Product Description

Model S1028 AC Current Level Detector provides an isolated relay output proportional to the AC input current, with the relay closing at the applicable trip point. The detectors have an input current range from 1Aac to 250Aac, with a frequency range from 360Hz to 900Hz and the detectors withstand, without performance degradation or damage, a continuous overload of 500Aac and a current surge of 1000Aac for 6 cycles.

The S1028 Series delivers performance accuracy over a temperature range from -55°C to +85°C, operates with a supply voltage from +20.5Vdc to +32.2Vdc and with a high precision internal reference guaranteeing repeatable operation. The unit’s brass alloy housing, is hermetically sealed, with the internal components encapsulated creating a rugged and durable transducer, withstanding environments of moisture, humidity, vibration, shock and altitude.

The S1028 AC Current Detector comes standard with a 1.00” (2.54 cm) thru-hole, is light weight and is available with a 9 Pin D-Sub connector. Optional mating connector available.
