GE IC660TSA100 Terminal Assembly | 40 Positions, 10A, NEMA 12

Core Function of This Terminal Assembly

The GE IC660TSA100 provides field wiring connections for Genius I/O blocks. This terminal assembly interfaces between field devices and the electronic I/O module. It distributes power and signal connections to all input and output channels. Consequently, the unit simplifies installation and maintenance of industrial control systems.

Physical Dimensions and Enclosure Design

This terminal assembly measures 225 mm in total height. Its width reaches 128 mm for a standard Genius block footprint. The unit depth stands at 65 mm including the wiring cover. You will find a NEMA-rated thermoplastic housing for harsh environments. The GE IC660TSA100 weighs approximately 0.8 kilograms for panel or DIN rail mounting.

Terminal Configuration and Channel Capacity

The GE IC660TSA100 provides 40 screw-type terminal positions. These terminals serve up to 16 input channels and 12 output channels. The assembly also includes terminals for field power and common returns. Each terminal accepts wire gauges from 0.2 to 2.5 mm². A built-in labeling area allows user-defined channel identification.

Electrical Ratings and Connection Details

This terminal assembly handles up to 250 V AC continuous voltage per terminal. Each terminal carries up to 10 A of continuous current safely. The assembly includes separate terminals for the I/O block’s logic power. A dedicated earth ground terminal connects the shield drain wire. The unit also provides fuse holders for each output group protection.

Interface Connector and Block Mounting

The GE IC660TSA100 mates directly with the Genius I/O electronic block. A 50-pin male connector links the terminal assembly to the I/O module. Four mounting screws secure the electronic block to the terminal assembly. The unit also includes two DIN rail clips for panel-free installation. A removable wiring cover protects connections from dust and debris.

Isolation and Wiring Organization

This terminal assembly provides channel-to-channel isolation through physical separation. The housing design creates barriers between adjacent terminal screws. Color-coded terminal blocks distinguish input, output, and power connections. The assembly routes field wiring neatly to prevent signal cross-talk. A separate terminal section handles the 24 V DC logic supply to the I/O block.

Environmental Sealing and Protection

The GE IC660TSA100 meets NEMA 12 and IP54 environmental ratings. This sealing protects internal connections from dust and water spray. The terminal assembly operates reliably from -20°C to +60°C ambient. A silicone gasket seals the interface between the terminal and electronic block. The cover uses a latching mechanism that requires no tools for access.

Installation and Wiring Notes

You must mount the terminal assembly on a grounded DIN rail first. Then, connect all field wiring before attaching the I/O electronic block. Always tighten each terminal screw to the specified torque of 0.56 Nm. The cover should snap closed completely for proper environmental sealing. Regular inspection of terminal screws prevents loose connections from vibration over time.
