mal shutdown, so when a Power Supply Unit with a low-capacity rating or
instantaneous shutoff overcurrent protection is used, the load short-circuit
may not be detected. Always use a Power Supply Unit with a rating of 50
W or higher if it uses dropping overcurrent protection characteristic. Always
use a Power Supply Unit with a rating of 150 W or higher if it uses intermit-
tent overcurrent protection. The current limiter will protect the transistor
even if short-circuit detection is disabled.
Wiring I/O Connect the I/O wiring to the Environment-resistive Terminal with the XS2-
series Round Waterproof Connectors listed in the following table.
Compatible Connectors
Sensors that are pre-wired with a connector can be connected directly.
Refer to the catalog or manual for details on the device's pin arrangements
before connecting any device.
Note Refer to the OMRON Sensors Catalog (X42) for details on Sensor Connec-
tions and Round Waterproof Connectors (Sensor I/O Connectors).
Use one of the following OMRON Y-joints when connecting a DRT2-HD16C(-
1), DRT2-HD16CL(-1), or DRT2-MD16CL(-1) Environment-resistive Terminal
with 16 inputs to sensors or limit switches, except when the sensor has diag-
nostic output.
Note The XS2G Connector Plug for Custom Cable Assembly (L-shaped type) and
XS2W-series L-shaped plug type cannot be connected to a Y-joint Connector,
because these connectors will cause interference with any Connectors
located beside them.
