Multiplexed Analogue Input Signal Conditioning Board SCB9212

The Hytec SCB9212 is a small signal conditioning board used to route 16 channels from rear panel SCSI connectors to Industry Pack I/O in the IOC 9010.

FEATURES

• 1 group of 16 analogue channel pairs
• Allows use of PT100 or thermocouple DIN Rail Board (8913-P or T) with IP-MADC-8403
• 16 channels of differential filters condition 8403 inputs
• Differential mode
• 16 differential channels multiplexed as two groups of eight for reading PT-100s or thermocouples via the 8913-T/P.
• CAL signal from 8403 used to select multiplexer input group.
• Requires external 9912 DC-DC Converter to provide 5V to +/-12V isolated power
• 1 signal pair for External Trigger
• 1 signal pair for External Clock
• Analogue Ground connections
