About this document
ZN551 Relay Pack Installation Guide by usgl-scbd3639 is a document available to read on EtoBox.
The Relay Pack is designed to simplify wiring for the ALC ZN551 controller by providing 5 relays that correspond to the dry contact inputs on the controller. It plugs directly into the controller and provides power to both the controller and an actuator. Jumpers are used to configure whether the 6th relay responds to the analog output or passes it through to the actuator. Wiring connections are made to the controller, actuator, and controlled devices.
