1-Channel Optocoupler Relay Module Board, 12V High and Low Trigger

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.
