Switch Amplifier
Description
This signal conditioner provides the galvanic isolation between field circuits and control circuits. 1-channel signal conditioner, 24 V DC supply (Power Rail), Dry contact or NAMUR input, 2 active transistor outputs, Usable as signal splitter (1 input and 2 outputs), Reversible mode of operation, Line fault detection (LFD), Housing width 12.5 mm, Up to SIL 2 acc. to IEC 61508pa. The device transfers digital signals (NAMUR sensors or dry contacts) from the field to the control system. The input controls two active transistor outputs. Via switches the mode of operation can be reversed and the line fault detection can be switched off. Via switch the function of the second output can be defined as a signal output or an error output. A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
