Phoenix Contact 2865997

The MACX MCR-SL-NAM-R serves as a NAMUR signal conditioner, designed specifically for the operation of proximity sensors and switches. It transmits signals to the control level through a relay output featuring a changeover contact.

Equipped with comprehensive line fault detection (LFD) and 3-way electrical isolation, this device adheres to Safety Integrity Level (SIL) 2 standards. To ensure reliable operation, it includes a screw connection method for easy integration into systems.

Operating within a supply voltage range of 19.2 V DC to 30 V DC, it has a maximum current consumption of 21 mA at 24 V DC. The device supports NAMUR proximity sensors according to IEC/EN 60947-5-6, with a switching threshold of less than 1.2 mA for the '0' signal and greater than 2.1 mA for the '1' signal. The relay contact can handle a maximum switching voltage of 250 V AC with a power rating of up to 500 VA.

The housing, made from flame-retardant PA 6.6-FR, has a degree of protection rated at IP20. It operates effectively in ambient temperatures ranging from -40 °C to 42 °C and is suitable for mounting on a DIN rail according to EN 60715.

This isolation amplifier is further characterized by its compact dimensions, measuring 12.5 mm in width, 112.5 mm in height, and 113.7 mm in depth, making it an optimal choice for space-constrained installations.
