Key Features and Applications
Signal Conversion & Isolation: Converts a 4-20mA current signal into a voltage signal while providing critical 3-way isolation to prevent ground loops and protect equipment from noise and surges.

Integrated Alarm Monitoring: The two relay outputs can be set to trigger based on high/low process conditions (e.g., high pressure, low flow), providing direct alarm or control functions without a separate controller.

Transmitter Power: The built-in 24V DC supply powers the field transmitter, simplifying wiring and reducing the number of components in the cabinet.

Versatile Output: The voltage output is compatible with a wide range of equipment like PLC analog input cards, recorders, and displays.

Applications: Used in virtually every industry for:

Isolating and converting signals from pressure, temperature, flow, and level transmitters.

Providing alarm trips for safety or process interlock systems.

Interface between field devices and control systems (DCS/PLC).
