Allen‑Bradley 1790D‑T0A6 Output Base Module – 6 Point AC Output, Compact I/O

1790D-T0A6 120V AC 6 Output Base Module

Brand: Allen‑Bradley | Series: Compact I/O 1790D | Type: Digital Output Module

This module delivers six nonisolated AC outputs for machine control. It supports 85…132V AC loads with a max current of 0.5 A rms per point. The design ensures fast operate time (≤1 ms) and release within ½ cycle + 1 ms. Ideal for valve actuators, pilot lights, and motor starters in industrial systems.

Frequently Asked Questions

• Can I use this with 230V AC? No, load voltage range is 85…132V AC only.
• Is it isolated from field power? Field power is non‑isolated; I/O to logic is photocoupler isolated.
• What fuse do I need? 1 A, 250V normal blow fuse per point.
• How many outputs share a common? 6 points share one common (6 points / 6 COM).
