In chemical processing facilities, radar and pressure transmitters are often installed in areas where explosive gases may be present. The repeater power supply ensures these devices are powered safely while transmitting accurate 4…20 mA signals to the control room. Its ability to provide isolation between the hazardous zone and safe area prevents risks of cross-faults. With rapid step response and support for HART communication, operators can trust the measurements for level control, helping prevent overfill incidents and improving process safety.
On offshore oil platforms and refineries, actuators and valve position sensors must operate reliably under hazardous conditions. This repeater power supply enables safe transmission of signals across Ex zones, ensuring that safety valves respond quickly to control system commands. The HART transparency allows real-time diagnostics and adjustments, reducing downtime during maintenance. Its SIL 3 certification ensures that critical safety systems meet the required integrity standards, providing confidence in the protection of people, equipment, and the environment.
Pharmaceutical plants require extremely accurate measurement data for batch production and quality control, often within classified hazardous areas. The repeater power supply allows field devices in these zones to transmit process data without compromising safety. Its five-way isolation maintains signal integrity over long distances, ensuring precise monitoring of temperature, pressure, or flow. With its compact design and robust certifications, it supports seamless integration into validated systems, reducing risks of process interruptions and ensuring regulatory compliance in sensitive production environments.
Power plants rely on continuous monitoring of key variables such as vibration, pressure, and temperature. The dual-channel design of this repeater power supply allows redundant sensor outputs to be routed to both safety controllers and data acquisition systems. This guarantees that if one channel fails, monitoring remains uninterrupted. Its fast signal transfer and high accuracy provide operators with dependable real-time data, while safety approvals support its use in critical energy applications. This redundancy minimizes downtime, enhances reliability, and improves predictive maintenance strategies.
