7.4.4 Specifications
Features
 Configuration and monitoring 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.
 The cold junction compensation for TC-signal inputs is either the internal cold junction compensation, or for
higher accuracy is an external cold junction compensation terminal available –- 1 channel 1160640000
ACT20X-CJC-HTI-S PRT 11.
 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.
