This is a single channel relay module 30A with optocoupler isolation 24V supports high and low Trigger
Features:
- Relay: Uses a 30A relay — capable of handling up to 250V AC or 30V DC at 30A on the normally open contact.
- Optocoupler Isolation: Ensures safe and stable operation by isolating your control signal from the load side.
- Voltage: 24V DC.
- Black 9500 terminals: Convenient for high-current wiring
- Flexible Triggering: Choose high or low level triggering with an onboard jumper — compatible with most control signals.
- Low Trigger Current: Needs only 5mA to activate — ideal for sensors, microcontrollers, and PLCs.
- Simple Connections:
- All terminals are screw-type, clearly labeled for fast wiring:
- DC+ / DC-: Power for the relay module
- IN: Signal input
- NO / NC / COM: Relay output terminals
- Dimensions:
- Without rail: 72×40×24 mm
- With rail: 86×43×45 mm
- Mounting Ready: Includes 4 mounting holes (3.1mm dia, 44.5mm × 27.5mm spacing)
- Weight: ~46g
- Use Case Example:
- PLC automation equipment control, industrial system control, internet of things control, home intelligent control, electronic hobbyist development experiment, all kinds of circuit modification For instance, a PNP proximity sensor with a 24V output can easily drive this module.
- Note on Protection:
- While the control side is opto-isolated, if you're switching inductive loads (motors, solenoids, etc.), it’s recommended to add external arc suppression (e.g., flyback diodes, snubber circuits, or MOVs) to extend relay contact life.
