The 2085-IT8/IT16-SC Expansion I/O modules support direct voltage (±50 mV
and ±100 mV) and direct Thermocouple (Type: J, N, T, K, E, S, R, C, B)
measurements. The module supports:
•
Eight analog input channels for the 2085-IT8-SC.
•
Sixteen analog input channels for the 2085-IT16-SC
•
The modules measure either voltage or provide data measurements of
temperature using thermocouple and CJ sensor voltage inputs for each
channel.
•
Direct voltage measurements. The low-drift precision resistor is not used,
and the channel accepts the voltage source directly.
•
Direct thermocouple. For both modules, two cold junction sensors are
available to be placed at the top and bottom of each terminal block. The
module measures thermocouple and CJ Sensors voltages and converts
the results to a temperature reading.
•
Two physical Cold Junction Compensation sensors (one at top, one at the
bottom of each terminal block), and two CJC profiles (averaged and
distributed) are supplied.
•
Four data formats.
•
Four filter frequency selections.
•
Real-time Terminal Block temperature updating when the channel is
enabled.
•
Range scaling of input data.
•
Alarm notification on each channel’s status:
-
Over or under range detection (from user-defined values).
