In oil refineries and gas processing plants, temperature transmitters are often located in areas with explosive risk. These transmitters must deliver precise data to the control room without increasing ignition hazards. The MACX MCR-EX-SL-RPSSI-2I provides an intrinsically safe 4–20 mA loop supply while isolating the signal and duplicating it across two outputs. One channel can be used for process monitoring, while the second is reserved for maintenance or redundancy. With HART transparency and SIL 2 certification, operators can remotely configure devices and ensure reliable operation, even under harsh conditions where continuous accuracy and safety are essential.
Large production facilities often spread sensors across wide areas, where signals must travel long distances to central control systems. Without proper isolation, these signals may degrade or face safety limitations. By using the MACX MCR-EX-SL-RPSSI-2I, engineers can extend reliable communication between field instruments in hazardous areas and controllers in the safe zone. Its compact DIN-rail housing and low power consumption make it practical for installation in junction boxes or control cabinets. Dual outputs allow the same signal to be routed to multiple systems, reducing wiring complexity while maintaining compliance with intrinsic safety requirements.
Chemical processing often demands redundant signal paths to protect critical operations such as reactor control or dosing systems. The MACX MCR-EX-SL-RPSSI-2I enables dual isolated outputs from a single input signal, allowing the same measurement to feed both a control system and an independent safety circuit. This setup ensures that if one channel fails or becomes corrupted, the second channel continues to provide accurate data. Integrated error diagnostics based on NAMUR standards further enhance fault detection. By combining redundancy, precision, and intrinsic safety, the device strengthens overall system reliability in high-risk industrial environments.
Manufacturing sites with heavy machinery and electromagnetic interference often struggle with clean signal transmission. Sensors measuring variables such as pressure, level, or vibration can produce noisy data that undermines control accuracy. The MACX MCR-EX-SL-RPSSI-2I solves this with three-way isolation, shielding both the input and outputs from disturbances. Its slim 12.5 mm housing saves valuable panel space, while high accuracy ensures operators receive trustworthy information. With built-in HART transparency, plant engineers can perform diagnostics and adjustments remotely, reducing downtime. This makes it a robust choice for maintaining efficiency and safety in demanding production environments.
