Kawasaki 1TB-92 50999-1481 PCB Board – Robot Controller Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Kawasaki 1TB-92, also designated by part number 50999-1481, is a printed circuit board designed for installation in Kawasaki C, D, and E series industrial robot control cabinets. Operating as part of the Kawasaki Industrial Robot Controller Components family, this board functions within a modular rack chassis to route internal controller bus signals and manage power distribution. Equipped with a multi-pin backplane edge header interface, the module connects directly into control cabinet rack slots, serving as an internal routing assembly across automotive manufacturing, material handling, automated packaging, and aerospace assembly applications.
Installing a replacement 1TB-92 module requires attention to physical alignment and proper safety protocols. Before replacing the unit, power to the control cabinet must be locked out and tagged out, and technicians must maintain electrostatic discharge (ESD) handling precautions to prevent damage to sensitive components. Technicians must inspect and set all physical jumper headers and configuration switches on the spare card to match the layout of the original board. Software communication and parameter operations interface through tools including KC WinTP, K-ROSET software, and the standard teach pendant interface. ABC Industrial Parts can support service teams with verified replacement hardware to restore equipment operation efficiently.
System state monitoring and initial troubleshooting are facilitated by integrated on-board diagnostic LEDs, which display power supply presence, active bus communication, or internal board fault conditions through solid, flashing, or unlit states. Further diagnostic data is available by inspecting the AS Language error history log or viewing the teach pendant hardware diagnostic screen. When internal component or signal failures occur, field repair of the PCB assembly is generally not practical. Installing a tested replacement module from ABC Industrial Parts offers a direct solution to bring the robot controller back into active production.

Programming and Configuration
The Kawasaki 1TB-92 board interfaces with standard engineering and setup tools used across Kawasaki robot automation systems. System parameters, motion routines, and internal signal monitoring are accessible using AS Language commands and diagnostic screens on the teach pendant. The unit is fully compatible with KC WinTP and K-ROSET offline programming and simulation environments.
Physical configuration of the 1TB-92 is executed via jumper headers and selector switches located on the circuit board itself. When preparing a spare card for service in a C, D, or E series cabinet, maintenance personnel must verify that all jumper configurations match the original hardware to maintain correct bus address routing and signal integrity.
Communication and System Integration
Connection to the controller chassis is established through a multi-pin backplane edge connector interface. Designed for rack slot-in installation, the board seats directly into the backplane bus inside the control cabinet, providing direct physical and electrical interconnection across internal system buses.
Within the control cabinet structure, the 1TB-92 module provides internal controller bus signal routing and power distribution. This multi-pin edge connection ensures reliable low-noise signal paths between central processing units and distributed controller sub-assemblies.
Diagnostics and Status Indication
Integrated on-board LED indicators provide rapid visual assessment of board operational status inside the cabinet. These status LEDs illuminate, flash, or remain off to indicate primary power presence, active backplane bus communication, or internal fault conditions.
Comprehensive diagnostic routines can be performed using software tools and controller interfaces. Service personnel can view real-time hardware status on the teach pendant hardware diagnostic screen or analyze historical error events via the AS Language error log.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| LED Status Indicators | Solid / Flashing / Off | Indicates power supply presence, active bus communication, or internal board fault conditions |
Replacement and Spare Part Considerations
Because the Kawasaki 1TB-92 is a discontinued component, sourcing tested spare boards is essential for maintaining operational readiness on legacy C, D, and E series controller cabinets. The modular rack slot-in design allows direct physical replacement without chassis modification.
Prior to removing or inserting the board, complete system lockout and tagout procedures must be executed to ensure safety. Technicians should observe electrostatic discharge (ESD) protections to prevent damage to onboard integrated circuits. Matching all physical jumper header settings between the replacement board and the original unit is required before restoring power to the cabinet.
