Interface Modules

Below are a list of the interface modules available. All these modules are designed to be used with the Fieldbus P-NET (refer to Fieldbus). The modules provide the ability to interface with almost any process sensor or control, providing the means of distributing control/intelligence. The modules can be supplied as separate units for customers to build their own system or will be used by us to provide a complete system to suit our customers requirements.

Also detailed below are the communication modules, which provide the ability to connect a P.C. using VIGO to the P-NET or a RS232 devices to P-NET.

To obtain further information on any of the modules below, please use the Information request Form below.
