+GF+ Signet Controller and Transmitters

Direct Conductivity/Resistivity Module. The Direct Conductivity/Resistivity Module interfaces Signet 2819-2823 and 2839-2842 Conductivity electrodes directly to the 9900.

The 4 to 20 mA Output Module adds a second 4 to 20 mA Output to the 9900 Transmitter (Generation III and later). Each of the outputs can be used to output the primary and/or secondary measurement.

Relay Module. This module adds two programmable dry-contact relays to the standard Open Collector output in the base unit.
