Universal Signal Isolators, Proline

Knick USA, an ISO 9001: 2008 certified global designer and manufacturer of analog signal conversion technologies for rail, power grid, industrial, marine, automotive and other environments, has introduced its P40000 “ProLine” universal high-voltage Signal Iolators. The Knick USA P40000 ProLine family is specially optimised for DC railway and light rail transit (LRT) applications. Series P40000 models are designed to accept voltages up to 3600 V DC, in accordance with IEC/EN 50124-1 and IEC 62497-1. Electrical shock protection is achieved via protective separation of up to 1800V AC/DC, in accordance with IEC/EN 61140 and EN 61010-1. They are also UL 347 approved above 1500V and feature a mean time before failure of 96 years. Units have also successfully passed high shock and vibration testing in accordance with IEC61373. All of these factors make for a uniquely robust, true “industry best-in-class” signal isolator. Knick USA ProLine signal isolators offer outstanding signal transmission capabilities, including a >0.1% gain error; a cutoff frequency of >5 kHz with optional loss pass filtering; and >0.1 ms rise times. They also offer high immunity to transient noise (T-CMRR >115 dB) with virtually no influence from common mode voltages. Housings are highly durable, thanks to vacuum encapsulation and the incorporation of TransShield technology. This ensures the greatest possible product performance within the most compact modular housing footprint.
