Figure 1-1. Form C Switch Simplified Schematic
Each channel is switched by opening or closing the appropriate channel
relay. Since the relays are nonlatching, the relays are all open during
power-up or power-down.
When a reset occurs, all channel commons (C) are connected to the
corresponding normally closed (NC) contacts. When a channel is closed,
the common contact (C) is connected to the normally open contact (NO).
User inputs and outputs to each channel are via the NO, NC, and C terminal
connectors on the terminal module.
