LLD-M13

I/O module that converts the main controller’s GPIO (TTL/CMOS) signals into digital signals. Multiple C-type relays allow direct power switch control, and the digital inputs support both source and sink modes — for general switch status or for detection through connected sensors.

9ch 3.3 V CMOS GPIO control points (2.54 mm 20-pin header, connects to the main controller)
- 4ch digital output (DO): relay switch, N.C. / N.O. / COM
- 5ch digital input (DI): 4ch dry contact and 1ch wet contact, 2000 Vrms optical isolation, 5~24 V DC wet contact input
Working voltage 9~24 V DC, or 3.3 V / 5 V from the GPIO header, selected by slide switch
Size 103 × 97 × 15 mm
Can be applied to equipment power, general switch control or status monitoring
