Manual

Software
  • Head mount
  • Programmable for various input signals and measuring range
  • Configurable without Power Connected
  • Inputs
  • Resistance thermometer (PT100)
  • Thermocouple (J,K,T,E,B,R,S,N,C) 
  • mV transmitter
    Output
  • 2-wire loop-power technology, 4 to 20 mA analog output
  • Fault signal on sensor break presettable
 
The  NST-H 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 NST-H transmitter can be configured without any loop or power connected making it easy to configure in the workshop before installation.
