f/I-f/f Converter – 2255 is obsolete

2255 with its variations 2255B1 and 2255B2  is discontinued and updated equivalent is (5225A1 and 5225A2 without display and 4225 (4225A, 4225B, and 4225C)+4510 with display 

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 ins ce 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.

IEPSOLnical 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 s dard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
