Pulse generator 2255

frequencyprogrammable

f/I-f/f converter Programmable f/I converter Programmable decimal divider / decimal multiplier Programmable frequency generator Relay output as option Supply voltage 24 VDC Advanced features The user programmable version has a multifunction user interface consisting of three pushbuttons and a 3-digit LED displays. Application Typical signalling devices may be pulse generators, for instance flow meters, tacho-generators or inductive sensors. The f/I function is used for frequency to current / voltage conversion. The f/f function is used for division or multiplication of pulses and as a buffer for fast pulse trains. A frequency generator function e.g. used as a time base or a clock generator. Technical characteristics 3 front LEDs, indicating f.in active input (not NPN), Dig.out (NPN or relay 1) active output and a NAMUR input error signal. Analog current output can be configured within 0...20 mA range. Voltage output range is selectable between 0...10 VDC by use of internal jumpers. Feature include input filter, contact filter and an auxiliary supply for sensor such as NAMUR and S0. Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
