Each channel is switched by opening or closing the appropriate channel
relay. Since the relays are latching, the relay remains in the last state during
power-up or power-down. When a reset occurs, all channel commons (C)
are connected to the corresponding normally closed (NC) contacts. User
inputs/outputs to each channel are via the NO, NC, and C terminal
connectors on the terminal module.
