Designed for maximum user versatility, GF Signet is offering their 3-8900 Multi-Parameter Controller. The field commissioned 3-8900 is equipped with users-specified combination of inputs, outputs, and relays using modular boards into the base unit that are effortless to install. Users can configure the controller by choosing either two, four or six input channels as well as power module with universal AC line voltage or 12 to 24 VDC.
The 3-8900 allows for longer cables to be run and easy wiring with little noise interference. The advanced relay logic enables users to choose up to three measurement sources to trigger one relay. Derived measurements include difference, sum, ratio, percent recovery, percent rejection, percent passage and BTU.
