MOORE 16147-51-02 Smart Signal Isolator/Transmitter

The MOORE 16147-51-02 is a high-precision smart signal isolator and transmitter from Moore Industries' SST series. It accepts a wide range of sensor inputs—including thermocouples, RTDs, millivolt, voltage, and current—and converts them to a standard isolated 4-20 mA or 0-10V output. The device is designed for demanding industrial environments, providing 2.5kVrms isolation, digital calibration, and HART communication for remote configuration and diagnostics.

Universal Input and High Isolation

The 16147-51-02 accepts virtually any industrial sensor type, eliminating the need for separate modules for different signal types. All configuration is performed digitally via front-panel buttons or HART communicator, without the need for jumpers or potentiometers. The 2.5kVrms three-way isolation (input/output/power) breaks ground loops and rejects common-mode noise, ensuring signal integrity in electrically noisy environments such as motor control centers and variable frequency drive installations.

HART Communication and Digital Calibration

The device supports HART communication, allowing remote configuration, calibration, and real-time monitoring of process variables. This feature enables engineers to configure the transmitter from a safe location, reducing field exposure in hazardous areas. Digital calibration ensures long-term stability and eliminates drift associated with analog trim pots. The module is also compatible with asset management systems for predictive maintenance.

Application Domains

The MOORE 16147-51-02 is used in high-temperature furnace temperature measurement (thermocouple input), tank level monitoring (4-20 mA input from pressure transmitters), multi-motor electrical rooms where ground loops are problematic, and chemical reactor temperature control where high accuracy and isolation are critical.
