ORDERING INFORMATION

  • Code number: CLSB-[1] Specify a code from below for [1]. (e.g. CLSB-05) Confirm the correct sensor type described on the data sheet of the combined transducer/transmitter module. [1] INPUT R5: 5 A 05: 50 A 10: 100 A 20: 200 A 40: 400 A 60: 600 A CAUTION Before you remove the sensor module or mount it, turn off the input signal for safety. While the line is alive, the module’s cores, attracted to each other, may be hard to separate.
