WL-RX-900 Receiver features
1.3.1 Overview
The WL-RX-900 Receiver modules have:
Three contact closure outputs rated at 1A, 240Vac
One 0-20mA analogue output
Two digital status outputs
You can wire the digital status outputs to activate an alarm if the software finds an
error or if the communications link fails. You can also set the outputs to a ‘safe’ state if
communications are lost.
