(rate of change) function Arc-Sinus function The model ALPHA-P 2.00 is a digital indicator for measurement and control of process variables with direct indication in engineering units. A full complement of standard functions include ±32000 count display, direct access to the setpoints programming. The programming software allows selection of: STRUCTURE BCD OUTPUT BOARD RS232C or RS485 OUTPUT BOARD ANALOG OUTPUT BOARD SETPOINTS OUTPUT BOARD INPUT BOARD CASE WITH FIXING CLIPS POWER FILTER CIRCUIT FRONT-PANEL COVER DISPLAY MAIN BOARD Panel-mounting 1/8 DIN case, depth 120 mm Electronics assembly : • Main board with supply power filtering card. • Input card for V, mA and potentiometer. • Display and keyboard module.

To display the peak value, press the MAX/MIN key. The second push calls up the valley value. The third push makes the display show the tare value. A falling edge at the corresponding logic inputs of the CN2 connector causes the same effects. Indicates display hold Indicates tare...

ALPHA-P Remote functions (CN2) The rear connector CN2 provides 4 user programmable optocoupled inputs that can be operated from external contacts or logic levels supplied by an electronic system. Four different functions may be then added to the functions available from the front-panel keys. Each function is associated to one of the CN2 connector pins (PIN 1, PIN 2, PIN 4 and PIN 5) and is activated by applying a falling edge or a low level pulse to the corresponding pin with respect to common (PIN 3). Each pin can be assigned one of the 28 functions listed on the following pages. DISPLAY / MEMORY...
