(1) Power Supply Terminals
Connect power supply to these terminals. Power voltage 100-240V AC or 24V DC. See page 3-16.
(2) Sensor Power Terminals (AC power type only)
For supplying power to sensors (24V DC, 250mA). These terminals can be used for supplying power to input circuits.
Use the sensor power supply only for supplying power to input devices connected to the
MicroSmart .
(3) Input Terminals
For connecting input signals from input devices such as sensors, pushbuttons, and limit switches. The input terminals
accept both sink and source DC input signals.
(4) Output Terminals
For connecting output signals to output devices such as electromechanical relays and solenoid valves. The internal out-
put relay is rated at 240V AC/2A or 30V DC/2A.
(5) Expansion Connector (24-I/O type CPU module only)
For connecting digital and analog I/O modules to the 24-I/O type CPU module.
(6) Input LED (IN)
Turns on when a corresponding input is on.
(7) Power LED (PWR)
Turns on when power is supplied to the CPU module.
(8) Run LED (RUN)
Turns on when the CPU module is executing the user program.
(9) Error LED (ERR)
Turns on when an error has occurred in the CPU module.
(10) Status LED (STAT)
The status LED can be turned on or off using the user program
to indicate a specified status.
(11) Output LED (OUT)
Turns on when a corresponding output is on.
(12) Port 1 (RS232C)
For connecting a computer to download a user program and
monitor the PLC operation on a computer using
WindLDR .
(13) Analog Potentiometer
Sets a value of 0 through 255 to a special data register. The 10- and 16-I/O types have one potentiometer. The 24-I/O
type has two potentiometers. The analog potentiometer can be used to set a preset value for an analog timer.
(14) Port 2 Connector (16- and 24-I/O type CPU modules only)
For connecting an optional RS232C or RS485 communication adapter.
(15) Cartridge Connector
For connecting an optional memory cartridge or clock cartridge.
(16) Terminal Cover
For protecting the input and output terminals. When wiring the terminals, open the covers.
(17) Hinged Lid
Open the lid to gain access to the port 1, port 2 connector, and analog potentiometer.
(18) HMI Connector Cover
Remove the HMI connector cover when using an optional HMI module.
(19) Dummy Cartridge
Remove the dummy cartridge when using an optional memory cartridge or clock cartridge.
(20) Expansion Connector Seal (24-I/O type CPU module only)
Remove the expansion connector seal when connecting a digital or analog I/O module.
