D6000 Galvanic Isolators
G.M. International D6000 is a DIN-rail family of galvanic isolators that safely isolates 4–20 mA and voltage process signals. With 1/2/4/8-channel options, 3/6/12 mm channel pitch, and plug-in terminals, it shortens installation and service on PLC/SCADA lines. By cutting ground loops and noise, it boosts measurement accuracy; SIL2/SIL3 (TÜV) ensures consistent signal isolation for petrochemical, energy, and pharmaceutical plants.
Power/Status/Fault LEDs under the transparent front cover and a laser-marked housing simplify error-free field wiring. Engraved, removable terminals shorten maintenance; configuration can be done from the side panel or the connector front. With a compact 120×123×12.5 mm body (D60xx) or 22.5 mm width (D62xx), it occupies minimal panel space.
SIL3 2-Wire HART® Transmitter Power Supply
D6011 Repeater Power Supply powers 2-wire 4–20 mA transmitters and repeats the loop current to the load, meeting SIL3 safety. A fully floating DC supply and bidirectional HART® enable secure power and data between the field device and control system. Three-port isolation (input/output/power), short-circuit protection, and high accuracy cut false readings and failure risk in hazardous processes. The dual-channel architecture saves panel space and lowers total cost in multi-point measurements.
SIL2 2/4-Wire HART® Transmitter Power Supply
D6015SK Repeater Power Supply is engineered for applications requiring SIL2, compatible with 2/4-wire 4–20 mA transmitters. Active/passive inputs and source/sink outputs let a single module match different transmitter types. It passes HART® bidirectionally while protecting the system with three-port isolation (input/output/power) and short-circuit robustness. High accuracy minimizes drift in critical pressure/temperature measurements, and the compact housing saves panel space and reduces installation cost.

Maximum Security On Process Lines
Galvanic isolators are used at critical points of process lines, handling signal transfer between the field transmitter and the control system. 4–20 mA analog signals from pressure, temperature, level, or flow instruments are safely passed through the isolator to PLC/DCS systems, eliminating ground loops and line noise. Models with HART® allow uninterrupted device configuration. Engineers typically place isolators in the field cabinet, marshalling panel, or at the control room entry to ensure safety-certified isolation and long-term system stability.
