A-1-2 Basic I/O Units
z CJ1W-OD204 Transistor Output Unit (8 Points)
*1 Terminal numbers A0 to A8 and B0 to B8 are used in this manual, but they are not printed on the
Unit.
Note Although 16 I/O bits (1 word) are allocated, only 8 of these can be used for external I/O. This Unit is also
treated as a 16-point I/O Unit in the I/O tables.
Name 8-point Transistor Output Unit with Terminal Block (Sourcing Outputs)
Model CJ1W-OD204
Rated Voltage 24 VDC
Operating Load Voltage Range 20.4 to 26.4 VDC
Maximum Load Current 0.5 A/point, 4.0 A/Unit

Automatic restart after error clearance. (Refer to page A-115.)
Insulation Resistance 20 MΩ between the external terminals and the GR terminal (100 VDC)
Dielectric Strength
1,000 VAC between the external terminals and the GR terminal for
1 minute at a leakage current of 10 mA max.
Number of Circuits 8 (8 points/common, 1 circuit)
Internal Current Consumption 5 VDC, 100 mA max.
Fuse None
External Power Supply 20.4 to 26.4 VDC, 40 mA min.

Circuit Configuration
• When overcurrent is detected, the ERR indicator will light, and the cor-
responding flag in the Basic I/O Unit Information Area (A050 to A069)
will turn ON.
Terminal Connections
• When wiring, pay careful attention to the polarity of the external power
supply. The load may operate incorrectly if the polarity is reversed.
