Product features
Mode of operation
The UK24MOD allows the actuators to be controlled digitally via the MP-Bus and send back
their current operating status. The control system information and the response is administered
in registers in the UK24MOD and can be processed with Modbus commands. This permits the
actuator functions to be integrated directly into the Modbus.
Sensor linking
One sensor can be connected per MP/MFT(2) actuator. This can be a passive resistance
sensor (PT1000, NI1000 or NTC), an active sensor (output DC 0…10 V), or a switching contact.
This provides a straightforward way of digitising the analogue signal of the sensors with the
Belimo actuator and transferring it via UK24MOD to the Modbus.
MPL actuators don't provide a sensor input.
Installation and commissioning
Installation and wiring
The device is mounted on 35 mm top hat rails. The wiring is accomplished with plug-screw
terminals.
Commissioning and parameterisation
Commissioning requires no configuration tools.
The Modbus parameterisation of the device is accomplished with DIP switches (address, baud
rate, parity, bus terminator, polarisation). The option exists of setting the response delay via
register entry (2..100 ms).
The addressing of the MP actuators is accomplished either with the keys under the front cover
or with the Belimo PC-Tool MFT-P.
The MP-Bus assignment is determined automatically and continuously updated. No backup of
the network structure takes place.
