Predetermining Counter 7922
Description 7922
6 digit supertwist LCD programmable preset counter with prescaler, quadrature input and EEPROM data storage in
an IP65 DIN case.
This versatile counter with prescaling can be configured for quadrature or uni-directional inputs, dual preset or sin-
gle preset with batch preset. Reset can be automatic, manual or electronic with a sink (NPN) or source (PNP)
input.
The 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.
All programming, reset and presetting can be carried out from the front panel. When powered from an
AC supply,
there is a 12VDC output to drive a sensor. The key below each digit sets the P1 or P2 (or batch) preset value on
the lower display. The red reset key resets the display count to zero or P1 (according to programming). In normal
operation the colon illuminates whenever relay 1 is active. In P2 Set mode the colon illuminates whenever relay 2 is
active.
