Product Overview
Johnson Controls' UVM1000 Universal Valve Module lets a Venturi air valve take orders from a third-party controller. Each valve is characterized at the factory, and the module holds a linearization curve for its valve that is reached through a 0 to 10 VDC command signal. It can also span, scale and linearize the valve's feedback sensor, and it supports UVM summing, an optional wiring scheme for linking modules.
Key Features
- 0 to 10 VDC command signal input
- Linearization curve stored in the module for its associated valve, matching its position to airflow in cubic feet per minute (CFM)
- Span, scale and linearization of the valve feedback sensor
- UVM summing wiring option
- Class 2 power, internal transformer with leads tagged 24V
- Circuit board with green pluggable terminal blocks
- End panels carry a fuse holder, a DB9 connector and grommeted wire entries
- Bright metal enclosure with a thumbscrew cover
Applications
- Running laboratory Venturi air valves from a building controller that is not a Johnson Controls system
- Replacing a failed UVM1000 on an existing Venturi valve
- Keeping a spare module on hand for a lab exhaust or supply system
Frequently Asked Questions
Does it need a Johnson Controls controller?
No. It is built to let third-party controllers command Venturi valves through a 0 to 10 VDC signal.
Is a configuration cable or software included?
Not included.
What exactly am I getting?
A used UVM1000 removed from a decommissioned system, clean inside and out: the enclosure, cover, circuit board, transformer, fuse holder and wiring as photographed. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
A Venturi valve is mostly a cone and a spring until something tells it what the room needs. This box does the telling; hand it a 0 to 10 volt signal.
