CR9380 Low cost, self powered, fixed set-point, Split Core AC Current Switch

The CR9380 Series is a low cost, self-powered, fixed set-point Split Core Current Switch designed for applications that require an on-off indication of current flow. Current levels above the guaranteed full-on level will turn the output to full on. The Current Switch is recommended only for applications where the continuous operating current is above the rated full on level of 350 mA. Operation below this point will not drive the output device full-on and derate the output ratings. The unit is available with a NPN or PNP output transistor for switching DC and a ACA output for AC switching. Connections can be made directly to items such as a PLC or electromechanical relay. Note that connections made directly to an inductive device such as an electromechanical relay will require a customer supplied clamping diode for DC operation or a snubber network for AC operation.
