Part description

Product description
The device ACT20X-HUI-SAO-S transmits analog signals from hazardous areas safely galvanically separated into non or less hazardous areas. For this purpose the input circuits are designed intrinsically safe.

Features
  • Configuration and diagnosis via FDT/DTM Software “WI-Manager”.
  • The device can be mounted in the safe area and in zone 2 / division 2 and receive signals from zone 0, 1, 2, 20, 21 and 22, as well as Class I/II/III, division 1, group A-G.
  • The active or passive signal inputs for RTD, TC, potentiometer, V and mA are completely electrically isolated.
  • The device detects automatically whether an active or passive current signal is connected.
  • As cold junction compensation for the TC signal input, either the internal cold junction compensation or for even higher accuracy an external cold junction compensation terminal is used.
  • Extended self diagnostic: Monitoring of error events (e.g. cable breakage) via status relay.
  • Front LEDs indicates operation status and malfunction.
  • 3-way galvanic isolation between input, output and power supply.
