Description
Plug in Modules
Optional modules are available to customize your 9900: All modules come enclosed in a plastic cover. Modules are field installable and replaceable any time.
Relay Module (Panel Installations only)
This module adds two programmable dry-contact relays to the standard Open Collector output in the base unit. Dry-contact relays are electromechanical switches with a moving contact armature. They are suitable for many general purpose applications, AC or DC, including loads up to 250 V. Install RC Filter kits (3-8050.396) on relays used to switch motor or inductive loads.
Direct Conductivity/Resistivity Module
The Direct Conductivity/Resistivity Module interfaces Signet 2819-2823 and 2839-2842 Conductivity electrodes directly to the 9900. The module also provides filtering and conditioning. The 2850 Sensor Electronics can be used in place of the Direct Conductivity/Resistivity Module wired through the 9900 Digital (S3L) input.
H COMM Module (HART)
The H COMM Module enables communication between the 9900 and a HART-enabled device. The HART (Highway Addressable Remote Transducer) Protocol superimposes digital signals on top of the 4 to 20 mA analog signal.
Batch Module
The Batch Module adds batch capability to the 9900 Transmitter (Generation II and newer). It is compatible with all Signet flow sensors. Up to 10 batch sizes can be stored in one 9900 with customized names and K-Factors available for each batch.
4 to 20 mA Output Module
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. Outputs have individual settings available.
