APPLICATIONS
Power consumption
About 2.0W (with relay output OFF)
LED light (green) ON when operating
This Isolation Switching Barrier can detect
switch or approach switch’s status in locations
where hazardous exists; isolate, transmit and
output it to safe area. Input and output can be set
to inverse control. Approach switch open circuit
detection function. Isolation between Input/
Output/Power source.

Under inverse control
(K1”ON”)
Input loop current < 1.2mA, relay output open, channel
indicator light (yellow) ON.
Open detection function
Function when K3 is OFF
Input loop current < 0.05mA, open circuit alarm, channel
red indicator light ON.
When connected with NAMUR
sensor
When connected with common To achieve open circuit detection function, a 10KΩ resistor
contact joint switch
must be connected to the switch in parallel.
