Node address is settable from 0 to 63.
● Node address is changed when re-supplying the power to the unit.
After changing node address, must re-supply the power.
Mounting on panel
① Pull Rail Locks(standard terminal block type: 3EA, sensor connector type: 2EA)
on the rear part of a unit, there are xing screw hole.
② Place the unit on a panel to be mounted.
③ Make holes on xing screw positions.
④ Fasten the screw to x the unit tightly.
Tightening torque should be below 0.5N·m.

Caution During Use
Turn OFF the power before connecting or disconnecting expansion units.
Node addresses of connected units on network should not be duplicated. If you change a node address during
operation,unit status(MS) red LED fl ashes and it communicates with a previous node address.
Re-supply power and the changed node address is applied.
Communication speed which is set on master is set automatically. If you change the communication speed during opera-
tion, network status(NS) red LED turns ON and it does not communicate.
Re-supply power and it operates normally.
Make sure to use DeviceNet standards communication cables, and taps.
It may cause communication error if non-standards products are used.
Make sure to examine disconnection or short-circuit before connecting cables.
Avoid installing the units where severe dust exists or where corrosion may occur.
Installation environment
• It shall be used indoor.
• Altitude Max. 2,000m
• Pollution Degree 2
• Installation Category II
● 120Ω ● 1% of metallic film ● 1/4W
※Do not install terminating resistance on the unit, or it may cause network terminating problem(Impedance can be too high or
low) and trouble.
※Connect terminating resistance on the both ends of the trunk line.

Mounting on DIN rail
① Pull Rail Locks(standard terminal block type: 3EA, sensor connector type: 2EA)
on the rear part of unit.
② Place the unit on DIN rail to be mounted.
③ Press Rail Locks to x the unit tightly.
Connection of basic unit and expansion units
(standard terminal block type)
① Turn OFF the power of a Basic unit.
② Place an expansion unit to be installed next to the basic unit.
③ Connect the cable of expansion unit to the connector of a basic unit.
④ Install a connected expansion units as the right gures.
⑤ Supply the power to a Basic unit.
(Re-supply the power of a basic unit and it recognizes expansion units.)
Connection of basic unit and expansion units
(sensor connector type)
① Turn OFF the power of the basic unit.
