3.3 Wiring of Each Terminal
Prior to conducting wiring, always check the polarity of each terminal.
The terminal nameplate of this instrument and its descriptions are shown in the following.
Power supply
Connect the power to terminal numbers 1 and 2.
The power supply types must be specified when ordering. Power supply voltage for the controller must be within
the range shown below for the controller to satisfy the control accuracy in the specifications.
Power supply type
Power consumption
90 to 264 V AC [Including power supply voltage variation]
(Rating 100 to 240 V AC), 50/60 Hz
HA430: 16.5 VA max. (at 100 V AC), 22.5 VA max. (at 240 V AC)
HA930: 17.5 VA max. (at 100 V AC), 24.0 VA max. (at 240 V AC)
21.6 to 26.4 V AC [Including power supply voltage variation]
(Rating 24 V AC), 50/60 Hz
HA430: 15.0 VA max. (at 24 V AC)
HA930: 16.0 VA max. (at 24 V AC)
21.6 to 26.4 V DC [Including power supply voltage variation]
(Rating 24 V DC)
HA430: 430 mA max. (at 24 V DC)
HA930: 470 mA max. (at 24 V DC)
If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.
Power supply wiring must be twisted and have a low voltage drop.
This instrument is not provided with an overcurrent protection device. For safety install an overcurrent
protection device (such as a fuse) with adequate breaking capacity close to the instrument.
Fuse type: Time-lag fuse (Approved fuse according IEC 60127-2 and/or UL 248-14)
Fuse rating: Rated current: 1.0 A
For an instrument with 24 V power supply input, supply power from a “SELV” circuit defined as IEC 60950-1.
A suitable power supply should be considered in end-use equipment. The power supply must be in compliance
with a limited-energy circuits (maximum available current of 8 A).
