2. INSTALLATION
The F2A1X Frequency to Analog module is housed in a DIN Rail mountable ABS enclosure
112 x 100 x 23 mm (4.4 x 3.9 x 1 inches). There are screw terminal connections on both
ends of the unit. The module snaps onto a standard DIN Rail by clipping the non-metallic
“hook” at the base of the module into one edge of the rail then pushing the module home
allowing the metal spring clip to secure the module. The module is removed by inserting a
screwdriver into the exposed metal tab and leveraging this tab outwards while lifting the
module away from the rail.

polarity sensitive. Connect a DC supply of 12 to 24Vdc (with a 150mA source capacity)
into the two right hand terminals ensuring that the positive wire goes to the +
terminal and the common or negative wire goes to the – terminal.
