Signal Isolators

 

A range of isolators for standard, plant based, analog current and voltage signals.


ITX Plus

 

Universal, Loop Powered, Isolated, Signal Converter


This compact new signal conditioner provides complete electrical isolation and is ideal for control system applications with a mix of inputs. The ITXPlus can measure, filter and isolate different input parameters, then convert them into an industry standard 4-20mA output. With this unique capability and slim profile, ITXPlus offers savings on both I/O wiring and panel space.

Features:

  • Auxiliary Powered (12-60Vdc) Universal Input

  • Converts, filters and isolates most common signals and sensor types

  • Fully isolated

  • Loop powered

  • PC Programmable

  • Cost effective & Compact

  • Rail mount or head mount versions

  • Automatic CJC for thermocouple inputs

  • Automatic lead length compensation for RTD inputs

  • Sensor burnout detection

  • Preset and user-defined linearization

With a width of only 12.5 mm, the ITXPlus has a compact and space saving design and industry-leading features and functionality. It is DIN-rail mountable and cULus approved.

 


WavePak

 

DC/DC Current/Voltage Signal Isolator/Converters


The WavePak DC/DC signal isolator/converter is a DIN rail mount device that accepts analog voltage or current signals from field devices and provides an isolated voltage or current output.

This 4 wire DC input isolator provides 3-way isolation for any standard DC milliamp and voltage signal, with better than ±0.1% accuracy (typically ±0.05%), for simple elimination of ground loops and signal conversion where auxiliary power is available.

Features:

  • Auxiliary Powered (12-60Vdc)

  • 24Vdc power for loop powered input devices

  • Test points for Input and Output current monitoring

  • Simple secure calibration method

  • Calibration allows for input to output scaling and reverse action

  • LED status indication

  • Complete Input to Output to Power Supply Isolation

  • Compact 12.5mm wide housing

The WavePak DC/DC is cULus Listed, CE Approved and complies with the RoHS directive for hazardous materials reduction.

 


TWI Series

 

Loop Powered Isolators for 4-20mA loops. Available in single and dual channel units.


The TWI series of output loop powered isolators (also called isolated two wire transmitters) eliminate the interference that would otherwise result from differences in ground potential or connection method in 4-20mA loops.

They are available as single or dual channel units. Typically TWI isolators are used as:

  • Isolators - to eliminate faulty readings caused by ground loops, electrical interference and motor noise.

  • Signal Splitters - to produce two independent isolated 4-20mA outputs from one input. Use the TWI-2 for this application by connecting the two 4-20mA inputs in series. The outputs can go to completely separate devices such as control systems, PLCs, indicators, controllers and data loggers.

  • Signal Repeaters - to boost signals for increased transmission distance or allow additional devices to be connected to the loop.

Technical Data


The electronic subassembly is housed in a rugged powder coated aluminum enclosure which clips onto both DIN and G rail. Wiring connections are by plug-in connectors on the front of the instrument.

 

Features:

  • Output Loop Powered Isolators

  • Single and Dual Channel versions

  • Accurate, stable and repeatable

  • High C.M.R.R.

  • Independent Zero and Span controls for each channel

  • 600 ohms output drive capability at 24Vdc

  • No internal adjustments needed

 

 

The TWI-1 and TWI-2 are cULus Listed, CE Approved and comply with the RoHS directive for hazardous materials reduction.

 

 


SFI / DFI

 

Single and Dual Channel, Auxiliary Powered Isolators


The SFI is a single channel, auxiliary powered, isolator for analogue current/voltage signals. The DFI combines two isolators which can be used separately or as a signal splitter. The outputs have a high drive capability, which is ideal for signal booster applications.
 

The standard package has a single 24Vdc output to drive a loop powered transmitter as input. A second power supply (for DFI channel two) is also available as an option. The housing is a rugged powder coated aluminum enclosure which clips onto both DIN and G rail. Wiring connections are by plug-in connectors on the front of the instrument.
