Solartron Metrology – Absolute TTL Module (ATM)
TTL/RS422 Differential Quadrature is one of the most commonly used methods of communication between Linear Displacement Transducers and Control or Data Acquisition systems. Its simplicity of interfacing with programmable systems also makes it one of the most cost effective.
The Solartron ATM module is coupled to Solartron Absolute Position Transducers and converts the output to a digital signal. The transducer signal conditioning is designed such that unlike incremental TTL systems, it will not suffer from “over speeding” or lose position during a power down.
