Ground Master Monitor for 8 Tool Grounds, Ethernet, 24 V Input - Desco 770044

In semiconductor, disk drive and electronics manufacturing, proper grounding of process tools protects yield. The SCS Ground Master Monitor continuously monitors the path-to-ground impedance of eight metal tools and gives a visual and audible alarm as soon as a channel exceeds the selected limit between 1 and 20 ohms.

Key benefits

• 8 channels with test limit set by rotary switch from 1 to 20 ohms (default 10 ohms)
• EMI monitoring alarms on high-frequency noise on tool grounds that could cause EOS damage
• 7 to 24 VDC input terminals pair with voltage sources inside the machine, no adapter needed
• Ethernet link to the Static Management Program (SMP) for impedance and EMI voltage data
• Optical relay for connecting lights and buzzers
• NIST-traceable calibration, verified in place with the CTE701 Verification Tester

Applications

Ground monitoring of placement machines, dispensers, handlers and soldering equipment in semiconductor, flat panel and electronics manufacturing.

Standards

Meets the continuous monitor requirements of ANSI/ESD S20.20 in accordance with ESD TR53.
