Switch Amplifiers

Switch Amplifiers with Line Fault Transparency (LFT) reduce the amount of wiring required in hazardous area applications. They also provide process automation users with monitoring of field and control lines and the ability to transfer switch signals on each individual channel. Switching and fault signals from the hazardous area are simultaneously transferred to the control level via a single output to maximize signal transmission integrity. The unit transfers the line breakage and short circuit error signals from the input circuit together with the standard signal using a resistive switching output isolator module.
