The Allen-Bradley 1746-NI16V is a 16-channel high-density analog input module for the SLC 500 family, software-configurable to accept voltage signals on all channels. It provides sixteen voltage-input channels with per-channel configuration and status indication, and uses two common terminals for field wiring. As a voltage-input module (NI16V), it supports input ranges around ±10 V DC, and is powered from the SLC 500 backplane with a documented backplane current draw of 125 mA at 5 V (75 mA at 24 V).
