Installation manual
- 27 -
(4) Recommended circuit
(A) For level signal
(B) For pulse signal
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
2
(AWG 22) or larger wire.
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).
(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.
(2) External output specifications
(3) Recommended circuit
1 Each element will turn on while in ON operation or if a malfunction occurs.
2 The connection cable can be extended up to 10m (32 ft).
3 The relays, lamps, diodes and extension cables, etc, must be prepared separately on site.
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.
CN5 Lead wire Details of each terminal
No.1 Green Common (External ground)
* The operation status of DIDO controller is not output.
* Operation signal is output during an error.

Rated voltage: 12VDC, 24VDC
Power Consumption: 0.9W or less
(*1) Prepare a power supply separately according to the
relay being used (12VDC or 24VDC).
(*2) Always include a diode on both ends of the relay coil.
Important
• Be sure to use 12VDC or 24VDC for a power supply.
