Product Description

Model 901B DC Current Level Detector provides an effective and accurate solution to monitor DC current. A conductor wire is routed through a 3/4 inch thru-hole which provides non-intrusive and isolated means to measure desired current. The unit provides two separate outputs: first, “logic high” when the measured current reaches the applicable trip point and second, a 0Vdc to 5Vdc signal directly proportional to the measured input current.

The 901B Series has input current range from 20mA to 5A and an adjustable trip point between 70% and 110% of full scale current. The unit is designed to measure the applicable current while the voltage of the thru conductor reaches levels up to 30kV.  The detector delivers performance accuracy over a temperature range from -20°C to +70°C and operates with a supply voltage from +21Vdc to +27Vdc. The unit’s powder coated steel housing, with the internal components encapsulated, creates a rugged and durable detector.

The 901B DC Current Detectors are available with a header, barrier or connector interface, the connector option is available with mating connector.
