Power supply wiri g
Refer to "Safety Instructions" on this manual when selecting the power supply.
M12 5-pin B-code (reverse)
SW power is supplied to the sensor connected to the input block. There is a voltage drop up
to maximum 1 V inside the SI unit when SW power is supplied. Select a sensor taking this
voltage drop into consideration. If 24 V must be supplied to the sensor, it is necessary to
increase the SW power supply voltage so that the input voltage of the sensor will be 24 V with
the actual load. (Allowable SW power supply range: 19.2 V to 28.8 V)

Termi ati g resistors
Device etTM requires a terminating resistor to be installed at each end of the trunk.
The resistor requirements are:
•121 Ω
•1% metal film
•1/4 W
Terminating resistors should not be installed at the end of a drop line, only at the two
ends of trunk line.
Switch setti g
Open the protective cover, and set the switches with a small flat blade screwdriver.

FE co ectio
Connect the ground terminal to the ground. Resistance to the ground should be 100 Ω
or less.
PWR Green LED is O when power for Device etTM communication is supplied.

Red LED is flashing
Red LED is O MAC ID duplication error or BUS OFF error (serious communication error)
I/O connection time-out (minor communication error)
Note
1. The power supply should be off while setting the switches.
2. Be sure to set the switches before use.
3. After setting the switches, close the switch cover and tighten the screw to the
specified torque. (Tightening torque: 0.6 m)
∗: Output o. starts from 0, and will be assigned to the valves in order from the SI unit mounted side
∗: Manifold wiring is double wired as standard ("double wiring specification"), and the output
numbers are assigned in order from A side to B side. If the mounted valves are single solenoid
valves, the output on B side will be empty. (See Figure a)
∗: Special wiring specification with a mixed wiring of single solenoid and double solenoid can be
specified with a wiring specification sheet. This makes it possible to specify the output numbers
without empty outputs. (See Figure b)
∗: Each bit status, 0 or 1, of the data shows the O or OFF solenoid valve status (0: OFF, 1: O ),
and the output number starting from 0 will be assigned to from the lowest bit of the memory data.
∗: EX250-SD 1 disconnects the I/O connection when the solenoid valve power supply decreases or
when the input block fuse is detected to be broken (EX250-SD 1-X102 does not disconnect the I/O
connection).
