Allen-Bradley 1746-OB16 SLC 500 Digital DC Output Module, 16 Points, 24V DC Source
Allen-Bradley 1746-OB16 is a 16-point digital DC output module for the SLC 500 family, sourcing 24V DC loads.
Overview
The module provides 16 sourcing outputs in one group, operating from 10-50V DC with a 24V DC nominal system. Signal delays are 0.1 ms on and 1 ms off at maximum resistive load, and each output tolerates a 3 A surge for 10 ms. On-state voltage drop is 1.2 V maximum at 0.5 A; minimum load is 1 mA and off-state leakage is 1 mA. The backplane draws 0.28 A at 5V DC with no 24V DC load, heat dissipation totals 7.6 W, and a removable terminal block is included.
