The new 903/904 series electronic preset counters offer many possible functions. Operation modes include quantity, lengths and position displays as well as controlling the number of revolutions (rpm) or timing functions. The 903 counter has one preset value and the 904 has two. The setting of the preset values and resetting and programming the functions is all performed using four keys. One function per key and a text menu makes operating the counter easy. Current count value and preset value can be read simultaneously. When using the units for speed and frequency counting, incoming signals can be evaluated with a factor between 0,0001 and 9,9999. Count direction, differential counting or quadrature inputs are all included options. PNP or NPN inputs can be accepted making the connection to almost all encoders possible. The counters even supply the necessary supply voltage to the sensor or encoder. Maximum count frequency is 10 kHz. By using a switch this can be limited to 30 Hz on each channel separately. Different operating modes allow up/down count of seconds, minutes and hours. In all there are 13 different time measuring evaluations. Built in a DIN sized (48 x 48 mm) IP65 housing, the counter comes complete with a set of adapter frames suitable for mounting in a standard 50 x 50 mm cut-out as well as a template for easy panel cut out. Supply voltages of 00-30 V d.c. and 90-250 V a.c. 50/60 Hz are available.
