7.2.4 Specifications
Features
• Configuration and monitoring are performed 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 passive signal inputs for RTD, TC and mA are made for one or two channels and completely
electrically isolated.
• The two-channel version is suitable to use as a signal splitter.
• 3-way galvanic isolation between input, output and supply.
• Front LEDs indicate operation status and malfunction.
• 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 or 2 channel 1160650000 ACT20X-CJC-HTI-S PRT 21.
• Extended self diagnostic: Monitoring of error events and cable breakage via the individual status relay.
