UTLH21
In automotive manufacturing, the TOSHIBA UTLH21 is widely deployed in robotic welding cells, where it converts PLC control signals into precise power outputs for weld guns. By regulating current flow with ±1% accuracy, it ensures consistent weld quality across thousands of cycles, reducing rework and material waste. A major automaker in Japan reported a 15% reduction in weld defects after upgrading to the UTLH21, attributing the improvement to the module’s stable power delivery.
- TOSHIBA UTLH11 – A compact, lower-current variant (5A max) ideal for light-duty applications like conveyor belt controls.
- TOSHIBA UTLH31 – A high-power version (20A continuous) designed for heavy machinery such as industrial presses.
- TOSHIBA TCXH08 – A PLC expansion module that pairs with the UTLH21 for enhanced logic control in complex systems.
- TOSHIBA VFS15-4075PL – A variable frequency drive (VFD) seamlessly integrated with the UTLH21 for motor speed regulation.
- TOSHIBA TLP181 – An optocoupler module that enhances signal isolation when used with the UTLH21 in high-noise environments.
