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

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 isolation, strong driving capability, stable performance.Triggering current is 5 mA.
Module operating voltage is selectable at 5 V, 12 V, or 24 V.
Each channel of the module 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 operate.
Power indicator (green), 4-way relay status indicator (red).
User-friendly 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 to be activated.
Relay output terminal: With 12 interface lines, all interfaces can be directly connected to the lead, convenient for users.
1.NO1--NO4: The relay normally opens the interface, and the relay is suspended before being activated, and is connected to COM after being activated.
2.Common relay interface COM1--COM4.
3.NC1--NC4: Normally closed relay interface. The relay is short-circuited with COM before being activated and suspended after being activated.
High and low level trigger selection terminal:
1. S1-S4 is the high-low level trigger selection for relay channels 1-4 successively;
2. Command and short-circuit connection low, the corresponding relay for the low-level trigger; COM and short-circuit connection high for the high-level trigger.
