(A separate power supply system is required for output devices.)

Short-circuits in the power supply for 
input devices are detected for each 
connector. Short-circuits in output devices 
are detected for each contact. Notification 
of any short-circuits that are detected is 
provided as part of status information. 
This enables stable operation. 

Output loads of up to 1.5 A can be controlled without 
using relays, enabling significant reductions in wiring 
costs.

DRT2-ID08C(-1): 115 mA max.

DRT2-HD16C(-1): 190 mA max. DRT2-OD08C(-1): 60 mA max.

Note

: Add the current consumption of the input devices to determine the required power supply capacity.

P/S

Maintenance is 
required for 
cylinder 23A in 
inspection line A!

High Environmental Resistance (IP67)

Smart Functions

Reduced Wiring

Detect Short-circuits to Prevent the System from Going Down

Maximum Output Load: 1.5 A

The Terminals have a watertight, oil-resistant 
construction and use materials that protect against 
spatter.

The Terminals provide smart functions that improve remote 
maintenance. A variety of information can be collected for maintenance 
systems without influencing control systems and productivity.

Three power supply systems were required: One 
each for communications, slaves, and input devices.

Power can be provided to communications, slaves, 
and input devices with just one power supply system.
