SW2001-EX Datasheet, PDF (1/2 Pages) MORNSUN Science& Technology Ltd. – SW20XX-EX Isolating Switching Barrier

SW20XX-EX Isolating Switching Barrier
FEATURES
● Fitted devices: 1. NAMUR Sensors;
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.

TRANSMISSION CHARACTERISTICS
Under phase-angel control
(K1 “OFF”)
Input loop current > 2.1mA, relay output close, channel
indicator light (yellow) ON.
Input loop current < 1.2mA, relay output open, channel
indicator light (yellow) OFF.
Under inverse control
(K1”ON”)
Input loop current > 2.1mA, relay output close, channel
indicator light (yellow) OFF.
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 Input loop current < 0.05mA, open circuit alarm, channel
sensor
red indicator light ON.
When connected with common To achieve open circuit detection function, a 10KΩ resistor
contact joint switch
must be connected to the switch in parallel.
ISOLATION CHARACTERISTICS
