Product Description

Overview

The 216AB61 is a high-performance Binary (Digital) Output Module designed for the UNITROL 6000 excitation systems and REG 216 generator protection series. It converts logic-level control signals from the central controller into robust electrical outputs capable of driving actuators, relays, and status indicators. This module ensures precise execution of control commands, supporting fast interlocks, trip signals, and critical automation tasks in power plant environments.

Key Features

• High Galvanic Isolation: Each output channel provides up to 2.5 kV rms isolation, protecting sensitive electronics from voltage surges, ground loops, and electrical noise.

• Dual Voltage Compatibility: Supports both 24 V DC and 120 V AC outputs, allowing integration with diverse field devices without additional relays.

• Rapid Switching: Minimal propagation delay ensures real-time execution of control commands, essential for generator protection and safety-critical operations.

• Onboard Diagnostics: Integrated LED indicators and feedback to the central controller enable quick fault detection, including short circuits, open circuits, or abnormal output levels.

• Rugged Industrial Design: High EMC immunity, durable construction for wide temperature ranges, and flexible DIN rail or subrack mounting.

Technical Specifications

Applications

The 216AB61 is widely used in power plants for excitation system control, generator protection, and industrial automation. It drives relays, solenoids, valves, and indicators, supporting fast response sequences and secure actuation in safety-critical processes.
