Programmable Isolated DIN Rail Signal Transmitter

Easy to use and Configure !

Feature: The IsignalTrans IST-D Transmitter has 1 input and 1 analog output.

Feature: Configure without power or load connected, Ideal for configuration in the workshop before installation.

Feature: All models are ISOLATED on input !

Feature: Configurable inputs and range.

Feature: Loop powered 2 wire device (10 ~ 36 Vdc)

The iSignalTrans IST-D "DIN rail" transmitter can be configured using our "iSignalTrans" software on your PC / Notebook via the URC-1020 USB interface cable that plugs into the port on the front or our dedicated handheld programmer the EzPro configurator . "iSignalWin" is our user-friendly calibration software. The latest version can be download free from our website. The transmitter can be calibrated in the workshop without connection to any wiring or power source.

  1. Calibration is done using a USB port on your PC and a special USB cable that includes an interface adaption. This cable is avaliable from us and it's code is URC-1020. or using our dedicated Hand Held Configurator the EzPro
  2. Selection of mV, V or mA inputs involves on-board dip switch selection. The input signals of the IST-D are divided into three groups. To change input signal from one group to another the DIP switch has to be set accordingly. These are ...

    1. RTD( pt100) , T/C ( J,K,T,E,B,R,S,N,C) and mV ( -60~60mV)
    2. mA ( 0~24mA)
    3. V ( -10~10V )
  3. Note on loop power source...For example, a 24Vdc power source, the Max. load of 0~20mA will be (Vpower - 12)/ 0.02 = ( 24-12 )/0.02 = 600 ohms. So, a lower power supply results in lower load capability.
