10JT

High-density Signal Conditioners 10-RACK

THERMOCOUPLE TRANSMITTER

(field-programmable)
Functions & Features
• Accepting direct input from a thermocouple and providing two standard process signals
• Microprocessor based
• Field-programmable T/C type and temperature range
• Linearization
• Burnout protection
• High accuracy cold junction compensation
• Loop testing via hand-held programmer PU-2x
• Second channel output available at the front terminals and at the Standard Rack connector
Typical Applications
• Ideal for quick spare part
• High-accuracy cold junction compensation benefits narrow span measurements
• 0.1μA 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
