Gateways MP / Modbus RTU

UK24MOD

With the UK24MOD gateway, up to 8 MP-Bus-capable Belimo actuators can be integrated on an RTU (RS-485) modbus. The UK24MOD allows the actuators to be digitally controlled via the MP-Bus and send back their current operating status. The information on the controls and feedback is managed in UK24MOD and processed with modbus commands

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...10V), 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.

Very simple commissioning

The modbus is parameterised with DIP switches (address, baud rate, bus termination, polarisation). The response delay can be optionally adjusted via a register entry.

The MP-Bus assignment is automatically established and continuously updated.

Suitable actuators can be selected from the bus device selection tool.

BKN230-24-MOD

Belimo field unit BKN230-24-MOD. Fire protection with Modbus RTU.

The integration of motorised fire dampers into Modbus RTU has now become simpler and less expensive. The new communication and power supply unit BKN230-24-MOD allows direct connection of the Belimo fire damper actuator via Modbus RTU to the central controller. The damper position, the status of the optional smoke detector and the thermoelectric tripping device can be visualised just as readily as any fault messages which may arise. This creates transparency, simplifies monitoring and thus enhances safety for people and property in buildings.

Modbus actuators with sensor interface

Actuator with integrated interface for Modbus RTU (RS-485) for the motorisation of dampers, characterised control and other valves. The connection is made by cable.

Sensor interface

One active or passive sensor or one switching contact can be integrated per actuator in the network. This makes conventional sensors capable of communication in the simplest way imaginable.

Parameterisation

In addition to such communications parameters as address, baud rate and transmission format, other actuator parameters such as running time and scaling can also be set with the Service Tool ZTH EU.

Variants with RJ12 connection socket

Actuators with RJ12 connection socket, without sensor connection, are available for the complete Modbus assortment on demand.
