HAI 72A00-1 — Hardwired Load Control Module Wiring Diagram

Wiring diagram and specification sheet for the HAI (Home Automation, Inc.) 72A00-1 Hardwired Load Control Module — a relay-based load switch used to control lighting and other electrical loads as part of a whole-house automation system.

Overview

The 72A00-1 is a hardwired relay module that lets a home automation control system switch mains-voltage or low-voltage loads (lighting, motors, ballasts) on and off. It accepts a low-voltage control signal on its input and switches the load through an internal relay, with a jumper to select Normally Open (N/O) or Normally Closed (N/C) contact behavior.

Input / Output Specifications

Wiring Diagram Summary

Line (L) power feeds through a 30A breaker into the module's terminal block (W/B terminal), with Neutral (N) connected directly to the same terminal block. The control module's output drives an internal relay/switch mechanism, with two orange wires carrying the switched output to the load. A yellow jumper wire on the switch selects between Normally Open (N/O) and Normally Closed (N/C) contact configuration depending on the load being controlled.

An onboard LED illuminates when the controller output is active ("LED ON: Controller Output on"), giving a quick visual check of relay state without needing a meter.

Safety Warning

CAUTION — RISK OF ELECTRIC SHOCK: More than one disconnect may be required to fully de-energize the device before servicing. Verify all power sources feeding the module and load are switched off before opening or wiring the unit.
