Description
This 3 channel relay module is designed for automated control circuits, using a small current to switch a larger current. It supports standard RTU protocol over an RS485 interface and also offers TTL serial control, with an 8 bit MCU and RS485 communication chip for stable data exchange. It provides 3 channel input signal detection and 3 channel relay output. Powered by DC 5-32V low voltage supply (not mains powered). Baud rate options are 4800/9600/19200, default 9600bps. Device address range is 1-255, default 255. Both settings support power off memory. PCB construction.
