The Allen Bradley 1756-OA16 is a chassis-based, high-performance digital AC output module that serves as an interface between a programmable automation controller backplane and discrete field-level machinery. It provides 16 robust mechanically fused output channels, logically divided into two independent groups of 8 points per group to manage varying industrial field circuits simultaneously. Designed with advanced diagnostics, it supports both direct-connect and rack-optimized communications, enabling deterministic real-time state control, point-level fault monitoring, and proactive status updates.

(1) Digital Output Type: 120 / 240V AC type

(2) Digital Output Voltage Range: 74 V to 265 V AC

(3) Maximum Rated Current per Digital Output: 0.5 A maximum, per DO channel

(4) Maximum Rated Current per Module: 4 A maximum, per complete module

(5) Module Specific Functions: 16 mechanically fused outputs grouped into 8 points per isolated group

(6) Operating Temperature Range: 0 °C minimum to 60 °C maximum (32 °F to 140 °F)

(7) Storage Temperature Range: -40 °C minimum to 85 °C maximum (-40 °F to 185 °F)

Discrete AC Field Actuation:

Used to directly control high-power industrial alternating current loads such as motor starters, solenoids, indicators, and contactors.

Isolated Group Control:

Ideal for manufacturing lines that require different field power sources or separate isolation zones across the same 16-point hardware rack slot.

Heavy Industry Automation:

Deployed in demanding plant-floor architectures like water treatment, automotive assembly, and material handling where robust AC signal switching and fused loop protection are mandatory.
