Typical Applications
R: 24 V DC
• High-accuracy cold junction compensation benefits narrow
span measurements
(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)
• 0.1 μA burnout sensing enables long distance
transmission with minimum offset drifts
• Electric furnace (isolation)
[3] OPTIONS
Burnout
blank: Upscale burnout
/BL: Downscale burnout
/BN: No burnout
• No burnout type can connect to a single T/C in parallel
with a recorder
