Current monitoring relay for IO-Link, can be attached to 3RT2 contactors, size S0 Apparent/active current monitoring 4-40 A, 20-400 Hz, 3-phase Supply voltage 24 V DC 1 changeover contact Monitoring for current overshoot and undershoot Current asymmetry Phase failure, wire break Phase sequence, residual current Blocking current, switching cycle and operating hour counter Warning and alarm thresholds AUTO or MANUAL RESET Start-up delay 0-9999.9 s Switch-off delay 0-9999.9 s Restart delay 0-300 min Screw connection technology SIRIUS 3RR2 monitoring relay for connecting to SIRIUS 3RT2 contactors or for stand-alone installation for multi-phase current monitoring of the entire system or the driven process. Reliable monitoring for cable breakage, phase failure, phase sequence, residual current, motor blockage and much more increases system availability. Actual value displays, status messages and clear error messages enable fast and reliable diagnosis. Control connection via IO-Link is also possible. You also save costs because only one device is required to monitor a motor along the entire torque curve and no separate current transformers are required. Direct installation on the 3RT2 contactors means there is no additional wiring work in the main circuit. You also benefit from the wide-voltage power supplies for worldwide use. Analogue adjustable, 2-phase variants and digitally adjustable, 3-phase variants (with and without IO-Link) are available, each in three sizes with different current measuring ranges, with two different supply voltages and two connection types. Suitable supports are available for individual installation of the 3RR2 monitoring relays. SIRIUS relays - a program for all situations.
