HYDRAULIC POSITIONER FOR INDUSTRY

IHP24

The IHP24 range offers the best in performance and user-friendliness, combining these in a very compact enclosure.

To be used for valve positioning and has an integrated microprocessor with very flexible software, so the positioner fits almost any hydraulic rotary, linear, double acting, spring return and stepping actuator on the market. The IHP range offer several advantages:

 

IHP24-B

The IHP24 Basic is an affordable hydraulic positioner which offers:

  • Smart positioner for hydraulic actuators
  • Spring return and double acting actuator control
  • Intelligent valve positioning
  • Automatic intelligent calibration
  • User-friendly menu
  • Flexible and configurable
  • Ultra low power design
  • Configurable by ValConnect software
  • Basic pump controller
  • 4-20mA control signal
  • 4-20mA transmitter signal
  • Potentiometer or 4-20mA loop as position feedback
  • 4x24VDC separate outputs for controlling solenoid valves
  • HART, Wireless HART, Modbus, Foundation Fieldbus and Profibus communication

IHP24-A

In addition to the functionality as the IHP24 Basic the IHP24 Advanced offers the following options

  • Control for proportional valves
  • Advanced pump controller
  • 4-20mA control signal
  • Potentiometer or 4-20mA loop as position feedback

 

The IHP24-A is the most flexible positioner in the range. The standard configuration is designed to be able to handle all tasks a positioner could be used for. Furthermore it is equipped with an extension interface which makes it possible to add extra hardware functionality on customer request.

The IHP24-A offers a large range of connection possibilities. It offers inputs for several 4-20mA sensors and digital signals which make it possible to configure the positioner to control or monitor other applications connected with the valve like a pump unit.

How it works

The IHP24 uses Solenoid Operated on/off Valves, SOV, to move the actuator to the requested set point. It has 4 or more outputs to control SOV’s depending on the model. The IHP24 is designed so it can use any solenoid valve on the market. The unit will automatically adapt the regulator to the performance of the complete system, during an automatic calibration. The desired position of the valve is sent to the IHP24 via the 4-20mA control loop or a communication protocol. The actual position is measured by the IHP via a potentiometer or a 4-20mA sensor. The set point and position signal is compared and the actuator is moved to the requested position.

CONTROL

The IHP24 comes as standard with the following control and communication:

- 4-20mA Control loop with HART
- 4-20mA Position feedback

Its is possible to add the following communication buses:

- Foundation Fieldbus
- Modbus

POSITION FEEDBACK

The IHP24 uses a signal from the actuator/cylinder to know where it is.

The IHP24 accepts the following signal types:

- 4-20mA - 2-wire
- 4-20mA - 4-wire
- 3-wire potentiometer

POWER

The IHP24 is powered through a 24VDC power supply.

This power supply also feeds the solenoid valves and the sensors.

HYDRAULIC SYSTEM

All our typical designs controls 2 solenoid operated valves, but some of the IHPs can control up to 4 solenoid valves. The positioner is also easily adapted to any already existing control systems or other designs.

Some of the hydraulic examples is shown here.
