The output level is selectable for 5 or 15 Vdc logic. Isolated power for the BCD outputs is provided by an on-board supply. The tri-state, parallel BCD output option allows multiple Laureate meters and counters to be interfaced to a PLC via a single ribbon cable with mass termination connectors along its length. Only the BCD board addressed by an Enable line sends out data. All non- addressed boards remain in a high impedance inactive state.
Isolation assures freedom from ground loops.
