Pepperl+Fuchs HiD2824 Manual

Switch Amplifier
Features
• 4-channel isolated barrier
• 24 V DC supply (bus powered)
• Dry contact or NAMUR inputs
• 4 relay contact outputs
• 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 two form A normally
open relay outputs for the safe area load. The module output
changes state when the input signal changes state. The
normal output state can be reversed with the selector switches
on the side of the unit.
Line fault detection (LFD) can be selected or disabled via a
selector switch.
During an error condition, the relay reverts to its de-energized
state and the LEDs indicate the fault. A separate fault output
bus is available. The fault conditions can be monitored via a
Fault Indication Board.
This module mounts on a HiD Termination Board.
