TRUMETER 7922 Preset counter with 2 relay outputs
This versatile counter with prescaler can be configured for square or unidirectional inputs, single or double preset with batch preset. Reset can be automatic, manual or electronic with a sink (NPN) or source (PNP) input. The display is designed as a backlit Supertwist LCD with high readability so that it can be read from any viewing angle. The count value is shown in the main display, the preset value (or batch preset value) in the sub-display.
Programming, zeroing and preselection can be done from the front panel. When powered from the mains, there is a 12 V DC output for operating a sensor. The keys below the individual digits can be used to set the P1 or P2 preselection value (or batch preselection) on the secondary display. The red zero-setting key resets the setting value in the display to 0 or P1 (depending on programming).
