List of BMS Components & Suppliers
A walkthrough of every part you will find inside a BMS control panel and on the field network around it. Each entry lists the role, example products by manufacturer, and reputable European suppliers — useful for spec writers, panel builders and procurement teams.
Components (15)
Programmable BMS Controller

Modulating Damper / Valve Actuator
Field Devices — Actuators0-10 V, 4-20 mA, BACnet or Modbus actuators driving control valves, dampers and VAV boxes.
Examples: Belimo NM24A-MOD, Siemens GDB161, Schneider M800-SR, Honeywell ML6420.
Variable Speed Drive (VSD / VFD)
Power DevicesFrequency inverter for fans and pumps, controlled over BACnet/IP, BACnet MS/TP or Modbus RTU/TCP.
Examples: ABB ACH580, Danfoss FC-102, Schneider Altivar, Vacon 100 HVAC, Yaskawa Z1000.
Energy Meter
MeteringClass 1 / Class 0.5S electrical meters and ultrasonic / mechanical heat meters with BACnet, Modbus or M-Bus output.
Examples: Iskra MT174, Carlo Gavazzi EM340, Kamstrup Multical 403, Sontex Supercal 5, ABB B23.
Relay & Contactor
Power DevicesInterposing relays and motor contactors used to switch plant from BMS digital outputs.
Examples: Finder 40 series, Schneider RXM, Phoenix Contact PLC-RSC, ABB AF series.
UPS / Power Supply
Power Devices24 V DC SMPS for controllers and field devices, plus mains UPS for critical head-ends and JACEs.
Examples: Phoenix Contact QUINT, Siemens SITOP, Mean Well DR series, APC Smart-UPS.
Industrial Network Switch
NetworkingManaged industrial Ethernet switches for the OT network — VLAN, QoS, IGMP snooping for BACnet/IP.
Examples: Cisco IE-3300, Hirschmann RS20, Moxa EDS-G508E, Stratix 5700.
Enclosure & Wiring
EnclosuresForm-2 and Form-4 panel enclosures, DIN rail, terminal blocks, ferruled wiring and labelling.
Examples: Rittal AX/KX, Schneider Spacial, Wago 2002, Phoenix UT-series, Weidmüller Klippon.
How a BMS Panel is Assembled
A BMS panel is a Form-2 or Form-4 enclosure that takes a single mains feed, drops it through fused isolation, runs a 24 V DC SMPS for controllers and sensors, and exposes Ethernet for the head-end and field-bus terminals (typically MS/TP or Modbus RTU) for outstations.
Inside, you'll typically find: one supervisory controller (or a JACE if vendor-neutral), one or more application controllers per plant item, interposing relays for digital outputs to plant, transducers for analogue inputs, current-loop or 0-10 V signals to drives and actuators, and a managed switch carrying the BACnet/IP layer.
BS EN 61439 Compliance
Every panel we build is verified against BS EN 61439-1/2 — the assembly standard that replaced BS EN 60439. This covers temperature rise, dielectric strength, short-circuit withstand, IP/IK rating, and the documented design verification trail. We supply the full TVSA (Type Verified Switchgear Assembly) certificate at handover.
