Digital (Relay) Outputs
There are two relay outputs, both SPDT’s. The relays are rated for the following:
30 VDC @ 2 Amps
125 VAC @ 0.5 Amps
Status LEDs
The Wireless I/O Mini node has a green status LED which blinks indicating the module is running. The
status LED also indicates the signal strength between it and its module pair. In addition, there are
TX/RX LEDs to indicate radio messages to/from the module.
The status LED will blink once a second if it is not connected to another module. If the node is
connected to its paired module, it will blink a link quality code every 3 seconds.
