1. OVERVIEW
The F2A3X Frequency to Analog DIN rail module converts frequency input into an analog
voltage (0 to 5Vdc) or current (4 to 20mAdc) output. The DC input may be isolated or non-
isolated depending on options ordered, the analog output is isolated. The input signal may
be from an external sensor (measuring RPM for example) or any source of digital signal not
exceeding 12 volts. The unit provides a pulse output which mimics the input signal and has
an optional alarm with a change over relay output.
The F2A3X is user programmed using the USB or Ethernet connection as ordered and the
PM-Remote software (included). The user can set the full scale output and input scale
factor to provide an output of mV or mA out for a given input signal as well as alarm limit
(optional).
The device is powered from 12 to 24Vdc and consumes less than 100mA and plugs onto a
standard DIN Rail. The F2A3X accepts input signals from 3 wire optical, proximity,
magnetic, infrared or laser sensors, or direct TTL or external ac inputs.
When ordering the user needs to specify either a 4 to 20 mA current output or 0 to 5 Vdc
voltage output and whether isolated outputs or alarm output is required.
