Allen-Bradley 1758-OB16E Digital Output Module

The Allen‑Bradley 1756-OB16E is a 16‑point DC digital output module for ControlLogix controllers, delivering two isolated groups of eight electronically fused outputs that switch loads from a 10–31 VDC supply and connect via a 20‑pin removable terminal block. As part of the 1756 ControlLogix I/O family, it plugs into the backplane of a ControlLogix chassis to provide direct DC output control for devices such as relays, contactors, and other DC loads in industrial automation environments. The module is designed for Series A installations and is specified for operating temperatures from 0 to 60 °C with nonoperating temperatures from -40 to 85 °C, humidity 5–95% noncondensing, and rugged industrial ratings including 2 g vibration (10–500 Hz) and 30 g operating/shock (50 g nonoperating). On the physical side, it weighs about 0.322 kg and uses a 20‑pin terminal interface to support wiring of all 16 channels. The OB16E’s electronically fused outputs provide per‑channel protection to help guard the controller and wiring network against faults, making it suitable for demanding applications in manufacturing equipment, packaging lines, and material handling where reliable DC switching is required.
