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 / Class I, Division 2 and receive signals from
Zone 0, 1, 2 and Zone 20, 21 and 22 including M1 / 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
