Trumeter 7922 & 7932 Programmable Preset Counters

Trumeter 7922 and 7932 Programmable Preset Counters are versatile LCD counters with a prescaler, configurable for quadrature or uni-directional inputs and dual- or single-presets. The counters are housed in an IP65-sealed DIN case with a supertwist LCD display with a yellow/green LED backlight. All programming, reset, and presetting can be completed via the menu-driven display on the front panel. Trumeter 7922 and 7932 Programmable Preset Counters operate from 85VAC to 265VAC with opto-isolated inputs. The counters' output can be set to latch or pulse with programmable pulse duration. The 7922 and 7932 series feature a programmable decimal point up to three places and a 40-year data retention with no power.
