Premium Signal Conditioning: Phoenix Contact MACX MCR-EX-SL-RPSSI-I Repeater Power Supply
In hazardous industrial locations like chemical plants, oil refineries, and offshore platforms, keeping signal measurements accurate while ensuring flawless explosion protection is a major challenge. For global procurement managers, EPC contractors, and automation engineers looking for zero-compromise process safety, the Phoenix Contact MACX MCR-EX-SL-RPSSI-I intrinsic safety isolated barrier is the premium global industry standard.
As part of Phoenix Contact’s highly trusted MACX Analog family, this single-channel repeater power supply safely transfers analog 4–20 mA signals from hazardous areas (Zone 0/Class I, Div. 1) to the safe control room with exceptional precision and full HART protocol transparency.

Why Global Buyers Choose MACX MCR-EX-SL-RPSSI-I
1. Ultra-Slim 12.5mm Space-Saving Design
Control cabinets in large-scale plants are often pushed to their physical space limits. The MACX MCR-EX-SL-RPSSI-I packs high-performance isolation into an ultra-slim 12.5 mm wide housing. This allows you to fit significantly more channels per DIN rail meter compared to traditional 20mm barriers, lowering enclosure hardware costs and reducing the footprint of your marshalling cabinets.
2. Bidirectional HART Protocol Transparency
Modern process facilities rely on smart field instruments for configuration and predictive diagnostics. This repeater power supply features full HART protocol transparency. It transmits digital data superimposed on top of the 4–20 mA analog loop bidirectionally without distortion. Your engineers can calibrate, configure, and monitor smart field transmitters right from the control room.
3. Premium 3-Way Galvanic Isolation & Safety
Electrical noise and ground loops can severely warp your data or permanently damage your expensive PLC/DCS analog input cards. The MACX MCR-EX-SL-RPSSI-I provides absolute three-way galvanic isolation between the input, output, and power supply. Certified up to SIL 2 (Safety Integrity Level) or SIL 3 in redundant architectures, it guarantees dependable process protection for your critical safety loops.
