Signet 8900 Multi-Parameter Controller

Features

Member of the ProcessPro® Family of Instruments

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. 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 ±10%, regulated.

• Measures Flow, pH, ORP, Conductivity, Pressure, Level and Temperature

• Multi-language display

• ¼ DIN enclosure

• Up to 4 analog outputs

• Up to 8 relays

• 12 to 24 VDC or 100 to 240 VAC ±10%,

regulated power

• Digital communication allows for extended cable lengths and easy wiring

• Accepts 3rd party 4 to 20 mA output devices when used with 8058 signal converter

• Available with 2 to 6 channels

• Simultaneous BTU Calculations with

Heating & Cooling Totalizers per calculation

MEASURING EQUIPMEN

77CJ

If more features are needed, analog output and relay modules are available and easily installed. Plus, the 8900 will support four additional relays via an external relay module. There are other notable features that the 8900 offers. For instance, digital input to the 8900 enables longer cable runs and simplified wiring with minimal noise interference. Advanced relay logic allows users to select up to 3 measurement sources to trigger 1 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.
