*1 The response time, as well as the types and number of inputs and outputs that are available, vary depending on the connected sensor model. For details, see the specific 'MU-N Series User's Manual' for the model that will be connected. *2 1500 mA or less when a sensor is attached, 4 outputs (with loads) are used, and expansion units are connected. *3 20 mA or less: When using the expansion unit. *4 For more information on Control output, External input, and Analog output wire allocation, please refer to the table of 'Power Cable Pin Layout' on page 3 of this manual. *5 Up to 5 N-bus devices, including the main unit (or network unit), can be linked together.
