GE IC660TBA023 Terminal Assembly

This terminal assembly connects field wiring to Genius I/O blocks. It accepts discrete input signals from switches and sensors. You will mount this unit directly on DIN rails.

Key Technical Specifications

The IC660TBA023 provides sixteen discrete input channels for 24V DC signals. Each channel includes an LED indicator for visual status confirmation. The assembly also features removable terminal blocks for easy wiring replacement.

Hardware Architecture and Signal Conditioning

The IC660TBA023 uses thirty-two current-limiting resistors for each input channel pair. Sixteen red LEDs light up when the corresponding input becomes active. A 24-pin male connector links this terminal assembly to the Genius I/O block. The passive design contains no active semiconductor components.

Interface and Connectivity

Four 4-position removable terminal blocks accept field wiring from sensors. Each terminal block features screw clamps for secure wire retention. A 24-pin ribbon cable carries input signals to the main I/O block. You can replace individual terminal blocks without rewiring the entire assembly.

Practical Installation Notes

Snap this terminal assembly onto a standard 35 mm DIN rail. The IC660TBA023 requires 5 cm clearance for LED viewing and access. Always use copper wires with 0.5 to 2.5 mm² cross-section. Connect the common terminal of each input group to the same 24V DC supply return.
