Pepperl+Fuchs HiD2844 Manual

Switch Amplifier
Features
• 4-channel isolated barrier
• 24 V DC supply (bus powered)
• Dry contact or NAMUR inputs
• 4 passive transistor 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 a passive transistor 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 transistor 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.
