Relay Tally/GPI Outputs
Relay Tally and GPI Outputs are arranged in groups of four. Each group
has its own common connection. These commons can all be tied together,
forming one common bus for all the outputs. Alternatively, multiple
smaller commons can be constructed to interface with systems that need
isolated common connections. This common or isolated bus scheme can
extend across multiple connectors. For example, a situation may require
two isolated common buses, half of the commons form the first common
bus and the other half form the second common bus.
The example shown in
illustrates two common configurations.
The first four outputs have the common bus tied to ground. This drives a
logic system. The last outputs have the common bus tied to +12 volts. This
drives a relay tally lamp system.
