Technical Parameter
1) Supply voltage: 24VDC
2) Binary open-collector output
OC (open-collector) outputs drive capability with maximum allowable operating voltage 30VDC and
maximum allowable current 20mADC; so when the output terminal is active low, the maximum allowable
sucked current is 20mA.
Connection of Binary Output and External Circuit
The connection of solid-state relay and binary output is shown in Fig. 2-6.
