SXWMPC24A10001 Schneider MP-C-24A Plantroom Programmable Controller 4 Relay 20 Universal Points

The SXWMPC24A10001 is a SpaceLogic MP-C plant room controller, catalogued as MP-C-24A. This freely programmable IP device offers exceptional flexibility with 24 onboard points, making it ideal for plant room applications where sensor, contact, and output requirements often vary from initial specifications.

As a BACnet IP device with Ethernet connectivity, it operates independently and can be supervised from AS-B or AS-P servers, enabling plant room control and monitoring without dedicated field bus infrastructure.

The distinction between Uc and Ub point types is critical during engineering, as these groups offer different capabilities and terminal allocations are not interchangeable. Proper engineering practice involves designing the plant sequence first, then mapping signals to terminals to ensure optimal configuration.

As a freely programmable device, installation quality depends heavily on the application program. Programs should be version controlled and backed up off the device. The controller operates as an independent BACnet device, maintaining plant operation even when supervisory servers are unavailable.

Point naming and device instances should follow site conventions to ensure future engineers can easily identify and work with the controller.

• Air Handling Units & Pump Sets: Accommodates mixed temperature inputs, status contacts, modulating outputs, and staged outputs within a single device
• Chiller & Boiler Plant Rooms: Utilizes relay outputs for pump and enable commands while universal points monitor temperatures and status
• District Heating Substations: Ensures local control continuity during network maintenance periods
• Hospitals & Laboratories: Meets requirements for free programming with UL listed hardware
• Commercial Retrofit Projects: Adapts point mix to existing field wiring, eliminating need for wiring modifications
