1. General Introduction
Pepperl + Fuchs HiC2877 1-channel Isolated Barrier for SDV541 is used for intrinsic safety applications, which supplies power to solenoids, LEDs, and audible alarms, located in a hazardous area. It is controlled with a loop-powered control signal, switch contact, transistor, or logic signal.
At full load, 11.2 V at 40 mA (with 55 mA current limit) is available for the hazardous area application. Line fault detection of the field circuit is
indicated by a red LED and an output on the fault bus. This device mounts on a HiC Termination Board.
2. Features
• 1-channel isolated barrier
• 24 V DC supply (bus or loop powered)
• Output 40 mA at 11.2 V DC, 55 mA current limit
• Contact or logic control input
