Switch Amplifier
Features
• 1-channel isolated barrier
• 24 V DC supply (bus powered)
• Dry contact or NAMUR inputs
• Usable as signal splitter (1 input and 2 outputs)
• Relay contact output
• Fault relay contact output
• Line fault detection (LFD)
• Up to SIL2 acc. to IEC 61508
Function
This isolated barrier is used for intrinsic safety applications. It
transfers digital signals (NAMUR sensors/mechanical
contacts) from a hazardous area to a safe area.
The proximity sensor or switch controls a form A normally
open relay contact for the safe area load. The module output
changes state when the input signal changes state. The mode
of operation can be reversed with switch S1 on the side of the
unit.
One additional relay is available for the fault output. Line fault
detection (LFD) can be selected or disabled via switch S2.
During an error condition, the relay reverts to its de-energized
state and the LEDs indicate the fault. A separate output bus is
available. The fault conditions can be monitored via a Fault
Indication Board.
This module mounts on a HiC Termination Board.
