GE IC660TBA025 | 6-Channel Analog Output Terminal Block | IC670MDL241K

GE IC660TBA025 Product Specification

Product Overview

The GE IC660TBA025 is a 6-channel analog output terminal block designed for GE’s Genius I/O platform, engineered to provide precise and reliable control of industrial field devices. As a critical component of the Genius architecture, this module converts digital signals from the PLC into analog current outputs (4–20 mA), enabling seamless integration with actuators, valves, and transmitters in process automation systems.

Integrated into the Genius system, the GE IC660TBA025 accepts a wide input voltage range (18–56 VDC) and delivers a continuous output current of 250 mA per channel, with an accuracy of ±0.15% at 25°C and a resolution of 6 µA17. It supports bus switching mode for redundant systems, ensuring uninterrupted operation in high-availability applications like power generation or oil refining. The module’s configurable features include output feedback checking, default mode programming, and CPU redundancy override, allowing technicians to adapt it to diverse control strategies79.

With a compact design (22.44 cm × 8.89 cm × 10.00 cm) and lightweight structure (0.45 kg), the GE IC660TBA025 fits seamlessly into GE IC660CHS007 racks, optimizing cabinet space. Its rugged construction—including a conformal coating and IP20 enclosure—supports operation in temperatures from 0°C to 60°C, with resistance to vibration (10–2000 Hz, 10 G rms) and humidity (5–95% non-condensing)79. Front-panel LEDs indicate channel status and fault conditions, simplifying troubleshooting, while built-in protection against overcurrent and short circuits safeguards connected equipment.

Technical Specifications

Main Features and AdvantagesPrecision Analog Control:
The GE IC660TBA025 delivers 4–20 mA outputs with ±0.15% accuracy, ensuring precise regulation of process variables like flow, pressure, or temperature. For example, in a chemical plant, it can control the opening of a control valve with 0.1% resolution, minimizing product waste during batch processing17.

Redundant System Support:
With bus switching mode, the GE IC660TBA025 automatically switches to a backup communication path in redundant Genius systems, maintaining control continuity during bus faults. This feature is critical in power plants, where downtime can lead to costly production losses79.

Configurable Output Feedback:
The module monitors output feedback signals and triggers alarms if values drop below 1.5 mA or exceed the 设定 range, enabling proactive fault detection. In oil refineries, this prevents damage to pumps by identifying blocked pipelines before system failure79.

Modular Design for Flexibility:
As part of the Genius I/O platform, the GE IC660TBA025 works seamlessly with modules like the GE IC660BBA104 (analog input) and GE IC660BBS102 (discrete I/O), allowing mixed I/O configurations in a single rack. This modularity reduces wiring complexity and installation time in automotive assembly lines89.

Rugged Industrial Performance:
A conformal coating and IP20 enclosure protect the GE IC660TBA025 from dust, moisture, and chemical vapors, ensuring reliability in harsh environments like steel mills or offshore platforms. Its wide temperature range (0°C–60°C) supports operation in both arctic and tropical climates79.

Application Areas

Manufacturing:

1. Controls robotic arm movements in automotive plants by providing 4–20 mA signals to servo drives, ensuring precise welding or painting trajectories.
2. Regulates conveyor belt speed in packaging lines by adjusting motor drives based on product flow rates.

Power Generation:

1. Modulates steam turbine valves by sending analog signals to hydraulic actuators, optimizing energy output based on grid demand.
2. Controls cooling water pumps in power stations by adjusting flow rates according to temperature readings from GE IC660BBA104

Oil and Gas:

1. Manages subsea wellhead pressure by actuating control valves in offshore platforms, maintaining safe operating conditions during production.
2. Regulates chemical injection systems in refineries to ensure consistent additive dosing for corrosion prevention

Water/Wastewater:

1. Adjusts chlorine dosage in treatment plants by controlling metering pumps, ensuring compliance with disinfection standards.
2. Operates sludge dewatering equipment by varying motor speeds based on moisture content detected by sensors.

Installation and Maintenance

Pre-installation preparations: Before installing GE IC660TBA025, verify the IC660CHS007 rack is properly grounded and the input voltage matches 18–56 VDC. Use AWG 14–22 wires for field connections, ensuring terminal block torque is 0.6 N·m. Connect the module to the Genius bus via the backplane and configure parameters using GE IC660HHM501H or PLC software, such as setting output ranges and enabling feedback checking79.

Maintenance suggestions: Perform monthly visual inspections of GE IC660TBA025’s LEDs—steady green indicates normal operation, while red signals channel faults. Clean dust from ventilation slots quarterly with compressed air to maintain cooling. Annually, use a multimeter to verify output accuracy (±0.15% at 25°C) and check for loose connections. Replace the module if output drift exceeds ±0.5% or if protection features fail to activate during testing79.
