GF Signet 8900 Relay Modules

The GF Signet 8900 multi-parameter controller takes the concept of modularity to the extreme. Each GF Signet 8900 multi-parameter controller is field commissioned with the user's specified combination of inputs, outputs, and relays using simple-to-install modular boards into the base unit.

The GF Signet 8900 multi-parameter controller includes a back-lit LCD display. Available with a selection of plug-in modules for either four or six input channels which accept any of the GF Signet sensors listed below, and/or other manufacturer's sensors via a 4 to 20mA signal converter (GF Signet i-Go 8058 Signal Converter).

To complete your GF Signet 8900 multi-parameter controller, 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 GF Signet 8900 multi-parameter controller will support up to four additional relays via an external relay module.

There are other notable features that the GF Signet 8900 multi-parameter controller offers. For instance, digital input to the GF Signet 8900 multi-parameter controller enables longer cable runs and simplified wiring with minimal noise interference. Advanced relay logic provides operators an "and / or" logic to produce high / low alarms. Derived measurements include difference, sum, ratio, percent recovery, percent rejection, and percent passage - and now with BTU.
