Features:1. Dual Trigger design, using special twoway driver IC design.2. Strong antijamming capability, using diode free wheeling protection.3. Relay contact portion use doublesided bold wiring for a large current, safe and reliable.4. The input and output are used 5.08mm quality terminals, more convenient for connecting wire, fit for PLC control.5. Input terminal can be arbitrarily set high or low level trigger, the control is more flexible.6. Each relay has a pull indicator, relay working status clear at a glance.7. Each relay output leads to the normally open and normally closed two sets of trigger, convenient and flexible to use.Specification:Condition: 100% Brand NewLoad: AC 250V 10A; DC30V 10AType: High Low Level TriggerChannel: 8 channelWorking Voltage: 12VSize: Approx. 133 x 55 x 19mm / 5.24 x 2.17 x 0.75in(L*W*H)Package Includes:1 x 12V 8CH Relay ModuleModule Interface:1.
