Selection table:

Dimension (lengthheightdepth)	Power supply	Function	AL1	AL2	Communication interface	External power supply	Input signal
7: 727280mm with hole size 67.567.5mm; 8: 964880mm with hole size 9245mm	V0: AC 90-260V; VE: AC/DC 12-30V, or DC 24V	C: Number/length; B: Batch; P: Position control	N: No output; R: Relay; S: SSR/LOGIC	N: No output; R: Relay; S: SSR/LOGIC	C0: No communication; C2: RS232; C4: RS485	A: DC 12V/30mA; B: DC 24V/30mA; C: DC 5V	I0: Two pulse inputs (encoder); I1: INA (one input for switching input)

Digital counter up/down input modes:
Mode A: Up (addition)
INA counts up. INB is GATE function. When INB is high level (or shorted with +12V), INA input is forbidden.

Mode B: Up/down (addition or subtraction)
INA counts up. INB is count-down control function. When INB is high level, INA turns count-up into count-down.

Mode C: Up/down (addition and subtraction)
INA counts up, INB counts down.

Mode D: Up/down (for encoder)
INA signal leads INB signal (count-up). INA signal lags INB signal (count-down). It is often used for encoder or grating input.

Tips: Digital counter application in positioning and speed regulation of elevator
The leveling signal of elevator is obtained by the position sensors installed in the elevator well. When there are many floors, the number of such signals is large, and there are certain difficulties in equipment installation and maintenance. At the same time these signals take up a lot of PLC input port. If using PLC and high-speed counter for positioning, it can not only solve these problems, but also can achieve frequency control of elevator.
When the elevator is running, digital counter completes the counting work driven by the optical encoder. When the elevator car rises, digital counter counts up. When the elevator car goes down, digital counter counts down. The current value of the counter is the exact position of the car in the elevator well. In this way, the accurate positioning of the elevator is realized. This positioning method has the following functions: It realizes the floor digital display of the elevator lobby and car, determines the running direction, and determines the braking time of leveling.
