The Signet 8900 Multi-Parameter Controller takes the concept of modularity to the extreme. Each 8900 Controller is field-commissioned with the users-specified combination of inputs, outputs, and relays using simple-to-install modular boards into the base unit. Configure the system by selecting 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 20 mA 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 Controller will support up to four additional relays via an external relay module.
There are other notable features that the 8900 Controller offers. For example, digital input to the Signet 8900 Multi-Parameter Controller enables longer cable runs and simplified wiring with minimal noise interference. Advanced relay logic allows users to select up to three measurement sources to trigger one relay. Derived measurements include difference, sum, ratio, percent recovery, percent rejection, percent passage and BTU. The menu system can be programmed to display in multi-languages, including English, German, French, Spanish, Italian, and Portuguese.
