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.
