2.5.4 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 specication.
n 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.
