Relay Module
Opis
1-channel signal conditioner, 24 V DC supply, Logic input 19 V DC .. 26.4 V DC, Recommended connectable voltage 8 V DC .. 60 V DC, Relay contact output for energized to safe function , Line fault transparency (LFT), Diagnostic function, Up to SIL 3 acc. to IEC 61508pa. This signal conditioner provides the galvanic isolation between field circuits and control circuits. The device is a relay module that is suitable for safely switching applications of a load circuit. The device isolates load circuits up to 60 V DC and the 24 V DC control circuit. The energized to safe (ETS) function is permitted for SIL 3 applications. An internal fault or a line fault is signalized by the impedance change of the relay contact input and an additional relay contact output. A fault is signalized by LEDs and a separate collective error message output.
