The F2A1X Frequency to Analog Module converts frequency input into an
analog voltage (0 to 5 V dc) or current (4 to 20 m Adc) output. The output
is electrically isolated from the rest of the unit. The input signal may be
from an external sensor (measuring RPM for example) or any source of
digital signal not exceeding 12 volts.
The F2A1X may be factory preprogrammed or user programmed using an
oponal USB programming cable (see Opons and Accessories secon) for
any full scale output and input scale factor to provide an output of mV or
mA out for a given input signal.
The device is powered from 12 to 24 V dc and consumes less than 100 mA
and can be operated freestanding or can be mounted to a panel using the
xing wings on either end of the device. The F2A1X accepts input signals
from opcal, infrared, laser or 3-wire proximity sensors, or direct TTL or
external ac inputs. User sengs include sensor supply voltage, AC/DC
coupling and input terminaon.
When ordering the user needs to specify either a 4 to 20 mA current output
or 0 to 5 V dc voltage output and whether isolated outputs are required.
The F2A1X Frequency to Analog Module is housed in a mountable ABS
enclosure 3.2 x 1.6 x 1.2 inches [80 x 40 x 28 mm] excluding the mounng
wings. There are screw terminal connecons on both ends of the unit.

Figure 1 F2A1X Module – top view
Before mounng the unit to a panel all user opons should be set. See
Secons 3 and 4.
Power to the unit is connected to the 4-way terminal block marked DC
. Refer to Figure 2.1 above. Note that these inputs
are polarity sensive. Connect a supply of 12 to 24 V dc (with a 150 mA
source capacity) ensuring that the posive wire goes to the + terminal
and the common or negave wire goes to the – terminal.
The Analog Out terminals are the source for the voltage or current
output as ordered. These terminals are polarity sensive and are
marked + and – accordingly.
The F2A1X Frequency to Analog Module may be equipped with either
a Current Output or a Voltage Output depending on how the unit was
ordered. The Analog Out terminals are the source for the voltage or
current output. These terminals are polarity sensive and are marked
+ and – accordingly.

3
Note: The full scale output sengs must have been specied when
ordered or may be user programmed using the User Programming
Cable.
The current output is 4 to 20 mA. This output
is a current source and has a 10 V dc internal
compliance voltage. The maximum load that may
be connected is 450 ohms.
Typical connecons (shown right) are as follows:
Connecons for current out are to the terminals
marked ANALOG OUT. Connect the Posive side of
the load to the terminal marked + and the other
side of the load to the terminal marked -.
The voltage output is 0 to 5 V dc.
Connecons for voltage out are to the terminals marked ANALOG
OUT. Connect the Posive side of the load to the terminal marked
+ and the negave or common side of the load to the terminal
marked -.
The SENSOR INPUT is the input terminal used to connect an external
sensor or trigger source. There is a voltage output that may be used to
power an external sensor (5 or 12 V dc – user selectable at 75 mA max).
The system supports two wire inputs (Signal and Common) or three
wire sensors (Supply, Signal and Common). Three-wire sensors can be
open collector types – NPN or PNP, TTL output or –ve output types.

4
Connecons and their funcons are as follows:
Posive +5 or +10 V dc (user selectable) to provide power
to opcal, laser, infrared or amplied magnec sensors.
Maximum load is 75 mA dc.
SIG IN Input signal from signal sources or speed sensor. Accepts
TTL pulses or ac signals, unipolar and bipolar, from ±3 to ±12
Volts. Connect the signal wire from 3-wire sensors or the
posive side of two wire sources to this terminal. Typical input
impedance is 10 Kohms.
COM Common or Negave connecon for both signal and power
from most sensors/sources.
Refer to the User Sengs secon for input opon sengs. Typical
connecon for Monarch standard sensors is shown below:
Figure 2 Sensor Connecon Detail

There are several sengs relang to the sensor input that can be set by
the user.
The sengs are done by moving jumpers on the circuit board inside the
housing. To access these jumpers .
Then remove the two screws on the boom of the unit and remove the
base exposing the circuit board as shown below.
Figure 4 Exposed Circuit Board showing Program Jumpers
Figure 3 AC Source Connecon Detail

6
There are three jumpers as shown in Figure 4. These are:
This jumper adjusts the supply voltage to the external sensor. Can
be set as +5 V dc or +10 V dc depending on the sensor used. Factory
Default is +5 V.
This jumper sets the input terminaon. Can be set HI for 10k pull up
resistor (to sensor supply voltage) for NPN type open collector sensors
(factory default) or LO for 10k pull down resistor (to Common) for PNP
type open collector sensors or none (remove jumper altogether) high
impedance input for external terminaon.
This jumper sets the input coupling for the external signal. Can be set
to DC (default) for most digital input sources or AC for sine wave and
bidireconal sources or sensors that provide negave going pulses.
Once the jumpers have been set, replace the base and the two screws.
All the operaonal sengs of the F2A1X Frequency to Analog Module can
be set remotely using the PM Remote PC Soware and the oponal User
Programming Cable (UPC). This cable plugs into the unit via the phone jack
socket below the SENSOR INPUT terminal block as shown here and into a
USB port on the PC.
Sengs that can be programmed include
input scaling, analog output full scale and
oset, input pulse polarity and update
rate. In addion you can view real-me
data on the PC – refer to the PM Remote
manual and help screen.
