1157862

Overview

Phoenix Contact part number 1157862 is an Ex i-NAMUR signal conditioner belonging to the MINI MCR-EX series. It functions as an isolation switch amplifier designed for use in hazardous areas. The device operates proximity sensors and switches, transmitting signals to the control level via one solid-state relay output. It requires a 24V DC supply voltage. The unit holds CCC and UKCA Ex (UKEX) certifications, ensuring compliance with specific regional safety standards for explosive atmospheres.

Feature Summary

• Designed as an Ex i-NAMUR signal conditioner for operating proximity sensors and switches
• Transmits signals to the control level via one solid-state relay output
• Certified with CCC and UKCA Ex (UKEX) for hazardous area applications

Applications

• Operating proximity sensors in hazardous areas
• Switch signal conditioning and isolation
• Transmission of sensor signals to control levels

Procurement Notes

Verify that the required certifications match your local regulatory environment, specifically noting the presence of CCC and UKCA Ex (UKEX). Confirm that the 24V DC supply requirement aligns with your system's power infrastructure. Ensure the single solid-state relay output configuration meets your logic interface needs without requiring additional signal splitting or amplification stages.

Selection Notes

Select this component when an intrinsic safety barrier is needed for NAMUR sensors in certified zones. The MINI MCR-EX form factor offers compact DIN rail mounting. Consider the solid-state relay output for switching capabilities. Verify that the specific Ex certification marks are sufficient for your designated hazardous area classification before finalizing the design.

Part Context

This component belongs to the Phoenix Contact MINI MCR-EX series, which specializes in signal conditioners for explosive atmospheres. These devices typically provide galvanic isolation and signal conversion for industrial automation tasks. The series is known for compact designs suitable for dense control cabinet layouts while maintaining strict safety standards for intrinsically safe circuits.

Replacement Considerations

Consult Phoenix Contact cross-reference tools for direct equivalents within the MINI MCR-EX family. Verify that any substitute maintains identical Ex i-NAMUR functionality and output type. Ensure replacement units hold the same CCC and UKCA Ex certifications if these are mandatory for your installation site.
