Installation and Operation Notes:
The 1794-AENTR is directly mounted to a DIN rail. Ensure the installation point is free from excessive vibration and shock; the module is rated for operating vibration up to 5 g and shock up to 30 g. An external power supply with a nominal voltage of 24 V DC must be connected to energize the module. The acceptable voltage supply range is 19.2–31.2 V DC, including up to 5% AC ripple. Recommended conductor wire size for module connections is 0.33–3.31 mm² (22–12 AWG), stranded copper wire with insulation rated at 75 °C (167 °F) or higher and a maximum insulation thickness of 1.2 mm (3/64 in).
