One digital input and one SPDT relay per equal-status node, with automatic signal forwarding
Y403-11-L LoRa Auto Relay Wireless I/O, 1DI/1DO
1DI+1DO LoRa Multi-Node Wireless I/O Module
Y403-11-L uses equal-status LoRa nodes to forward switching signals automatically. Any closed input energizes all node relays for coordinated non-safety control.
Key Features
Any closed input energizes every node output, including the local relay; all inputs must open before the outputs reset
Up to 5 km per hop standard in open areas; selected 10 km configurations depend on antennas and installation
Passive dry-contact/NPN inputs, 5 A relay contacts at 277 VAC or 28 VDC, and 9–36 VDC power
For auxiliary signaling and non-safety control; relay hops add latency and the system is not certified for emergency-stop use
