Mitsubishi PLC.
The Mitsubishi PLC contains 14 inputs and 10 outputs on the base unit with an
additional 4 input and 4 outputs on an expansion module. The power supply for the unit can be 100-
240VAC, 50/60 Hz and is internally fused for 3A. The inputs are 24VDC internally fused for 5-
7mA and supplied by the PLC. All 24VDC control wiring is blue in color and is distinguished from
the red 240VAC or 120VAC control wiring. The outputs are externally fused for 2A. Outputs 1 and
2 are dry contacts used for high side control interlock and conveyor control. Outputs 0, 3-11 & 20-
23 are relay type with 120V or 200/240 V connections.
The LED indicators on the right hand side of the Mitsubishi PLC indicate the power, run and error
status of the PLC. When power is on to the PLC and the run/stop switch is in the run position the
power and run indicators will be illuminated. A solid or flashing error light indicates a processor or
program error. The LED indicators on the upper right hand side of the PLC, indicates the input
status and LED indicators on the lower right hand side of the PLC indicate the output status. If the
input (X#) indicator is illuminated, then the PLC is receiving the input. If the output (Y#) indicator
is illuminated, then the PLC is sending the output. Use of these LED’s will be helpful in
troubleshooting the machine.
