The APC-SV4 and APC-SV8 Step Controls have been designed from the ground up for easier setup, better performance, higher reliability and RoHS compliance. The footprint and output connections are the only thing that is common between the APC-SVX and the R850. While the R850, is an older design, the APC-SVX utilizes the latest Microcontroller technology to reduce the component count and provide increased reliability and performance. Specific performance advantages such as the Hi resolution Vernier output will increase the temperature stability of the process. Due to the FLASH Microcontroller technology, the program can be customized to meet the requirements of applications that are beyond the standard feature set.
