Isolators

Introduction
ZEUS presents Isolators, IST-D (iSignalTrans) is user configurable using our iSignalwin software on your PC/notebook or our dedicated handheld programmer. The easy to use iSignalwin software is available free from your supplier or can be downloaded from our web site and should be used in conjunction with the URC-1020 USB cable which incorporates an interface converter necessary for communications. The IST-D transmitter can be configured without any loop or power connected making it easy to configure in the workshop before installation.

Feature
  1. Programmable for various input signals and measuring ranges.
  2. Configurable without Loop or Power Connected.
  3. Din Rail Mount.

Inputs
  1. Resistance thermometer (PT100 / RTD)
  2. Thermocouple (J,K,T,E,B,R,S,N,C)
  3. Also available for Voltage, Current and mV

Output
  1. 2-wire loop-power technology, 4 to 20 mA or 20 to 4 mA analog output.
  2. High accuracy in total ambient temperature range.
  3. Sensor break fault signal level pre-setable.
