Power Supply Terminals
Connect power supply to these
terminals. Power voltage
100-240V AC or 24V DC.
Sensor Power Terminals
For supplying power to sensors (24V DC, 150mA). These
terminals have an overload sensing function.
Input Terminals
For connecting input signals from input
devices such as sensors, pushbuttons, and
limit switches. Available in DC input (sink/
source) and AC input (100-120V AC) types.
I/O Indicators
Turn on when the correspond-
ing inputs or outputs are on.
Power Indicator (POW)
Turns on when power is
supplied to MICRO
3
.
Operation Indicator (RUN)
Turns on when
MICRO
3
is running.
Error Indicator 1 (ERR1)
Turns on when an error
occurs in MICRO
3
.
Error Indicator 2 (ERR2)
Turns on when the sensor
power is overloaded.
Output Terminals
For connecting output signals to output devices such as electro-
mechanical relays and solenoid valves. Available in relay output
(240V/2A, 30V DC/2A), transistor sink output (24V DC, 0.5A),
transistor protect source output (24V DC, 0.5A) types.
Data Link Terminals
For connecting the data
link line in the expansion
link or data link system.
Pop-up Lid
Press the lid to open and gain access to the function
selector switch, analog potentiometer, and loader port.
The figures above and at right illustrate the 16-I/O type MICRO
3
base unit with DC input and relay output.
◆ For the
MICRO
3
C, see the MICRO
3
C User’s Manual. ◆
Function Selector Switch
Selects the station function in the expansion or data link system.
Analog Potentiometer
Sets the analog value for the analog timer, frequency or pulse width of
pulse outputs. The 10-I/O type has one potentiometer.
The 16- and 24-I/O types have two potentiometers; analog
potentiometer 0 on the left and analog potentiometer 1 on the right.
Loader Port
For connecting the program loader or computer.
