+GF+ Signet

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.

Relay modules are optional when building an 8900. Relay modes of operation include off, low, high, window, USP, totalizer volume, advanced, proportional pulse, pulse width modulation, volumetric pulse.

The 8059 External Relay Modules supplement the output capabilities of certain host instruments such as the 8900 Multi-Parameter Controller. AC-powered versions accept universal line voltage, and also provide 24 VDC output that can be used to power the host instrument or other device(s).

- Relay Outputs: 2 or 4 external contact relays. SPDT 250VAC/30VDC/5A

- Compatible Instruments: 8900 (S3L Instruments only)

The Signet 9900 Transmitter provides a single channel interface for many different parameters including Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level, Dissolved Oxygen, and other sensors that output a 4 to 20 mA signal. The 9900 offers complete flexibility, plug-in modules allow the unit to easily adapt to meet changing customer needs.
