Phoenix Contact 2906164

The limit value switch provides an Ex i input designed for active current and voltage signals, integrated with a relay output configured as a changeover contact. It allows for precise adjustments through DIP switches and a potentiometer, ensuring a tailored response to specific operational needs. With galvanic 3-way electrical isolation, this device meets rigorous safety standards, achieving up to SIL2 (SC3) and PLc Cat.1 ratings.

Designed for robust performance, the product operates efficiently with a nominal supply voltage range of 12 V DC to 24 V DC, accommodating variations from -20% to +25%. It consumes a typical current of 38 mA at 24 V DC, with a maximum consumption of 90 mA at 10 V DC. The switch exhibits a switching point accuracy of less than 0.1% and a step response of 22 ms, ensuring reliable and quick signal management.

Connections are facilitated via screw terminals with a stripping length of 7 mm, supporting rigid and flexible conductor cross-sections from 0.2 mm² to 2.5 mm². The device is constructed from PA 6.6-FR material, rated V0 for flammability, and is suitable for mounting on DIN rails. Additionally, it complies with the EMC directive, ensuring electromagnetic compatibility and operational integrity.
