Hazardous area repeater D5212Q

RS-485interfacecurrent

The D5212 Repeater Power Supply is a high-integrity SIL 2 analog input interface module designed for safety-related systems in high-risk industries such as oil & gas, chemical, petrochemical and process automation. It provides a fully floating 24 Vdc supply for powering conventional 0/4-20 mA two-wire transmitters in Hazardous Areas (Zone 0/Div. 1) and accurately repeats the current signal to drive Safe Area loads with three-port isolation between input, output and supply. The D5212 supports active or passive 4-20 mA inputs, source output up to 300 Ω, and advanced signal processing including multiplexing, scaling, duplication, inversion and mathematical operations such as sum, difference, minimum and maximum. A programmable alarm output with user-settable trip points, hysteresis and delays enhances safety and control. Configuration, monitoring and diagnostics are available via Modbus RTU RS-485, enabling seamless integration into industrial control systems. The module features high precision microprocessor A/D conversion, input and output short-circuit protection, high channel density with four channels per unit, and compact DIN-rail mounting for efficient installation. Certified for functional safety to SIL 2 and suitable for hazardous and safe area signal conditioning, the D5212 is ideal for demanding industrial control and safety applications.
