Control Relay

The PID module occupies a maximum of 32 internal relays (minimum 8 internal relays) per module. The

occupied number of internal relays varies between the fixed value control mode and program control mode.

When both CH0 and CH1 are in fixed value control mode, 8 internal relays are occupied. When either CH0 or

CH1 is in program control mode, 32 internal relays are occupied.

Internal Relay Allocation

When both CH0 and CH1 are in fixed value control mode, the following 8 internal relays are allocated:
