Model classification and hardware configuration

The MVCweb series includes three core models, with main differences in onboard I/O quantity, HMI configuration, and external HMI support capability. The total I/O quantity includes onboard I/O, Panel Bus I/O, and LONWorks Bus I/O.

Model, onboard I/O quantity, total I/O quantity, HMI configuration, external HMI support

MVC-WEB-2014B2B 14 with 52 built-in HMIs (LCD+buttons) not supported

MVC-WEB-2026B2A with 26 built-in HMIs (LCD+buttons) and 600 built-in HMIs is not supported

MVC-WEB-2026B3A 26, 600 without built-in HMI support (including RJ45 interface, can be connected to MVC-2000HMI-A)

Typical I/O types and specifications (taking 26 onboard I/O as an example)

Analog Input (AI): Supports NTC20k temperature sensor, 0-10V signal, maximum transmission distance of 400m.

Digital Input (DI): Supports 24V open circuit/2.0mA closed signal, total counting frequency 15Hz, maximum transmission distance 400m.

Analog output (AO): 0-11V signal (maximum 1mA), maximum transmission distance 400m.

Digital output (DO): Relay normally open contacts (including high surge current type), maximum transmission distance of 400m.

Installation and usage precautions

Wiring requirements

M-Bus/Modbus: Shielded twisted pair cable (J-Y - (St) - Y 2 × 2 × 0.8) is required, with the shielding layer grounded at one end; Modbus only supports daisy chain topology, with branch lengths not exceeding 20m.

Power isolation: It is prohibited to share transformer power supply with other controllers/devices (such as PW M-Bus adapters) to avoid interference.

Electrostatic protection: During installation, it is necessary to follow the rules for electrostatic discharge protection to avoid damaging the equipment.

Accessories and Selection

Essential accessories: detachable terminal plug (TPU-45-01), terminal cover (MVC-80-AC1), cabinet door installation accessories (MVC-80-AC2), strain relief (MVC-40-AC3), etc. (to be purchased separately).

Signal conversion: If you need to convert a 0-20mA signal to 0-10VDC, you can use the auxiliary terminal pack (XS831).

Compliance and Certification

Compliant with multiple international standards: BTL, AMEV AS-A, EN 60730-1/2-9, UL60730, UL916, as well as Ethernet IEEE 802.3, BACnet ANSI/ASHRAE 135-2010.

Document reference: Follow the product manual (EN1B-0567GE51), protocol conformity statement (EN0B-0716GE51), and network security white paper (EN2B-0398GE51).
