1 F/I-f/f converter2255 Programmable f/I converter Programmable decimal divider / decimal multiplier Programmable frequency generator Relay output as option Supply voltage 24 VDC ApplicationsAdvanced featuresThe user programmable version has a multifunction userinterface consisting of three pushbuttons and a 3-digit LEDdisplays. ApplicationTypical signalling devices may be pulse generators, forinstance flow meters, tacho-generators or inductive sensors. The f/I function is used for frequency to current / voltageconversion. The f/f function is used for division or multiplication of pulsesand as a buffer for fast pulse trains. A frequency generator function used as a time base or aclock generator. Technical characteristics3 front LEDs, indicating active input (not NPN), (NPN or relay 1) active output and a NAMUR input errorsignal. Analog current output can be configured within mArange.
2 Voltage output range is selectable between VDC byuse of internal jumpers. Feature include input filter, contact filter and an auxiliarysupply for sensor such as NAMUR and S0. Mounting for a standard 11-pole socket which can be adaptedfor DIN rail or plate use with PR s 7023 adaptor and 7024mounting keying.
