Description
NORCONTROL
NN-823
ERROR DETECTION VALVE DRIVER
PCB CARD
HE-220285B
The Norcontrol NN-823 is a printed circuit board card designed to perform error detection and valve driver functions within marine control systems. Mounted within an automation cabinet or control panel, this PCB interfaces with valve actuator circuits to monitor output signals, detect fault conditions, and drive valve operations as commanded by the system controller. As a core component in shipboard automation architecture, it plays a critical role in maintaining reliable control over fluid handling and process management onboard. Proper operation of this card directly supports the integrity of automated valve sequences, making it an essential element in the overall control loop.
Key Features
✓ Performs error detection and valve driver functions, providing both control output and fault monitoring within the same PCB assembly.
✓ Specific electrical ratings, response times, and dimensions are subject to confirmation based on system configuration and installation context.
✓ Designed for use within Norcontrol automation systems; compatibility with specific panels or controllers should be verified against the vessel’s system documentation.
✓ Intended for installation within enclosed control cabinets in a dry, protected environment typical of engine control rooms and automation spaces.
✓ Replacement of this card requires careful handling of static-sensitive components; system recalibration or configuration checks may be required following installation.
Marine Applications
✓ Automated valve control systems aboard cargo vessels, tankers, and bulk carriers requiring precise actuator management.
✓ Engine room automation panels where valve sequencing and fault detection are integral to safe machinery operation.
✓ Integrated bridge and machinery control systems utilising Norcontrol automation platforms.
✓ Ballast, fuel, and cooling water management systems that rely on automated valve driver circuits for remote operation.
✓ Offshore support vessels and platform supply vessels fitted with centralised automation systems requiring modular PCB-based control.
Why Marine Engineers Choose
Marine engineers working with Norcontrol automation systems select the NN-823 PCB card because it combines error detection and valve driving capability in a single, modular board — simplifying fault diagnosis and reducing system downtime during maintenance.
Ideal For
