The MercuryiTC
• can accommodate thermocouple sensors with cold-junction compensation (CJC).
• can accommodate silicon-diode sensors (constant current supply).
• can detect short-circuit inputs, open-circuit inputs, and inputs that are shorted to ground.
• can store sensor calibration files.
• can automatically set range-limits from the calibration file.
The user does not need to set the zero or the span for calibrated sensors.
17.4 Heater outputs
Item Specification
Basic iTC - heater outputs.
Single fully-controlled 80 W output. Upgradeable
to 4 fully-controlled 80 W outputs.
Maximum output current. 2 A
Voltage compliance limit. 40 V
Load resistance range 20 ohms to 2500 ohms
Output resolution 16 bit
The output is filtered with co-wound inductors and decoupling capacitors.
The output is protected against short-circuits.
The MercuryiTC has a “dead-man’s-handle” timer that disables the heater outputs if the control
loop stalls.
17.5 PC interfaces
Item Specification
Serial interface RS232 + ISOBUS
Serial interface 2 USB
GPIB IEEE-488 (optional)
Ethernet 10/100 IEE802.3
