Product Description
The switch input isolation safety barrier receives contact/proximity switch inputs from the hazardous area side, and transmits them to the safe area output through the safety barrier isolation. It has the function of transistor output normally open/normally closed conversion setting.

Main technical specifications

Power consumption: approximately 1.5W
On site sensor side power supply voltage: about 8V (open circuit)
Signal input characteristics:
When the on-site input current is greater than 2.1mA, it means "ON"
When the on-site input current is less than 1.2mA, it means "OFF"
Switching hysteresis effect: 200us
Transistor output characteristics:
Response time: 20ms
Drive capability: Output current ≤ 20mA (1.2K Ω load)
Maximum current: 100mA, short-circuit current protection
Output function mode:
Dial switches 1 and 2 are set to control channels 1 and 2 respectively
On the "ON" side, the transistor outputs "E-C conduction"
On the "OFF" side, the transistor outputs "E-C cutoff"
Alarm function: (K3 is set to the "ON" side, 5 and 6 are the alarm terminals)
On site input current>7mA, short circuit alarm (SC)
On site input current<0.1mA, open circuit alarm (LB)
