4-channel optocoupler relay module board, high and low trigger 5V/12V/24V (24V)

Features:1.Adopts patch panel photocoupler insulation, strong driving capacity, and stable performance.Triggering current is 5mA.
2.Module operating voltage is selectable at 5V, 12V, or 24V.
3.Each module path can be triggered by a high or low level using a jumper setting.
4.Fault-tolerant design; even if the control line breaks, the relay will not trip.
5. Power indicator (green), 4-way relay status indicator (red).
Specifications:Features:
Adopts patch panel optocoupler insulation, strong driving capability, stable performance.Triggering current is 5 mA.
Module operating voltage is selectable at 5 V, 12 V, or 24 V.
Each module channel can be triggered by high or low level via a jumper setting.
Fault-tolerant design; even if the control line breaks, the relay will not move.
Power indicator (green), 4-way relay status indicator (red).
Humanized interface design; all interfaces can be directly connected via the terminal cable, very convenient.
Four mounting bolt holes are provided.
Specification:
Weight: 60g/2.1oz
Common interface load: AC 250V/10A, DC 30V/10A
Module size (L*W*H): 73*50*18.5mm/2.9*2*0.7in
Bolt hole: 3.1mm; 67*44.5 mm (spacing)
Voltage: 5V, 12V, 24V (optional)
Module Interface:
1. DC+: Connect to the positive terminal of the power supply (voltage is required for the relay; 5V, 12V, and 24V are selectable)
2. DC-: Connect to the negative terminal of the power supply.
3. IN1-IN4: Depending on the setting of each circuit, the corresponding relay can be controlled with a high or low level for activation.
Relay output terminal: With 12 interface lines, all interfaces can be directly connected to the cable, making it convenient for users to operate.
1.NO1-NO4: The relay normally opens the interface, and the relay is suspended before activation, and is connected to COM after activation.
2.Common relay interface COM1-COM4.
3.NC1-NC4: Normally closed relay interface.The relay is shorted to COM before activation and suspended after activation.
High and low level trigger selection terminal:
1. S1-S4 is the high-low level trigger selection for relays 1 to 4 channels successively;
2.Com and Low Short connections, the corresponding relay for the low-level trigger, and Com and High Short connections for the high-level trigger.
