The CS‑652 Series current sensors monitor line current for electrical loads such as pumps, conveyors, machine tools, or fans and output a 4‑20 mA Vdc signal to represent the load current. The CS‑652 is loop‑powered and requires a 15‑30 Vdc supply. The sensors are typically used to monitor motor operation and can be used to determine motor failure, belt loss, machine feed rates or tool wear.
