5V 4-Channel Module with Optocoupler Isolation High and Low Level Trigger

1. 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. module voltage: 5V 4. each way module can be set high or low triggered by jumper 5. fault-tolerant design, even if the control line is broken, the relay will not operate 6. power indicator (green), 4 relay status indicator (red) 7. interface design humane, all interfaces can be connected directly via terminal wiring leads, very convenient 8. module size: 73 * 50 * 18mm (L * W * H) 9. has four mounting bolts holes, hole 3.1mm, 67mm * 44.5mm pitch Module interfaces: 1. DC+: positive power supply (voltage required by the relay, there 5V, 9V, 12V and 24V choice) 2. DC-: negative power connection 3. IN1-IN4: each way based on the settings, can be high or low to control the corresponding relay Relay outputs: a 12- line interface, the interface can be directly connected to all leads, user-friendly 1. NO1 - NO4: normally open relay interfaces, relay before the vacant after the pull shorted with COM 2. COM1 - COM4 Common Interface Relays 3. NC1 - NC4: normally closed relay interface relay shorted with COM ago, after the pull- vacant High and low trigger selection ends: 1. S1-S4 in order to relay 1 way-4way high and low trigger selection 2. When com with low short circuit, triggering the corresponding relay is low, while the high end of the short com high trigger
