Belimo UK24MOD - MP gateway to Modbus RTU

Belimo UK24MOD gateway

UK24MOD provides access to control of actuators connected to MP-Bus and their operating status via Modbus RTU registers. Device assignment on the MP-Bus network is detected automatically and continuously updated.

Key features

• MP-Bus / Modbus RTU (RS-485) interface; up to 8 MP/MPL/MFT(2) or BF-TopLine actuators.
• Nominal supply: AC 24V, 50/60 Hz / DC 24V; supply range: AC / DC 21.6…26.4 V.
• Communication with actuators: Belimo MP-Bus, Client-Server, 1200 Bd.
• Modbus RTU: supported functions 3 and 6; speeds 9'600, 19'200, 38'400, 76'800 Bd.
• Modbus address: 1–247; parity NONE (1, 8, N, 2) or EVEN (1, 8, E, 1), set using DIP switches.
• Response delay: 2…100 ms, set via register; 150 Ω termination and 680 Ω polarisation set using DIP switches.
• Pluggable screw terminals for power supply, MP-Bus and Modbus RTU; RJ12 socket for connecting Belimo Assistant 2.
• Installation in a control cabinet on a 35 mm rail; IP20 protection rating; ambient temperature 0…+40° C.

One sensor can be connected to each MP/MFT(2) actuator: a passive PT1000, NI1000 or NTC resistance sensor, an active sensor with a DC 0…10 V output, or a switching contact. MPL actuators do not have a sensor input.
