MOD-LH Series

ProVu Meter Shown in a PDA2301 Enclosure with MOD-LHRB1 Red Light / Horn and Reset Button. Meter & Enclosure Sold Separately. Assembly Required.

Precision Digital offers a wide variety of NEMA 4 and NEMA 4X enclosures that can be equipped with MOD-LH Light / Horn and Reset Button. The MOD-LH Series is available in three different light configurations. The first option is a factory ordered Light / Horn with a color of either red, green, yellow, blue, or white. The second option is a Light / Horn the user determines the light color (red, green, yellow, blue or white) by connecting the appropriate wire. The third option is a Light / Horn with red, yellow, and green layers the user can turn on independently.

The MOD-LH can be powered from the ProVu’s 200 mA transmitter power supply with enough power left over to drive most transmitters.

The light(s) and horn can be controlled independently of each other by up to eight separate relays on the ProVu meter. These relays can be programmed for automatic or manual reset action to satisfy a wide variety of audible and visual alarm applications. The light can be programmed to flash (not available on MOD-LH5CB1) or stay steady-on.

When MOD-LH is ordered, the accompanying enclosure on the order comes with the holes pre-drilled for the Light / Horn and the Reset Button and the user performs the mounting and wiring. Meter and enclosure are sold separately. The Light / Horn and the Reset Button can also be ordered as separate items and the user performs all hole-drilling, mounting and wiring as desired.

Note: The Light / Horn accessory is powered from the 200 mA transmitter power supply, so when this is installed, there is less power available for the transmitter. See Transmitter Power Supply specification for details.


There are a wide variety of ways these Light / Horn devices can be controlled by the ProVu’s two, four or eight relays to satisfy visual and audible alarm applications. Please feel free to contact tech support to discuss your particular application. The following examples illustrate some typical applications.

Control Stations for Remote Operation of Light/Horn
