 4-20mA) from a DCS, PLC or PC-based control system. They convert the current signal to a pneumatic signal (3-15psig, 0.2-1bar, 20-100kPa, etc.) to provide precise, proportional control of valves, actuators and other pneumatically controlled devices. The economical IPH2 (Type 4X) is watertight, dust-protected, and resistant to corrosion and chemicals. In addition to meeting Type 3X/4X requirements, the IPX2 can be installed in explosion proof environments.

Remote I/O eliminate expensive point-to-point wires by sending process monitoring and control signals between the field and control room on one digital communication link.

CPMS

The CPMS monitors the critical current and voltage levels of one or two transformer rectifiers used in cathodic protection systems. Each module provides four or eight, fully-isolated analog input channels and four discrete (contact closure) inputs. It “concentrates” this data onto one or multiple communication links, and transmits it long distances back to one or more host DCS, PLC or PC-based control systems.

NCS

The NET Concentrator System (NCS) is ideal for creating new monitoring and control networks. It is also perfect when you want to leave existing “legacy” sensors, analog instruments and valves in place, yet still take advantage of digital signal transmission. The NCS can be used to send just a few, or hundreds, of process signals between the field and your control system. Industrially-hardened and configurable I/O stations mount throughout a site or in dispersed locations throughout the world to provide cost-effective distributed data acquisition and control.
