0076: Function Code (16-channel digital output, QBO type)

G01: Initial Hardware Version

Basic Information

Manufacturer: Emerson Process Management

Origin: United States

Form: Standard single-slot card, supports hot swapping

Weight: Approximately 0.40 kg

Installation: Ovation I/O Backplane (universal for 13A series)

Certifications: CE, UL/CSA, Class I Div.2

Status: Active mainstream digital output spare part, commonly used in power / chemical industries Function positioning

Output 24VDC source-type signals to drive on-site relays, contactors, solenoid valves, indicator lights, etc.

16 independent outputs, with optical isolation between channels, strong anti-interference

High-side switch (Source), directly providing 24VDC to the load

Channel-level overcurrent / short-circuit protection, fault self-diagnosis and reporting

Each channel has an LED status indicator light, facilitating on-site debugging and maintenance

Suitable for conventional switch quantity control scenarios, without external relays
