Connections to the Analog Inputs are made through 5-pos terminal block (A4-TB3). The terminal block is removable to simplify wiring. Terminal connections are labeled along the edge of the Auxiliary I/O Board next to terminal block (A4-TB3). The Analog Inputs are NOT isolated and must be referenced to the negative(-) dc bus.


  1. De-energize and lock out all ac and dc voltages to ATevo.
  2. Allow internal voltages to dissipate and verify with a voltmeter.
  3. Remove safety shield.
  4. Route remote analog inputs to the Auxiliary I/O Board (A4) through an unused enclosure knockout.
  5. Connect signal wiring (#22-14 AWG) to appropriate terminals (A4-TB3) of the Auxiliary I/O Board.
  6. Strip each wire 0.25in / 6.4mm, and tighten terminal screws.
  7. Replace the safety shield.
  8. Re-energize ATevo.


  • Analog Inputs are rated at 0-10Vdc.
  • Terminal block is compression type and accepts #22-14 AWG.
  • All Analog Inputs (AN1, AN2, AN3, AN4) must be referenced to the ATevo negative(-) bus voltage (COM) terminal.
