The DEIF TAC-311DG is engineered to provide precise measurements of AC voltage in power generation and distribution systems. It takes raw AC voltage from a busbar or generator and converts it into a proportional DC analog signal (such as 4-20mA or 0-10V). This high level of accuracy is vital for control systems that rely on voltage data to manage load sharing or reactive power compensation.
A critical feature of the TAC-311DG is its robust galvanic isolation between the input, output, and power supply circuits. This protects the sensitive low-voltage electronics of the PLC or control system from high-voltage transients and ground loops. In industrial environments where electrical noise is prevalent, the TAC-311DG ensures that the signal remains clean and accurate.

The TAC-311DG is designed for long-term stability. Its internal circuitry is temperature-compensated to prevent signal drift across a wide range of ambient operating temperatures. Excellent linearity ensures that the output signal accurately reflects the input voltage across the entire measurement range, providing reliable data for both monitoring and protection logic.
Space in control cabinets is often limited. The TAC-311DG features a compact, slim-line housing designed for standard DIN rail mounting. The terminal arrangement is optimized for easy wiring, reducing installation time. Its rugged plastic enclosure is flame-retardant and designed to withstand the typical mechanical stresses of an industrial switchboard.
Whether used for monitoring mains voltage in a commercial building or generator output on a ship, the TAC-311DG is a versatile tool. It is often paired with DEIF indicators or controllers to provide a complete measurement solution. Its reliability and accuracy have made it a standard component for electrical engineers focusing on power quality and system efficiency.
