Wiring IO module
First complete the sensor wiring. (Read 2.6)
Wire for mA input, mA output, contact input. Wiring for mA input may not be necessary according
to the specification.

Wiring mA output
FLXA402 transmits 4-20 mA analog signals with maximum load of 600 Ω to peripherals including
a control system or recorders. IO module has mA output function.
Be sure to use shielded cables for output signal cables, and connect shield to terminal 63 (or
89*).
*: When mA I/O is “-A4”, the terminal 89 is used for mA input and cannot be used for output.
Use cables of rating 30 V AC or greater.
For wiring, use shielded multi-core cables.
Screws for IO module are all M3 with washers.
