Multi-Parameter and Multi-Channel Instrument – ProcessPro Family
8900 Multi-Parameter Controller
The Signet 8900 Multi-Parameter Controller takes the concept of modularity to the extreme. Each 8900 is field commissioned with the users specified combination of inputs, outputs, and relays using simple-to-install modular boards into the base unit. To assemble a controller, there is a choice of two base units offered with a choice of back-lit LCD or vacuum fluorescent display. Then, continue building with a selection of plug-in modules for either two, four, or six input channels which accepts any of the Signet sensors listed below, and/or other manufacturer’s sensors via a 4 to 20mA signal converter (Signet Model 8058). To complete your unit, choose a power module with universal AC line voltage or 12 to 24 VDC.
If more features are needed, analog output and relay modules are available and easily installed. Plus, the 8900 will support up to four additional relays via an external relay module.
There are other notable features that the 8900 offers. For instance, digital input to th 8900 enables longer cable runs and simplified wiring with minimal noise interference. Advanced relays provide "and/or" logic to produce hi/low alarms. Derived measurements include difference, sum, ratio, percent recovery, percent rejection, percent passage, and now with BTU. The menu system can be programmed to display in multi-languages including English, German, French, Spanish, Italian, and Portuguese.
