RMC200 S8

8 SSI or MDT Inputs

S8 Module

The S8 module provides eight inputs, individually software selectable as SSI, or as magnetostrictive Start/Stop or PWM inputs. One RS-422 quadrature input (A+, A-, B+, B-) may be configured in software, using inputs 6 and 7 on the S8 module.

The S8 module interfaces with both linear sensors and rotary encoders. One LED per channel indicates the state of the respective input.
