15TS
Dual Channel Input/Output Isolators 15-RACK
THERMOCOUPLE CONVERTER
Functions & Features
• Accepting direct input from a thermocouple and providing a standard process signal
• Linearization
• Burnout protection
• High-accuracy cold junction compensation
• 2 channels available; accomplishing economical and space-saving multi-input processing
Typical Applications
• High-accuracy cold junction compensation benefits narrow span measurements
• 0.1 μA burnout sensing enables long distance transmission with minimum offset drifts
• Electric furnace (isolation)
• No burnout type can connect to a single T/C in parallel with a recorder
