Product Description
2.1
Function
General
This isolated barrier is used for intrinsic safety applications.
The device transfers digital signals (SN/S1N proximity sensors or approved dry contacts)
from a hazardous area to a safe area.
Lead breakage (LB) and short circuit (SC) conditions of the control circuit are continuously
monitored.
Unlike a SN/S1N series safety sensor, an approved dry contact requires a 10 k
resistor
to be placed across the contact in addition to a 1.5 k
resistor in series.
This device mounts on a HiC termination board.
HiC2853R1
The input controls one 24 V DC active voltage output and one passive transistor output
with a resistive output characteristic.
The outputs have three defined states: 1-Signal = 6.5 V voltage drop, 0-Signal = 39 k
and fault > 100 k
.
HiC2853R4
The input controls one 24 V DC active voltage output and one passive transistor output
with a resistive output characteristic.
The passive transistor output has three defined states: 1-signal = 472
, 0-signal = 1385
and fault > 100 k
.
2.2
Interfaces
The device has the following interfaces:
•
Safety relevant interfaces: input, output I, output II
•
Non-safety relevant interfaces: power supply, fault output
