B-4 Compact™ IO Isolated Thermocouple Module
User’s Manual Pub. 0300244-01 Rev. A
To prevent violation of channel-to-channel isolation:
• For multiple exposed junction thermocouples, do not allow the measuring
junctions to make direct contact with electrically conductive process material.
• Preferably use a single exposed junction thermocouple with multiple
ungrounded junction thermocouples.
• Consider using all ungrounded junction thermocouples instead of the exposed
junction type.
