GE IC660TBA105 PLC Terminal Assemblies

The GE Fanuc IC660TBA105 serves as the primary IC660TBA105 Terminal Assembly utilized to execute analog output field terminations across Genius I/O platforms. Configured specifically for six current-source outputs, it provides direct physical interfaces and channel routing for 115 VAC and 125 VDC operating loops.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

The GE Fanuc IC660TBA105 terminal assembly ensures deterministic backplane bus communication velocity across Genius I/O networks. Featuring full pass-through routing for handheld monitor configuration routines and PCIM/QBIM bus controller connectivity, the hardware maintains 0.15% full-scale output accuracy at 25 deg C with an update frequency of 25 ms. The terminal backplane design allows module maintenance and firmware flash compatibility without disrupting active serial loop signal transmission or neighboring block addresses.

Frequently Asked Questions

Q: What is the power supply dropout immunity threshold for the IC660TBA105?

A: The IC660TBA105 terminal assembly accommodates a power supply dropout time of 1 cycle under AC operation and 10 ms under DC operation without faulting output states.

Q: Can fault reporting be disabled on individual output channels?

A: Yes. Fault reporting features on the IC660TBA105 can be enabled or disabled independently for specific circuits using a Genius handheld monitor.

Field Installation Guidelines

1. Mount the IC660TBA105 securely onto the panel sub-plate, verifying that structural grounding metal-to-metal contacts meet chassis isolation specs (1500 VAC block-to-block rating).
2. Maintain environmental operating limits between 0 to 60 deg C and 5% to 95% relative humidity (non-condensing).
3. Connect field loop conductors to specified current-source output terminals, keeping conductor runs separated from high-voltage AC lines to prevent inductive coupling.
4. Torque terminal screws to 0.8 Nm to 1.2 Nm and ensure signal line shields are grounded at a single point to prevent ground loop noise on current-source outputs.
