GE IC660TBA026

Summary

The GE IC660TBA026 is a 120 Volt AC (VAC) Triac Output Terminal Block Module for the GE Fanuc Series 90-30 Programmable Logic Controller (PLC) system. In simple terms, it’s a module that allows the PLC to turn industrial AC devices (like motors, solenoids, or lights) on and off.

1. Key Features and Function

Manufacturer: Originally part of the GE Fanuc automation portfolio. This product line is now under Emerson and is part of the Emerson Machine Automation Solutions family, though it’s still widely known and referred to as GE/GE Fanuc.
System: Designed for the Series 90-30 PLC rack.
Function: Discrete Output Module. It sends “ON” or “OFF” signals from the PLC’s CPU to field devices.
Output Type: Triac (Solid-State Relay).
- Advantages: Triacs are solid-state switches, meaning they have no moving parts. They offer faster switching speeds and longer life than mechanical relays. They are ideal for frequently switching AC loads.
- Key Trait: A Triac output allows a small amount of leakage current (typically ~2-3 mA) to flow even when the output is in the “OFF” state. This is a critical characteristic to be aware of during design and troubleshooting.
Voltage: 120V AC. This is the load voltage it is designed to switch.
Number of Channels: 16 isolated outputs. “Isolated” in this context means the outputs are grouped, typically in banks of 4 or 8, with a common connection for each group. You must check the datasheet for the specific grouping, as it affects wiring.

2. Physical and Electrical Specifications

Mounting: It is a terminal block module that plugs directly into a Series 90-30 PLC rack.
Points: 16 outputs.
Output Rating: Each output can switch up to 0.5 Amps continuous current.
Load Voltage: 120V AC (operates within a specified range, e.g., 85-132V AC).
Leakage Current: Typically < 3 mA (a crucial spec when driving sensitive devices like some proximity sensors or LEDs that might glow faintly when “off”).
Fusing: The module includes internal protection for each output channel.

3. Applications

This module is used in industrial control panels to control a wide variety of 120V AC devices, such as:

Motor starters and contactors (coils)
Solenoid valves
Indicator lamps and lighting
Heating elements
Small AC motors
