Ramp generator
2281
- Multiple functions
- Programmable from front
- 3-digit LED display
- NPN and PNP inputs
- Internal ramp time or external pulses
- Reset or preset function
Advanced features
- The user interface consists of a 3-digit display and 3 function keys in the front to change a function, ramp time or an output signal range.
Application
- To convert digital signals to a time-controlled analog signal with either internally entered up/down time or with external pulses for up/down function.
- 2-phase encoder.
- Ramp generator with internal time measurement.
- Ramp generator with external pulses.
Technical characteristics
- LED’s for up, reset and down.
- 6 digital inputs make it possible to choose reset and up/down functions as either NPN or PNP input (+24 VDC).
- Via an analog switch the up and down inputs can be switched between input filters for a pulse length > 10 ms or > 0.5 ms. The 10 ms filter is used for elimination of contact-bounce.
- Analog standard current output of 0/4...20 mA or jumper selectable 0/2...10 mA, and standard voltages of 0/0.2...1 VDC, 0/2...10 VDC or special.
- 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.
