The 7922 is a 6 digit LCD programmable preset counter with prescaler, quadrature input and EEPROM data storage. Housed in an IP65 sealed DIN case, this versatile counter can be configured for quadrature or uni-directional inputs, dual preset or single preset with batch preset.
The 7922’s display is a supertwist high visibility backlit LCD which can be viewed from any angle. The count is on the main display and the preset value (or batch preset) is on the lower display, while the reset can be automatic, manual or electronic with a sink (NPN) or source (PNP) input.
All programming, reset and presetting can be carried out from the counters front panel and when powered from an AC supply, there is a 12VDC output to drive a sensor.
