PS-482/484/488 Slug Detector[ ※Specification change after March 1, 2025 ]
Description
The Slug Detectors PS-482/484/488 are designed for detecting slugs, double piles driving, and so on, during automatic press working and for outputting stop signal to the press in case of abnormalities.
It reads a signal from Eddy current proximity sensor installed on the mold for the press and calculate the displacement by a microcomputer. If the displacement exceeds the limit, it outputs the stop signal to the press.
Since Ethernet is supported, the PS-482/484/488 can be connected to personal computer (PC) and PLC.
Features
The PS-482/484/488 have the following additional features together with those of our PS-462/464.
- Added functions helpful for detection
- - The LCD panel displays sensor waveforms.
- - Sensors can be connected up to eight (8) channels.(PS-488)
- - Unevenness calculation and multiple detection are available.
- Functions helpful for production control
- - Up to 99 patterns can be Stored.
- - Up to 1000 error histories and displacement for four strokes before and after the error can be saved.
- - Patterns can be recalled by ID tags. (Options)
- Ethernet supported
- - The contents of setting can be displayed in HTML format.
- - UDP protocol and Telnet protocol enable various settings and operations.
- - FTP protocol enables to output the displacement data during press working.
