TEL 3D81-050026-V1 Printed Circuit Board
Product Manual：
TEL 3D81-050026-V1 is a digital signal acquisition PCB board for Tokyo Electronic Semiconductor Equipment, with simplified features:
1. Multiple digital channels, collecting signals from limit switches, door locks, and sensor switches
2. Channel optocoupler isolation to prevent high-voltage interference and signal backflow from damaging the motherboard
3. Partition independent wiring, separate strong and weak electricity, reduce signal crosstalk
4. Gold plated connectors, with stable contact and resistance to oxidation after repeated insertion and removal
5. Equipped with a built-in status indicator light, it provides a visual view of the on/off status of each channel
6. Multi layer metalized via with low signal transmission loss
7. Built in filtering circuit to filter electromagnetic clutter in the workshop
8. FR4 high-temperature resistant substrate, suitable for etching and coating machine environments
9. Reserve multiple test pads for quick fault diagnosis and troubleshooting
10. Equipped with overcurrent protection, single channel failure does not affect the entire board
11. Standardized card slot installation, convenient disassembly and replacement of cabinets
12. The silk screen markings are clear, and the channels and power terminals are easy to see at a glance
13. Reinforce the plate structure to resist continuous vibration and breakage of the machine
14. Compatible with EFEM and vacuum chamber safety interlock control
15. Original factory standard size, can be directly replaced with the same model without changing the wiring
TEL 3D81-050026-V1 printed circuit board has stable signal acquisition and is a core spare part for semiconductor wafer equipment I/O.
