I/O modules

Product Overview

The GE IC660TSD021 terminal assembly provides a dedicated wiring interface for the Genius I/O system. This unit consolidates field device terminations for both discrete and analog signal types. It mates directly with the corresponding I/O block through a keyed connector system. The assembly simplifies troubleshooting with clearly marked terminal designations for each channel.

Technical Specifications

Mechanical Layout and Dimensions

This terminal assembly measures 11.5 centimeters wide and 4.8 centimeters deep. Its slim profile allows installation in shallow enclosures with limited clearance. The unit arranges twenty terminals in two parallel rows for intuitive wiring access. Weighing just 0.18 kilograms, this assembly adds minimal weight to the overall system.

Connection Interface Details

The GE IC660TSD021 uses a 20-position keyed header for connecting to the I/O block. Each terminal receives solid or stranded copper wire ranging from 14 to 22 AWG. The screw-clamp mechanism provides reliable gas-tight connections that resist oxidation over time. A transparent cover protects the wiring area while allowing visual inspection of each termination point.

Electrical Characteristics and Ratings

This assembly handles 10 amperes continuously through each terminal at 250 volts AC. The contact resistance remains below 5 milliohms for consistent signal transmission. Dielectric strength exceeds 1,500 VAC between adjacent terminals for safety assurance. Furthermore, the terminal block design maintains insulation coordination per IEC 60664-1 requirements.

System Integration with Genius I/O

You connect this assembly directly to the Genius I/O block using the provided ribbon cable. The GE IC660TSD021 supports both sourcing and sinking field devices without additional adapters. Its terminal numbering corresponds to the I/O channel mapping for error-free installation. This straightforward interface reduces commissioning time substantially for new system startups.

Environmental Endurance

This terminal assembly operates reliably between 0°C and 60°C ambient temperature. It withstands 95% relative humidity without performance degradation. The UL94 V-0 rated housing provides excellent resistance to flame propagation. Therefore, this unit suits demanding factory environments, including metal stamping and chemical mixing facilities.

Application Flexibility

Engineers use this assembly with analog signal conditioners, relay outputs, and sensor inputs. It accommodates both AC-powered devices and DC control circuits within its ratings. The GE IC660TSD021 also serves as a convenient distribution point for fieldbus terminations. Its universal design supports most industrial field wiring scenarios effectively.
