Stepper Motor Drive Boards

REGULATEURS EUROPA series hydraulic governors may be equipped with a speed setting device which can be adjusted from a
4-20 mA signal. In this instance the speed setting mechanism in the governor is adjusted by means of a stepper motor, which
is controlled by driver M602901F.

The unit complies with the requirements of IEC61000-4-2, -3, -4 and 5 if mounted in a steel plate enclosure. A potential free
change over contact is available for alarm indication. Please refer to the data sheet, which summarises the differences between
builds and provides the specification and connection diagram of the latest build M602901F.

Amplifier Boards

The amplifier module ECM7118 provides an interface between any of the REGULATEURS EUROPA range hydraulic actuators and electronic control units from other manufactures. The module is available in a standard open housing for DIN rail mounting

As a safety feature the module will interrupt the input signal loop if a wire break is detected in the outgoing signal loop to the actuator,
or in case of power supply failure. This enables the control system to detect wire break in the entire loop.

The module is fitted with a self-resetting fuse. The LED will indicate power supply available (green) or fuse interrupted (red). The module will detect an open loop in the output signal. In that instance, or in case of power supply failure, the input signal loop will be interrupted also. This enables the control system to detect failure of the entire loop.

Distributed I/O System

The ICENI range of distributed I/O modules can be used to communicate with PC or PLC equipment or extend the range of the RE Viking35 ECU. The DIN rail mounted modules are designed to be cost effective and easy to configure, via a colour display keypad, without the need for a programmer or laptop. ”ICENI” has been built to a high specification to encompass the extended temperature range of an engine environment but is easily suited to a much wider role; both to enhance RE Control and Monitoring solutions or as a product for other OEMs.

  • Open protocols to PLCs, PCs etc.ICENI node
  • Extended temperature range (-20 to +70 degrees C)
  • Inbuilt user interface for commissioning and support
  • Robust construction
  • Independent electrical isolation
  • Redundant power supply capability
  • "Plug and Play" automatic configuration
  • Cost-effective solution for a wide range of application
