Description
The Johnson Controls LP-FX4022A-0 is an FX40 Facility Explorer supervisory controller - a Web-based Niagara supervisory controller that, unlike the FX20 and FX60, has onboard input/output built in: six universal inputs and four binary outputs.
Per the Johnson Controls FX40 ordering information, the LP-FX4022A-0 is an "FX40: includes 128 Mb RAM, 32 Mb Flash, 1 Ethernet port, 1 RS-485 port, 1 modem, 1 LONWORKS FT/TP-10 port, 6 universal inputs, 4 binary outputs, N2 driver, LONWORKS driver, BACnet IP client driver, BACnet MS/TP driver, embedded FX Workbench, embedded Web UI, 1-year software maintenance agreement".
The FX20, FX40 and FX60 are Web-based, supervisory-class controllers in the Johnson Controls Facility Explorer family, built on the Niagara framework. They sit a level above the FX field controllers - instead of driving plant directly, a supervisory controller integrates the field controllers beneath it, serves a browser-based user interface, handles scheduling, trend logging and alarming, and exports data to other systems.
Each unit carries an embedded FX Workbench and an embedded Web User Interface, so an engineer can browse and adjust the system from a standard web browser without dedicated head-end software.
The onboard I/O is what distinguishes the FX40. Johnson Controls specifies "Four form C Single-Pole, Double-Throw (SPDT) relay outputs rated for 24 VAC/DC @ 2 ampere resistive" with "One Light-Emitting Diode (LED) indicator for each relay", and "Six Universal Inputs for 10k ohm Type III (10k 4A1-International) Thermistor, 4/20 mA current loop, 0 to 10 volt, or dry contact" through a 12-bit A/D converter. Input accuracy is "in the range of ±1% of span, characteristic curve is customizable" for thermistors, and "±2% of span, without user calibration" for 0-10 volt or 4/20 mA. This lets one device supervise a system and control a small amount of plant directly.
The FX40 also ships with a notably broad driver set as standard - N2, LONWORKS, BACnet IP client, BACnet MS/TP - and a dedicated LONWORKS FT/TP-10 port, so it can bridge protocols without additional licences.
Please note this is a legacy supervisory platform. Johnson Controls states that "The FX20, FX40, FX60 are all no longer available to order and should be replaced with an FX80", and that "The FX30, FX60E, and FX70 have been discontinued and while they are still available to order, they are now at the end-of-life stage." Johnson Controls also cautions that "You cannot upgrade older supervisory controllers, such as the FX70 and FX60s, to any FX software release later than 14.4." That makes these units suitable for maintaining, extending or repairing an existing FX installation rather than for a new-build project, and it is precisely why surplus stock matters - a site running an FX supervisor cannot buy one new.
