GLT-B Signal Isolation Converter for Automation

Protecting Industrial Control Systems

The GLT-B DC Signal Isolation Converter is engineered for industrial automation environments where reliable signal transmission is critical. It acts as a robust barrier between field-side DC voltage or current output equipment and sensitive receiving systems such as Programmable Logic Controllers (PLCs), Distributed Control Systems (DCS), and precision metering instruments.

By effectively separating these circuits, the GLT-B isolator eliminates ground loop interference, which is a common cause of data inaccuracy and system instability in complex industrial setups. Furthermore, this isolation module converts incoming DC signals into stable, standardized outputs, ensuring seamless communication across devices with incompatible grounding conditions.

Comprehensive Signal Matching Capability

Versatility in signal matching is a core advantage of the GLT-B converter. It is designed to process a wide array of inputs, seamlessly handling standard analog signals such as 4–20mA, 0–10V, 0–5V, and 0–75mV. Beyond standard requirements, it offers exceptional compatibility with non-standard, reverse, and bipolar signals, including 20–4mA, 10–0V, and -10V to 10V.

This comprehensive compatibility is highly valuable for upgrading legacy systems, integrating specialized sensors, or connecting custom controllers that utilize signal ranges incompatible with modern data acquisition modules. Instead of sourcing and installing multiple single-function converters, engineers can rely on the GLT-B to standardize diverse inputs into a unified output format.

Built for Demanding DC Signal Applications

Industrial environments often involve extreme electrical parameters that standard converters cannot handle. The GLT-B signal isolator is specifically built for these demanding applications, featuring exceptional high-voltage and high-current input capabilities. It safely supports input voltages up to ±2000V and input currents up to ±10A, making it an ideal choice for heavy-duty DC measurement and isolation tasks.

These extended input capacities allow the module to directly interface with high-power specialized industrial equipment, motors, and power generation systems where signals far exceed typical process-level ranges. By stepping down and isolating these intense signals before converting them to a standard, safe output for monitoring, the GLT-B acts as a critical safety buffer.
