Product Description

Model S201 DC Current Level Detector features an effective and accurate solution to monitor DC current. A conductor wire is routed through a 3/8 inch thru-hole which provides non-intrusive and isolated means to measure desired current. After input current reaches the desired threshold, the relay closes. A high precision internal reference guarantees repeatable operation. The detector has trip point set to 1.0Aac with 100Adc of nondestructive current carrying capability.

The S201 Series delivers accuracy over a temperature range from -55°C to +70°C and operates with a supply voltage from +24Vdc to +32Vdc. The unit’s powder coated steel housing, with the internal components encapsulated creates a rugged and durable detector.

The S201 DC Current Detectors are available with a header, barrier or connector interface, with the connector option available with mating connector.
