1 The contact relay, DC power source, extension cable, etc., must be prepared on site.
2 The connection cable can be extended up to 10m (32 ft). Use a 0.3mm
3 Strip the extra cable near the connector, and insulate the exposed section securely with tape, etc.

2. External signal output function

* External signal output requires the external I/O adapter PAC-YG10HA (sold separately).
NOTE
* When using a PAC-YG50ECA Expansion controller, connect the external input/output adapter to the external input terminal on
the Expansion controller, not to the AG-150A.
(1) External output
When one or more air conditioners are operating, the "ON" signal will be output, if a malfunction occurs in one or more air
conditioners, the "Malfunction" signal will be output.

Important
• Be sure to use 12VDC or 24VDC for a power supply.
• Connect the power supply with correct polarity.
• Do not connect the power supply without relays
being connected to the controller. (no load)
Improper connection may result in malfunctions.
