Allen Bradley Safety Relay, 24V AC/DC Supply Voltage, 2 Safety Contacts - CU3 Series - 440R-S35001
Monitor the motion in your single-phase or 3-phase induction motor with this 2-contact safety relay from Rockwell Automation's Allen Bradley range. The unit's safety contacts disconnect when the motor's voltage exceeds 2.5V, and reconnect when the back electromagnetic field dips below this threshold. Thanks to its wide operating temperature range between ‐10°C and +55°C, this unit is durable and suitable for use in challenging conditions.
Small dimensions of 73mm (L) x 45 (W) x 120mm (H), so it fits in tight spaces
Enclosure has an IP40 rating, indicating protection against tools and wires larger than 1mm
35mm DIN-rail mount type, for quick and easy installation
Performance level C, indicating that it's highly reliable
