8 channel relay module 5V/12V/24V high and low level trigger relay control with optocoupler for PLC automation equipment control

Each channel can be individually switched high and low level trigger

First, the module description: 1, the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V / 10A, DC 30V / 10A; 2, using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA; 3, the working voltage: 5V,12V,24V 4, each channel relay can be set high or low-level triggered by jumper; 5, fault-tolerant design, even if the control line is broken, the relay will not operate; 6, the power indicator (green), 8 relay status indicator (red) 7, user-friendly interface design, all interfaces are available through the wiring terminal direct connection leads, very convenient 8, module size: 141.5mm * 50mm * 18.5mm (L * W * H) 9 with four mounting bolts holes, hole 3.1mm, spacing 136mm * 44.5mm  

Two module interface: 1, DC +: positive power supply (voltage relay according to requirements, 5V.9V.12V and 24V selection) 2, DC-: negative one 3, IN1-IN8: According to the settings for each channel, can be high or low level control of the corresponding relay  

Relay output: 24 line interface, all interfaces can connect directly leads, user-friendly 1, NO1 - NO8: normally open relay interfaces, relay before hanging, pull back with COM 2, COM1 - COM8: Relay Common Interface 3, NC1 - NC8: normally closed relay interfaces, relay before with COM, pull vacant post High and low end of the trigger selection: 1.S1-S8 relay 1 followed by road -8 path of high and low trigger selection; 2, com and low short, trigger the corresponding relay is low, and high when com shorted high level trigger
