DANFOSS
PLUS+1® REMOTE CONTROLS TECHNOLOGY (RCT)
Multilec houses the only RCT build and service centre in Australia.
The RCT centre opened in 2023, one year after becoming a Danfoss authorised distribution partner we found that there was more to offer in the Australian market with the remote control technologies complimenting our PLUS+1 HMI and Controller range.
Ikompact
These Handheld Transmitters exclusively designed for mobile applications, it’s our most commonly used compact Transmitter with 8 and 12 buttons versions.
Optional Stop button complying to Cat. 3-PLe EN12849-1 and SIL 3 IEC 61508 / IEC 62061
This compact unit is our preferred model of choice.
Ikore & Ikargo
These Handheld Transmitters are designed for crane and lifting applications, the Transmitters benefit from having twin-step buttons, inbuilt safety rated STOP button, option of AAA or rechargeable batteries and LCD display on the Ikargo model.
Ikontrol IK2, 3 and 4
These Console Box Transmitters are highly customisable giving the end user the ability to configure and specify the layout and operation of the console box as they see fit.
Multilec can design with the customer in real time on a PC web interface the console box layout; choosing the required buttons, joysticks, switches, LED indicators or LCD colour display.
There is no standard off the shelf design as each unit is manufactured to suit the application.
FAQs
What are Danfoss Radio Remote Controls (RCT)?
Danfoss Radio Remote Controls (RCT) are industrial wireless control systems used to safely operate mobile and stationary machinery. At Multilec Engineering, we supply, configure, and integrate Danfoss RCT systems to suit specific machine and site requirements.
What applications are Danfoss RCT systems typically used for?
Multilec Engineering commonly supplies Danfoss RCT systems for:
- Cranes and lifting equipment
- Construction and mining machinery
- Agricultural machinery
- Industrial material handling systems
- Special-purpose and custom-built machines
What are the main components of an RCT system?
A typical Danfoss RCT solution supplied by Multilec Engineering includes:
- Handheld transmitter (push-button, joystick, or combination types)
- Receiver unit mounted on the machine
- Antennas, wiring looms, and mounting accessories
- Safety circuits including emergency stop (E-stop)
How do Danfoss RCT systems ensure operator safety?
Safety is a core design principle. Danfoss RCT systems incorporate:
- Emergency stop (E-stop) functionality
- Encrypted and secure radio communication
- Automatic safe shutdown on signal loss
- Redundant safety paths (model dependent)
- Compliance with applicable international safety standards
Multilec Engineering ensures correct safety integration as part of system commissioning.
What radio frequencies do Danfoss RCT systems use?
Multilec Engineering supplies new Danfoss RCT systems operating in the 2.4 GHz frequency range, which offers robust performance, global acceptance, and high immunity to interference.
Why 2.4 GHz?
- Globally harmonised licence-free band, simplifying compliance across regions
- Advanced frequency hopping and interference mitigation
- Supports higher data integrity and secure communication
- Well suited to modern industrial environments with multiple wireless devices
Multilec Engineering can also service, support, and repair older Danfoss RCT systems operating in sub-GHz frequency bands (such as 433 MHz, 868 MHz, or 915 MHz), subject to parts availability and regulatory compliance.
What is the typical operating range of an RCT system?
Operating range depends on transmitter type, antenna placement, and environmental conditions. In open areas, ranges may reach several hundred metres. Multilec Engineering can advise on antenna selection and placement to optimise performance.
Can multiple RCT systems operate in the same area?
Yes. Each Danfoss RCT system uses unique addressing and secure pairing, allowing multiple systems to operate in close proximity with minimal risk of cross-interference.
Are Danfoss RCT systems configurable?
Yes. Multilec Engineering configures RCT systems to match machine functionality, including:
- Button and joystick assignments
- Output logic and response behaviour
- Safety interlocks and control modes
How are transmitters paired with receivers?
Transmitters and receivers are securely paired during installation using Danfoss-approved binding procedures. Multilec Engineering performs and verifies pairing as part of system setup.
What power sources are used for RCT transmitters?
Transmitters are powered by rechargeable or replaceable batteries, depending on the model. Multilec Engineering can recommend charging and battery management solutions to suit operational needs.
What happens if the radio signal is lost?
In the event of signal loss, the receiver immediately places the machine into a predefined safe state, such as stopping motion or disabling outputs.
Are Danfoss RCT systems suitable for harsh environments?
Yes. Danfoss RCT equipment is designed for industrial use and offers resistance to dust, moisture, vibration, and temperature extremes. Multilec Engineering selects suitable models based on environmental conditions.
How does Multilec Engineering support troubleshooting?
If a system becomes non-responsive, Multilec Engineering supports fault finding by checking:
- Transmitter battery condition
- Receiver power supply and wiring
- Antenna condition and placement
- Pairing and configuration integrity
- Potential sources of radio interference
Can Danfoss RCT systems be integrated with other control systems?
Yes. Multilec Engineering integrates Danfoss RCT receivers with PLCs, hydraulic valves, ECUs, and other control systems as part of complete machine solutions.
Where can I get support or further information?
