VT2516A | VT2516A FPGA

Digital Module

The VT2516A module is connected to up to 16 mainly digitally used I/Os of an ECU, i.e. for signals with 2 states. In real vehicles for example, coding connectors, switches or signal lamps may be connected to these pins. This module is also available as a variant (VT2516A FPGA) with user programmable FPGA.

Functions for Each Channel

  • Various signal paths to the original sensor or the original actuator are switched via relays and are connected to a bus bar. The relays may be used, for example, to disconnect the line (broken wire simulation).
  • Relay for short circuit between an input line and ground or battery voltage
  • Relay for a connected external load, pull-up or pull-down resistor
  • Sampling of a digital input value with configurable voltage threshold
  • Determination of PWM signal parameters (frequency and duty cycle)
  • Voltage measurement with calculation of instantaneous and average values
  • Digital output with adjustable high and low levels
  • Autonomous output of a bit stream loaded into module
  • Generation of a PWM signal
