6 ) High current output
The Relay outputs can handle 8A per common (COM) in the main units: AL2-14MR-*
(O01-6); AL2-24MR-D (O01-04). Transistor outputs are 1A/point in the extension module.
7 ) GSM Function
The
α
2 Series Controller uses GSM to send an SMS to a mobile phone or a dedicated
E-mail account via a standard service provider.
8 ) Dedicated Protocol
The
α
2 Series Controllers introduces this concept allowing the user to monitor, modify and
enter current and set values in Function Blocks from a personal computer.
9 ) Built-in EEPROM
The built in EEPROM eliminates the need for battery backed data.
10 )Supports 6 languages
The system supports the following languages: English, German, French, Italian, Spanish
and Swedish.
11 ) LCD Screen
Enhanced LCD screen size displays data more clearly and enables the
α
2 Series
Controller to display bar graphs and other new data representations.
12 )Increased Memory
The CPU memory for the
α
2 Series Controller can store 5 kbyte of programming or a
maximum of 200 function blocks.
This manual will describe front panel programming of the
α
2 Series Controllers, the powerful
function block capabilities, and the functions of the front panel keys.
