SCMIII FIELD : Belt feeder control module

SCMIII FIELD : Advanced digital regulator and controller for belt feeder

The SCMIII FIELD, or third-generation Smart Control Module, is an intelligent control module that consolidates control and regulation functions for industrial belt feeders used in continuous dosing or batch processes.

This latest-generation controller manages the entire operation of a weigh belt feeder, centralising data from sensors such as weighing, speed and index. With its unique advanced computing power, it simplifies flow, totalisation, and regulation measurements for the whole range of industrial dosing processes. Its integrated colour display shows visual graphs in real time, allowing you to monitor the flow rate in relation to the set point. You can graphically observe the evolution of your process for continuous improvement and proactive maintenance.

The SCMIII FIELD is compatible with all HASLER Group belt feeders and is also available in a switch cabinet version : SCMIII PANEL.

Advantages of the SCMIII FIELD regulator and controller

Colour touch screen (PDU) for efficient remote management

The SCMIII touch screen offers remote configuration and monitoring, contributing to simplified, proactive maintenance.

Secure backup

Using the memory extension provided by the SD card, the device is ideal for continuous or batch applications. Fast backup and instant restoration of software and all individually defined parameters are guaranteed.

Advanced connectivity

Up to 24 programmable digital inputs and 5 programmable analogue inputs.

Flexible communication

The numerous communication options on the SCMIII mean it can be easily integrated with a wide variety of control systems, whether PLCs, PCs, standard fieldbuses, Wi-Fi or Ethernet networks, or other I/Os.

Display system

The SCMIII FIELD is equipped with an integrated visual graph plotter, allowing you to monitor the flow rate according to the set point and to visually observe all the functions in real time. Up to four graphs can be displayed in real time.

Secure advanced remote management

The SCMIII uses the latest technologies available, enabling it to manage and control multiple devices. The SCMIII FIELD can also be linked to a mobile application for even more remote and secure management.

Immediate display of inputs/outputs and other module functions

The SCMIII offers an intuitive interface that makes it easy to monitor and control I/Os and functions.

Fully removable stainless-steel chassis

The new chassis is even more robust, making it easier to maintain and adjust.

Easily detachable circuit boards (CPI and I/O control)

The SCMIII boards are designed to be easily removed and replaced, simplifying maintenance and upgrade operations.

Simplified replacement

Simplified replacement of an SCMII/HF9 with an SCMIII.

Description of the SCMIII FIELD regulator and controller


The SCMIII FIELD digital controller and regulator is the ideal solution for batch or continuous belt feed applications.

The SCMIII FIELD now incorporates the latest innovations in human-machine interface design. It has a satellite module, the Process Display Unit (PDU) which features a colour touch screen, enabling the controller to be managed remotely. For the ultimate user experience, the equipment can also be managed via an optional mobile application (please contact us).

The SCMIII FIELD is compatible with all HASLER Group belt feeders and is also available in a switch cabinet version: SCMIII PANEL.

This digital equipment regulates and controls all HASLER Group belt feeders by calculating flow rate, totalisation, and control signals using its advanced calculation system.

Two types of weight sensors can be used and are compatible with the SCMIII FIELD:

/ Analogue sensors: based on a strain gauge sensor (4 or 6 wires via digital converter with over 65,000 points)
/ Digital sensors: SFT type (one million points)

All the information gathered by the system is presented visually on the touch screen and can be transmitted via communication protocols: Open Modbus/TCP (Ethernet RJ45), Modbus RTU (RS422), Profibus DP (RS485) and Profinet (Ethernet RJ45)

It offers the following functions:

/ Remote controller management (PDU)
/ Multilingual mode
/ Input/output display
/ Graphical display of flow rate
/ Time stamping and alarm history
/ Integrated diagnostic tools
/ Weight converter (for adding up to three weight measurement points)
/ Mobile application (optional)

Compatibility :
The SCMIII can be combined with all HASLER Group belt feeders, including:

/ Flow meters : FLOW (impact plate), GRAN
/ Loss-in-weight feeders : RBP
