RS-485

Software
  • Both channels must be set to same input type
  • Programmable for various input signals and measuring ranges.
  • Configurable without Power Connected. 
  • Din Rail Mount 
  • Inputs : User configurable for 
  • Resistance thermometer (PT100 / RTD)
    Thermocouple (J,K,T,E,B,R,S,N,C) 
    Also available for Voltage, Current and mV
  • The unique Math function : 

  • PV1 : Input 1 ; PV2 : Input 2
    A,B,C:Constant Factors are set by user

  • Outputs : 3 models are available
    1. ISC-S : Single Analog Output : 4~20 mA、0~10VDC …
    2. ISC-D : Dual Analog Outputs : 4~20 mA、0~10VDC …
    3. ISC-C : One Analog Output (OUT1) 4~20 mA、0~10VDC … with RS485 Com port : MODBUS-RTU (OUT2)
  • High accuracy in total ambient temperature range. 
  • Sensor break fault signal level pre-setable.
 
The Din Rail converter is user configurable using our software on your PC/notebook . The easy to use 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 ISC converter can be configured without any loop or power connected making it easy to configure in the workshop before installation.
