DM681x series of Digital I/O dataModules® February 1, 2015 RTD Embedded TechnologiesInc — No Comments RTD Provides a wide array of Digital I/O controller modules with features that range from pulse width modulators, incremental encoder interfaces and user programmable timer/counters. The modules offer bit or port programmable, diode protected Digital I/O lines. Advanced digital interrupts offer event and match mode customizable interrupts. Three 16-bit timer/counters can be used to divide down the on-board 8 MHz clock for customizable sampling rates. Nine independent pulse width modulation channels provide an adjustable frequency and variable duty cycle outputs with differential and singled-ended options. Each channel provides 8 bit resolution and can be enabled or disabled independently. Three quadrature encoder diode protected inputs for rotary or linear position encoders. Index input resets the counter to zero. Pseudo-differential mode and input filter increases noise immunity. Up to 32-bit counter width provides large range.
