Description
The Johnson Controls LX-PRG300-1 is an LX Series free programmable controller - a LonWorks-networked building automation controller from the Johnson Controls Facility Explorer LX range. This unit is reconditioned.
Please confirm the point configuration with us before ordering. Johnson Controls' published literature covers the LX-PRG300-11 designation, which is listed with 10 universal inputs and 8 universal outputs at 24 VAC (18 I/O total). This unit is the -1 variant. The two suffixes are very likely the same point configuration, but we have not confirmed it for the -1, so please contact us and we will read the unit.
What the LX free programmable controllers do. Johnson Controls describes them as microprocessor-based controllers designed to control various building automation systems, such as multi-zone air handling units, lighting control systems, central plant applications and power measurement applications. They use the LonWorks communication protocol, and the family is built on a similar platform with differing numbers of inputs and outputs - so the controller is chosen on point count for the plant it serves.
Published power requirements for the LX-PRG300-11: 24 VAC/DC ±15%, 50/60 Hz, Class 2, protected by a 3.0 A user-replaceable fuse; power consumption 16 VA typical plus all output loads, 38 VA maximum. Operating temperature 0 to 50°C (32 to 122°F), storage −20 to 50°C, relative humidity 0 to 90%.
"Free programmable" is the distinction that matters. Unlike an application-specific controller with a fixed built-in sequence, a freely programmable controller runs a sequence written for the job - which is what suits it to central plant and multi-zone air handling work. If you need a fixed application instead, we hold LX rooftop unit, unit ventilator and VAV box controllers as separate lines.
