ADVANCED AND CUSTOM OPTIONS

Image: IHP24-AF with a local control panel

Advanced option

The advanced option offers six (6) Digital 24VDC output and four (4) Digital 24VDC wet input. This option is typically used for proportional systems.

The specifications (Dimensions, enclosure etc.) are the same as the IHP24-BF-H. The features and local user interface offered on the Advanced option is identical to the ones on the other IHP24 models.

At the example shown an IHP24-AF (Advanced Flameproof) is fitted with a local control panel containing buttons for open/close and to switch between remote and local control. The local control panel is a custom option which you can read more about below.

 

Custom options

In close cooperation with our sales & engineering team we can provide you a custom solution that meets the exact requirements for your project. Val Controls works directly with end-users, contractors, OEMs and suppliers of SIS and DCS to ensure we deliver the best possible product.

Our custom options for the Hydraulic Positioner are typically various local control panels, custom software solutions or bespoke enclosures.
