Switch Amplifier
Description
2-channel signal conditioner, 24 V DC supply (Power Rail), Dry contact or NAMUR inputs, Usable as signal splitter (1 input and 2 outputs), 2 x 2 relay contact outputs with AND logic, Line fault detection (LFD), Reversible mode of operation, Up to SIL 2 acc. to IEC 61508/IEC 61511pa. This signal conditioner transfers digital signals (NAMUR sensors/mechanical contacts). Each sensor or switch controls two form A normally open relay contacts. The normal output state can be reversed using switches S1 and S2. Switch S3 is used to enable or disable line fault detection of the field circuit. During an error condition, the relays revert to their de-energized state and the LEDs indicate the fault according to NAMUR NE44. A unique collective error messaging feature is available when used with the Power Rail system.
