Description

Configured for discrete signal connection and field terminal interfaces in Genius I/O networks, the GE Fanuc IC660TBD023 (IC660TBD023 Terminal Assembly) provides direct physical/electrical execution. This 16-circuit discrete input and output terminal base supports DC-powered blocks, routing 24 VDC field signals to system backplane logic without external termination assemblies.

Backplane Bus & Deterministic Network Interfaces

The IC660TBD023 interface leverages deterministic serial bus messaging native to the Genius I/O architecture. Internal signal paths maintain backplane bus communication velocity across high-density I/O distributions, executing selectable input filter response times ranging from 5 ms to 100 ms. Channel-level diagnostics perform continuous hardware scanning for open wire anomalies, overtemperature limits, and internal output switch failures. The terminal assembly maintains 1500 VAC isolation between distinct blocks to prevent ground loops across field network segments.

Frequently Asked Questions

Q: What is the maximum allowable output current load on the IC660TBD023 terminal assembly?

A: Individual output circuits support up to 2 A continuous load. Total aggregate block current must not exceed 15 A at an ambient operating temperature of 35 deg C.

Q: How does the IC660TBD023 respond to momentary supply voltage interruptions?

A: The internal power regulation circuit provides a power supply dropout time of 10 ms, maintaining logic states and operational stability during brief DC power fluctuations.

Field Installation Guidelines

  1. Mount the terminal assembly on standard mounting rails or direct panels within a grounded industrial enclosure. Ensure clearance around the assembly to accommodate 68.8 W maximum thermal dissipation under full output loading.
  2. Route 24 VDC power lines (18 to 30 VDC operating range) to the dedicated terminal power contacts. Maintain clean DC input lines with maximum allowable ripple capped at 10%.
  3. Terminate 16-channel discrete field wiring to individual screw terminals. Observe polarity for sink input configurations and ensure signal shield drains connect directly to the central enclosure earth ground bar.
  4. Verify mechanical seating between the IC660TBD023 terminal base and the matching IC660T, IC660TB, or IC660TBD electronic module before applying power.
