Introduction
The
α
2
Series Controllers provides supervisory control for use in the home, office, factory or
wherever you need it. The
α
2
Series Controllers offers flexible I/O control for varied
applications:
Applications
The
α
2
Series is designed to be used for automatic applications including:
-
Lighting, air-conditioning or watering control
-
Opening and shutting of gates
-
Security systems
-
Domestic systems
-
Temperature control
However, the
α
2
Series Controllers is not designed to be used in the following applications:
-
Applications where high reliabilities such as nuclear power control, railway facilities,
airline facilities, vehicles, combustion equipment and medical equipment are required.
-
Applications in life critical situations
Please contact a Mitsubishi distributor for more information.
1.1
Special Features Display messages and Function Block data
1 ) Display messages and Function Block data
The
α
2
Series can display the state of operation and the alarm on the LCD screen as a
message. The values of timers and counters can be changed in RUN mode.
-
Total characters on LCD display: 12 characters x 4 lines
-
Display items: Message, values (current or set) of timers and counters, analogue
values, etc.
2 ) Program Input
The user can program directly from the front panel or use the windows based
AL-PCS/WIN-E programming software Ver2.00. Pictorial representation of data is used to
connect function blocks. Please refer to the
α
Software Manual.
3 ) Enhancement of clock function
The weekly and daily calendar timer function allows switch inputs that set the powerful
time dependent control capabilities.
4 ) Analog input, 0-10V/0-500
The DC input type for the
α
2
Series accepts 0-10V signals with a resolution of 0-500.
5 ) High Speed Counter, max 1kHz
The
α
2
Series has two dedicated high speed counters when using AL2-4EX EI1 and EI2.
6 ) High current output
Relay output is 8A/COM in the main unit AL2-14MR-*: O01-6, AL2-24MR-D: O01-04 and
the transistor output is 1A/point in the extension module.
