Specifications
- Normally open and Normally closed.
- High-level trigger or low-Level trigger selection by a jumper.
- Optocoupler isolation.
- Terminal blocks for both input and output.
- Two LED indicators: power (green LED), the relay status (red LED).
- Fault-tolerant design, even if the control line is broken, the relay will not operate.
- Control voltage : 24V.
- Trigger current: 3mA ~ 5mA.
- Maximum load: AC 250V/10A, DC 30V/10A
- Dimension: 50mm x 26mm x 18.5mm (Lx Wx H).
Input Interface
- DC+ : Connect the positive pole of the power supply.
- DC- : Connected the negative pole of the power supply.
- IN: Signal trigger input ( high or low level signal selected via a jumper).
Output Interface
- NO: The normally open interface.
- NC: The normally closed interface.
- COM: The common interface for both normally open and normally closed.
High/Low level Trigger Selection Jumper:
- If the jumper is placed between COM and L, the relay uses LOW level trigger.
- If the jumper is placed between COM and H, the relay uses HIGH level trigger.
How it works
High Level Trigger:
- When IN is LOW level signal, the NO does not connect with COM and the NC connects with COM.
- When IN is HIGH level signal, the NO connects with COM and the NC does not connect with COM.
Low Level Trigger:
- When IN is LOW level signal, the NO connects with COM and the NC does not connect with COM.
- When IN is HIGH level signal, the NO does not connect with COM and the NC connects with COM.
