The Siemens current monitoring relays for IO-Link are suitable for the load monitoring of motors or other loads. In three phases they monitor the rams value of AC currents for overshooting or undershooting of set threshold values. Whereas apparent current monitoring is used above all in connection with the rated torque or in case of overload, the active current monitoring option, which is also selectable, can be used to observe and evaluate the load factor over a motor's entire torque range. It measured value transmission to a controller, including resolution and unit, may be parameterizable as to which value is cyclically transmitted.
