+GF+ Signet Controller and Transmitters
The +GF+ SIGNET 8850 Conductivity/Resistvity Transmitter is designed for broad application and ease if setup and use. The unit can be used for conductance, resistance or TDS signal transmission and display.
The Signet 8860 Two-Channel Conductivity/Resistivity Controller accommodates two separate and independent input sources. To control the process, the 8860 is equipped with four dry contact relays and three 4 to 20 mA output loops.
The Signet 8900 Multi-Parameter Controller is field commissioned with the users specified combiation of inputs, outputs and relays using a simple-to-install modular boards into the base unit. Measures Flow, pH, ORP, Conductivity, Pressure, Level and Temperature.
One I/O module is required to build a functional 8900. I/O modules are offered for 4 or 6 sensor inputs with or without two mA or voltage outputs.
Output modules are optional when building an 8900. This module can be used in addition to other outputs that are available in the I/O modules. Active current is powered by the 8900. Passive outputs require an external 12 to 24 VDC power supply.
One power module is required to build a functional 8900. The power module is offered for universal 100/240 VAC or 12 to 24 VDC.
