The LED Studio's replacement for the IMP Data Acquisition system

The Solartron distributed data acquisition network consisted of a number of distributed front-end measurement devices called Isolated Measurement Pods (IMPs) and a proprietary local area network called S-Net. All IMPs possess an on-board microcomputer for data conversion, validation, timing and local data buffering. The S-Net is a twisted pair cable that can connect up to fifty multi-channel IMPs and is capable of processing up 1,000 channels per second.
The distributed network itself could extend over a distance of one mile. As well as handling communications and data, the S-Net also supplied power to the IMPs.

The current offering is limited to the equivalent of the 35951C IMP - 20 Channel Analogue Reed Relay. This imp replacement will even take existing connectors so as to minimise wiring costs.

The other modules in the range will follow shortly:

• 35951A IMP - 20 Channel Analog FET
• 35951B IMP - 10 Channel Strain Gauge
• 35951D IMP - 4 Channel Analog Output
• 35951E IMP - 20 Channel 500 Volt Isolation
• 35951H IMP - 20 Channel Universal
• 35951J IMP - 20 Channel Universal with 500 Volt Isolation
• 35952A IMP - 20 Channel Digital Input/Outputs
• 35952B IMP - 32 Channel Digital Input/Output IMP

Solartron also offered identical measurement capability in a card-mounted form, known as IMCs (Isolated Measurement Cards), as an alternative to the distributed discrete IMPs. Theses will be also be developed later.

The replacement 4B and 4C interface will work in exactly the same way providing a seamless hardware and firmware interface into existing software system packages such as:

• Citect Intellution Fix/Fix Dynamics


• Factorylink Wonderware InTouch


• GE Cimplicity Zeefax PowerPAC™
