Switch Amplifiers Feature Line Fault Detection

Wed, 08/31/2011 - 8:32am
switch amplifiers PandFPepperl+Fuchs introduced three new Switch Amplifiers with Line Fault Transparency (LFT). NIC2831 and HIC2832 are one- and two-channel switch amplifiers with LFT suitable for mounting on termination boards. The K-System KFD2-SOT2-EX1.N provides line fault transparency to the control system in a standard DIN rail mounting configuration. These one- and two-channel switch amplifiers with LFT significantly reduce the amount of wiring required in hazardous area applications, according to the company. They also provide process automation users with desirable monitoring of field and control lines, and the ability to transfer switch signals on each individual channel. Using switch amplifiers with LFT, switching and fault signals from the hazardous area are simultaneously transferred to the control level via a single output to maximize signal transmission integrity. Even though it is isolated, the amplifier transfers line breakage and short circuit error signals from the input circuit together with the standard signal using a resistive switching output isolator module.
