In stock

Product Introduction:
The TB43300AF14 is a high-density termination board for GE Fanuc Series 90-70 PLC systems. The “43300” designation indicates a 32-channel board with a specific configuration optimized for high-current outputs or mixed analog/digital I/O. This revision 14 board represents the latest iteration of this termination board family, featuring improved component quality, better thermal performance, and enhanced diagnostic capabilities compared to earlier revisions. It serves as the physical gateway between the PLC’s internal bus and the external world, ensuring that every signal is properly conditioned, protected, and terminated before reaching the sensitive CPU logic.

Technical Specifications:
Board Type: Termination Board (TB)
Revision: 14 (AF14)
Channel Count: 32 channels (configurable as 16 input / 16 output, or 32 input, or 32 output)
Output Current: Up to 2 Amps per channel (higher than standard TB43225)
Input Voltage: 24V DC, 48V DC, 120V AC, 240V AC
Output Voltage: 24V DC, 120V AC, 240V AC (relay or transistor)
Isolation: 1000V RMS channel-to-channel isolation
Terminal Blocks: High-density removable terminal blocks (3.5mm pitch)
Power Consumption: Approximately 3 Watts
Form Factor: 3U Eurocard

Functional Features:
High-Current Outputs: Capable of driving larger loads like contactor coils, solenoid valves, and indicator lamps directly without external relays.
Mixed I/O Support: Can be configured with both input and output channels on the same board, reducing the total number of slots required.
Enhanced Diagnostics: Revision 14 includes per-channel current monitoring, allowing the CPU to detect a partially failed output (e.g., a solenoid coil that is shorted but not fully open).
Improved Thermal Design: Better heat dissipation allows the board to operate at higher ambient temperatures without derating.
Fail-Safe Outputs: Configurable to default to a safe state (energized or de-energized) upon loss of CPU communication.

Application Scenarios:
Heavy Machine Control: Drives large contactors for motor starters, compressor unloads, and hydraulic power unit solenoids.
Process Skid Control: Interfaces the PLC to field valves, pumps, and heaters in skid-mounted process packages.
Building Automation: Controls HVAC dampers, lighting circuits, and fire alarm interfaces in commercial buildings.
Material Handling: Manages sortation systems, lifts, and gates in warehouses and distribution centers.
