Overview
The PDA3400 series of internally mounted plastic NEMA 4X enclosures for 1/8 DIN Digital Panel Meters and 1/4 DIN PID Controllers provide a convenient way to mount one, two or three Precision Digital meters to walls and other vertical structures. The PDA3400 series enclosures provide a greater degree of protection than other Precision Digital enclosures because the meters are mounted behind a clear polycarbonate cover. These enclosures also have room for a light / horn accessory. They also come pre-cut with 1/8 DIN or 1/4 DIN cutouts or they can be ordered with no cutouts / front plate. Mounting hardware is provided. The cover is secured with four screws. Optional pipe mounting kits are available for mounting the enclosures to 2" pipes. Enclosures, meters and accessories are ordered and packaged separately.
Wall Mounting
The PDA3400 enclosures include four mounting flanges and four screws. Using the included screws and a Phillips head screwdriver simply assemble each flange in the four threaded screw holes on the back of the enclosure as shown in the example below.

Accessories
PDA3400 Series Enclosure with Light / Horn
PDA3407 Enclosure Shown with a ProVu Meter and MOD-LH Light / Horn and Reset Button. Meter & MOD-LH Sold Separately. Assembly Required.
Light / Horn Accessories
Precision Digital offers a Light / Horn that can be mounted to the PDA3407 and PDA3408 by the user. This Light / Horn can be wired to flash or stay steady on and the horn is rated at 85 dB. The light and horn can be controlled independently of each other via separate relays on the meter such that the horn can be programmed to silence via a button mounted to the enclosure and the light can be programmed to stay on until the alarm clears.
The light / horn and reset button are all rated NEMA 4X or IP65. The following table illustrates a typical way the Light / Horn accessory can be wired and programmed using the four relays on the ProVu meter:
| Relay # | Connected to | Typical reset method (user selectable) |
| 1 | Flashing Light(1) | Reset automatically after alarm clears |
| 2 | Horn | Silence with Reset Button at any time |
| 3 | User Device | As user desires |
| 4 | User Device | As user desires |
1. Light can be wired to flash or stay steady on
Notes:
- The Light / Horn accessory is powered from the 200 mA transmitter power supply; so when it is installed, there is less power available for the transmitter. See MOD-LH and MOD-LHX2 Series manuals for details.
- See MOD-LHX2 manual for typical wiring diagrams using the Trident X2 meter, which has a capacity of only two relays.
MOD-LH & MOD-LHX2 Light / Horn Accessories
When these are ordered, the enclosure comes pre-drilled with holes for the Light / Horn and Reset Button to be installed by user. Meter and enclosure are sold separately. The Light / Horn hole is in the back left corner of the enclosure and the Reset button is centered on the side of the enclosure about an inch off the bottom. For mounting in different locations, order items separately and drill holes and mount as desired. Other light and button colors are available.
