• Power Supply selection
A UL approved direct current (DC) power supply should be used with this
product, as follows:
1. A limited voltage / current supply in accordance with UL508.
A circuit from which power is supplied by the secondary coil of a
transformer according to the following:
Maximum voltage (no load) : Less than 30Vrms (42.4V peak)
Maximum current : (1) Less than 8A (including when short circuited)
(2) Limited by circuit protection (such as a fuse)
with the following rating.
2. A Class 2 power supply unit in accordance with UL1310, or a power
supply circuit of maximum 30Vrms (42.4V peak) or less, using a
Class 2 transformer in accordance with UL1585 as power source.

• Input connector
To connect the sensors.
• Communication connector
To send and receive communication signals through DeviceNet line.
• Output equipment connector
To connect the output equipment such as a solenoid valve.
• ower supply connector for output equipment
To supply power to the output equipment such as a solenoid valve.
• Indication and address setting panel
To provide LED's to indicate the condition of the unit and the setting of
address, Hold / Clear functions and auto reset functions.
• Fuse
In the power supply for the sensor SI unit and output equipment, if an
over current flows because of short circuit etc., the power supply will be
disconnected by the fuse.
In this case, the user must fix the cause of the short circuit before
exchanging the fuse.
In extreme conditions, there is a possibility of
serious injury or loss of life.
WARNING If instructions are not followed there is a
possibility of serious injury or loss of life.
