PRG-1600/161/1620 switch input relay output isolation safety barrier description

The switch input isolation safety barrier accepts 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 relay output normally open/normally closed conversion setting.

PRG-1600/161/1620 switch input relay output isolation safety barrier main technical specifications
Working power supply: 20V-35Vdc
Power consumption: approximately 1.0W
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
Relay output characteristics:
Response time: 20ms
Drive capability: 250Vac/2A, 30Vdc/2A
Output function mode:
Micro toggle switch 1 and 2 settings (control channels 1 and 2 respectively)
On the "ON" side, the relay outputs "normally closed"
Set the "OFF" side, the relay output is "normally open"
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)

Alarm relay output characteristics:
