Description

The ABB 216NG62A (HESG441634R1) is a specialized control and protection module from the Procontrol P13 Decontic series. It is engineered for high-reliability industrial automation, serving as a central logic processor and protection unit for medium voltage motors. This module facilitates critical signal processing, electrical measurement interfacing, and protective relaying for three-phase asynchronous and synchronous motors operating in the 3 kV to 6 kV range.

Features

• Integrated motor protection including differential, overcurrent, negative-sequence, earth fault, and thermal overload functions.
• Supports real-time monitoring of motor acceleration, inrush current, and stall conditions.
• Configurable current transformer (CT) inputs for 1 A or 5 A secondary currents.
• Provides trip, alarm, and ready signaling via relay output contacts.
• Designed for integration into ABB Symphony, AC 800F, and AC 900F control architectures.
• Robust construction with IP54 front panel protection for harsh industrial environments.

Applications

• Power Generation: Management of high-capacity pumps, fans, and turbines.
• Steel and Rolling Mills: Control of induction motors for heavy metal-shaping machinery.
• Heavy Manufacturing: Continuous operation monitoring for crushers, grinders, and conveyor drives.
• Chemical and Water Treatment: Reliable motor protection for critical process infrastructure.

Technical Specifications

Installation Guidelines

• Power Down: Ensure all primary and auxiliary power sources are disconnected from the cabinet before module insertion or removal.
• ESD Protection: Always wear a grounded anti-static wrist strap when handling the board to prevent damage to sensitive internal components.
• Inspection: Visually inspect backplane connectors for bent or damaged pins prior to installation.
• Mounting: Designed for 1/4 x 19-inch rack or panel-mount configurations.
• Environment: Ensure adequate ventilation to maintain operating temperatures within the specified range.
