(1) Power Supply Terminals
Connect power supply to these terminals. Power voltage 24V DC. See page 3-17.
(2) I/O Terminals
For connecting input and output signals. The input terminals accept both sink and source 24V DC input signals. Tran-
sistor and relay output types are available. Transistor output type has MIL connectors and relay output type has remov-
able screw connectors.
(3) Expansion Connector
For connecting digital and analog I/O modules.
(4) Power LED (PWR)
Turns on when power is supplied to the CPU module.
(5) Run LED (RUN)
Turns on when the CPU module is executing the user program.
(6) Error LED (ERR)
Turns on when an error occurs in the CPU module.
(7) Status LED (STAT)
The status LED can be turned on or off using the user program to
indicate a specified status.
(8) Input LED (IN)
Turns on when a corresponding input is on.
(9) Output LED (Tr.OUT or Ry.OUT)
Turns on when a corresponding output is on.
(10) Analog Potentiometer
Sets a value of 0 through 255 to a special data register. All slim
type CPU modules have one potentiometer, which can be used to
set a preset value for an analog timer.
(11) Analog Voltage Input Connector
For connecting an analog voltage source of 0 through 10V DC. The
analog voltage is converted to a value of 0 through 255 and stored
to a special data register.
(12) Port 1 (RS232C)
For connecting a computer to download a user program and moni-
tor the PLC operation on a computer using
WindLDR .
(13) Cartridge Connector 1
For connecting an optional memory cartridge or clock cartridge.
(14) Cartridge Connector 2
For connecting an optional memory cartridge or clock cartridge.
(15) Communication Connector
For connecting an optional communication module or HMI base
module. Remove the connector cover before connecting a module.
(16) Hinged Lid
Open the lid to gain access to the port 1, cartridge connectors 1 and
2, analog potentiometer, and analog voltage input connector.
(17) Dummy Cartridges
Remove the dummy cartridge when using an optional memory car-
tridge or clock cartridge.
(18) Expansion Connector Seal
Remove the expansion connector seal when connecting a digital I/O or analog I/O module.
