Relay Module
Opis
1-channel signal conditioner, 24 V DC supply (loop powered), Logic input 20 V DC .. 26.5 V DC, non-polarized, Fail-safe relay contact output for de-energized and energized to safe function , Test pulse immunity, Up to SIL 3 acc. to IEC 61508pa. This signal conditioner is a relay module that is suitable for safely switching applications of a load circuit. The device isolates load circuits up to 230 V and the 24 V control interface. The energized to safe (ETS) function is permitted for SIL3 applications with output I. The de-energized to safe (DTS) function is permitted for SIL3 applications with output II. Additionally a dual pole switching (DPS) is possible by combination of output I and II. The relays are of diverse design, but have a common effect on the individual switch output. For checking of these relays, terminals 10, 11 and 12 can be used. The test mode will be indicated by LEDs according to NAMUR NE44. The outputs are galvanically isolated from the input. Output II is protected against contact welding by a fuse depending on the used terminal.
