The Phoenix Contact MACX MCR-EX-SL-RPSSI-I is an intrinsically safe repeater power supply and input signal conditioner designed for hazardous area applications. This device transmits supplied or active 0/4-20 mA signals from the Ex (explosive) area to a load in the safe area, supporting both active and passive loads. It features HART transparency for digital communication overlay, three-way galvanic isolation for enhanced safety, and SIL 2 compliance according to IEC 61508 for functional safety applications. The compact 12.5 mm wide housing is suitable for DIN rail mounting, making it ideal for space-constrained control panels. The module utilizes screw connection terminals with integrated sockets for HART communicators, providing reliable signal transmission and isolation between intrinsically safe circuits and control systems in process automation and industrial monitoring applications.
