DZS Elec 12V 4 Channel High/Low Level Trigger with Optical Isolation Relay Module Fault Tolerant Design Load AC 0-250V/10A DC 0-30V/10A Circuit Switch Board

DZS Elec 12V 4 Channel High/Low Level Trigger with Optical Isolation Relay Module Fault Tolerant Design Load AC 0-250V/10A DC 0-30V/10A Circuit Switch Board

• Can set high or low level trigger with jumper, to meet the demand of more trigger applications.
• With patch optical isolation, strong drive ability and stable performance, the trigger current is 5mA.
• With Fault Tolerant Design, humanized terminals, even if the control line is broken, the relay will not take any action.
• With green power light, red relay status indicator light, can directly reflect the current module working condition.
• Input voltage is 12V, the max load of interface is AC 250V/10, DC 30V/10A.
