The WC21 P2 is a Set of two WC21 I/O Modules, that are dedicated Point to Point
transmission of Pulse generated contact closures from Meter to BAS or Data Acquisition
Input terminus point.
The WC21 P2 is a Set of two WC21 I/O Modules, that are dedicated Point to Point
transmission of Pulse generated contact closures from Meter to BAS or Data Acquisition
Input terminus point. Intervening WC21’s may be placed between meter module and
receiver to extend range if needed. The Meter Input Module accepts 1 Pulse Input and
the Receiver Module has 2 Outputs, one for the Replicated Pulse and 1 for alarm
condition, loss of RF Link and/or Low Power condition on the Meter Input Module.
