Wiring the OK Contacts

A set of isolated solid-state OK relay contacts is provided for optional

interface to an E-stop string, which controls power to the associated drives.

The OK contacts are rated for pilot duty and can drive an external 24V relay

(for example, Allen-Bradley 700-HA32Z24) whose contacts can be

incorporated into the E-Stop string as shown below.
