        Features:

        • Twenty-four integrated points combine input sensing and commanded outputs.
        • BACnet/IP Ethernet links the controller to the APOGEE Automation Level Network.
        • A 100 MHz processor runs control logic using SDRAM and flash memory.
        Siemens PXC24.2-E.A is an APOGEE PXC Compact controller with local program execution and integrated field I/O.

        The PXC24.2-E.A point mix separates input-only, universal, super-universal, analog-output, and relay-output terminals.

        BACnet/IP lets PXC24.2-E.A exchange values with peer controllers and workstations while its onboard processor continues the control sequence.

        The Siemens PXC24.2-E.A 24-Point BACnet/IP Programmable Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Integrated Point Organization

        • Universal inputs: Three UI terminals receive supported sensor or contact signals without serving as commanded outputs.
        • Universal I/O: Nine UIO points are configured so each terminal performs its assigned input or output function.
        • Super-universal I/O: Four super-universal points extend the configurable signal choices, including current-output operation.
        • Analog outputs: Three dedicated outputs provide separate 0 to 10 V DC command paths.
        • Digital outputs: Five relay circuits switch their documented AC loads independently of the low-voltage analog points.

        Automation Network Role

        • Ethernet link: The 10/100 Ethernet interface is the physical path from PXC24.2-E.A to the automation-level network.
        • Native protocol: BACnet/IP carries controller objects and commands over that Ethernet connection.
        • Peer exchange: Other field panels and workstations exchange BACnet values with the controller through the network.
        • Local execution: The PXC processor continues its stored control sequence locally while BACnet/IP carries supervisory and coordination data.

        Command Circuit Boundaries

        • Universal output: A UIO point must be configured for a supported low-voltage output before it can send a command signal.
        • Super-universal output: A super-universal point adds signal choices such as a 4 to 20 mA current command.
        • Analog output: The three dedicated analog outputs supply 0 to 10 V DC signals to their assigned field devices.
        • Digital relay: The five relay outputs switch documented AC loads and remain electrically distinct from the analog command circuits.

        Program and Data Resources

        • Processor: The 100 MHz MPC852T executes the control program and handles controller communication.
        • Working memory: Sixteen megabytes of SDRAM hold the active program state and runtime data used by the processor.
        • Flash storage: Eight megabytes of flash ROM retain the controller database and firmware resources without relying on working memory.
        • Time retention: The battery-backed clock preserves time information used by scheduled control functions during normal power interruptions.
        Description
        Siemens PXC24.2-E.A is a 24-point programmable controller in the APOGEE PXC Compact family. It executes control, monitoring, and energy-management programs locally while exchanging controller and point data with BACnet/IP automation-level partners.

        The integrated I/O of PXC24.2-E.A divides the 24 physical points among three universal inputs, nine universal I/O points, four super-universal I/O points, three analog outputs, and five digital outputs. This arrangement lets input sensing, analog command, and relay control share one controller without treating every terminal as the same signal type.

        Through its Ethernet connection, PXC24.2-E.A joins the BACnet/IP Automation Level Network and exchanges peer-to-peer data with workstations or other field panels. The controller continues running its stored program locally, so network communication carries coordination and supervisory data rather than replacing the onboard control processor.

        An external 24 V AC supply powers PXC24.2-E.A, while removable terminal blocks separate field wiring from the controller body. The processor, SDRAM, flash memory, and battery-backed clock work together to retain the control database and timing information through normal operating interruptions.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why should the point-type map be reviewed before wiring PXC24.2-E.A?
        Siemens PXC24.2-E.A has several terminal classes, so the configured signal must match a UI, UIO, super-universal, analog-output, or relay-output capability.
        Can PXC24.2-E.A continue controlling equipment if the BACnet/IP workstation is offline?
        The PXC24.2-E.A executes its control program locally, so loss of the workstation does not replace the need to diagnose network-dependent coordination and operator functions.
        What causes a BACnet point from PXC24.2-E.A to appear offline while local control still runs?
        For PXC24.2-E.A, check Ethernet link state, IP addressing, BACnet network settings, device instance configuration, and the workstation path before changing the control program.
        Why can the universal points on PXC24.2-E.A not all be treated as relay outputs?
        PXC24.2-E.A separates configurable low-voltage universal circuits from dedicated digital relay outputs, and each terminal must stay within its documented electrical function.
        What power source is required before commissioning PXC24.2-E.A?
        Siemens PXC24.2-E.A requires a 24 V AC supply within the documented tolerance, with field wiring and output circuits connected to their assigned terminal groups.
