I/O expansion module RevPi MIO

analogindustrialcompact

In addition to the dedicated digital and analog I/O expansion modules, there is also an I/O module for Revolution Pi that has digital inputs/outputs as well as analog inputs/outputs. The RevPi MIO adds 8 analog inputs, 8 analog outputs and 4 digital channels to the Revolution Pi system. The digital channels can be individually configured via software either as digital inputs or digital outputs. Like all I/O modules, the RevPi MIO is protected against interference in accordance with the EN 61131-2 standard and can be operated at -20 °C to +55 °C ambient temperature. Analog Inputs and Outputs The 8 analog inputs and 8 analog outputs can be connected via the 28-pin terminal connector on the front of the module. Both the inputs and the outputs operate with 0 – 10 V. Variable switching thresholds allow the analog inputs to behave like digital inputs. The switching thresholds can be set for each channel. Each analog input is high impedance with a 100 kΩ input resistor and has a hardware filter with a cutoff frequency of 1.5 kHz. Additionally, each input is protected against ESD pulses by a protection diode. The analog outputs can also be configured to output a constant, predefined voltage. This allows the analog outputs to be used like digital outputs and logic levels up to 10 V can be used. Digital inputs and outputs In addition to its analog inputs and outputs, the RevPi MIO also features 4 digital channels. Each channel can be configured either as digital input or digital output via the Revolution Pi configuration tool PiCtory. Furthermore, the following operating modes can be set: PWM input, pulse measurements, GPI 24 V, PWM output, pulse output & GPO 24 V level output
