TRANSMISSION CHARACTERISTICS

Input loop current > 2.1mA, relay output close, channel

indicator light (yellow) ON.

Under phase-angel control

(K1

“OFF”)

Input loop current < 1.2mA, relay output open, channel

indicator light (yellow) OFF.

Input loop current > 2.1mA, relay output close, channel

indicator light (yellow) OFF.

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

When

connected

with

NAMUR

sensor

Input loop current < 0.05mA, open circuit alarm, channel

red indicator light ON.

When connected with common

contact joint switch

To achieve open circuit detection function, a 10K

Ω resistor

must be connected to the switch in parallel.

ISOLATION CHARACTERISTICS

Electrical isolation

Isolation between each part (Signal input end/Signal output end/Power

source end)

Isolation strength

2.5KVDC (test for 1minute, humidity < 70%)

Surge Resist

5KV 1.2/50us (Based on IEC255-4)

2. Mechanical Joints.

● Phase-angel and inverse control setting;

● Open circuit detection setting

● Respective Isolation(2,500VDC between

Input/Output/Power source);

● Operation Temperature:-20℃-+60℃

● Reliable Performance (MTBF>1,000,000 Hours).

APPLICATIONS

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.
