GE 369B1874G0019 Digital Output Board 16-Channel

GE 369B1874G0019 Digital Output Terminal Board Product Introduction

The GE 369B1874G0019 digital output terminal board serves as a critical interface between control processors and field devices. This module converts low-level logic signals into high-power switching actions, making it essential for turbine control, generator excitation, and system protection applications. Its rugged design ensures reliable performance in demanding industrial environments.

Specifically, the 369B1874G0019 provides 16 independent relay-based output channels. Each channel handles both AC and DC loads, offering flexibility for various field actuators including solenoids, contactors, alarms, and motor starters. The board's optical isolation per channel protects sensitive control electronics from voltage spikes and electrical noise originating from field equipment.

Technical Specifications

The GE 369B1874G0019 delivers 16 digital output channels with relay-based switching architecture. It supports contact ratings of 5A at 250VAC and 5A at 30VDC, accommodating a wide range of industrial loads. The board achieves a maximum switching frequency of 10 operations per second with a response time of 15ms for both operate and release actions.

Isolation ratings include 1500VAC between channels and the system, ensuring safety and signal integrity. Operating voltage is 24VDC with ±10% tolerance. The board features per-channel LED indicators that display ON/OFF status for quick visual diagnostics. Additionally, a conformal coating protects the PCB from moisture and contaminants in harsh industrial settings.

System Compatibility

The 369B1874G0019 integrates with multiple GE control platforms, including Mark VIe, EX2100e, OC4000E, and OC6000E systems. This broad compatibility makes it suitable for both new installations and retrofit projects across GE's turbine and excitation product lines. The board supports both simplex and redundant configurations, enhancing system availability for critical applications.

Mechanical and Environmental Parameters

• Mounting: Panel or rack mount within standard GE control cabinets

• Operating Temperature: -30°C to +65°C

• Storage Temperature: -40°C to +70°C

• Humidity: 5% to 95% non-condensing

• Conformal Coating: Yes, for environmental protection

• Dimensions: Standard GE turbine control footprint

Installation Guidelines

Installing the 369B1874G0019 follows a straightforward process. First, mount the board securely within the control cabinet using the standard rack-mount configuration. Next, connect the 24VDC power supply to the designated terminals, verifying correct polarity. For field wiring, use the removable screw terminals to connect each output channel to its corresponding actuator device.

When wiring AC loads, ensure that the contact rating of 5A at 250VAC is not exceeded. For DC loads, maintain the 5A at 30VDC limit. Additionally, route field wiring away from sensitive analog signals to minimize electromagnetic interference. The onboard overvoltage suppression and short-circuit protection provide an extra layer of safety during installation and operation. Finally, apply power and verify that the LED indicators reflect the correct output states from the control system.
