PLC-5 Thermocouple Signal Acquisition
The 1771-NT2 provides thermocouple and millivolt signal conversion for PLC-5 control systems. The module accepts eight analog input channels and converts temperature-related voltage signals into digital data values transferred through the 1771 chassis backplane.
The module supports multiple thermocouple input types including B, C, E, J, K, N, R, S, and T configurations. High-resolution conversion parameters vary according to the selected thermocouple type and input measurement range.
The 1771-NT2 uses PLC-5 backplane bus communication for controller data exchange. The module supports BDC and Natural Binary data formats for compatibility with PLC-5 processor configurations and I/O addressing structures.
Industrial Control Signal Compatibility
The 1771-NT2 integrates isolated analog input processing with PLC-5 I/O density scaling requirements. The isolated input design separates field thermocouple wiring from internal logic circuits to reduce electrical interference during temperature measurement.
The module uses PLC-5 deterministic backplane communication rather than Ethernet-based field networking. System integration requires correct rack addressing, slot configuration, and controller data table mapping.
Firmware flash compatibility is not specified for this module generation. Hardware operation depends on PLC-5 processor compatibility and correct module configuration within the 1771 chassis environment.
Frequently Asked Questions
Q: How many thermocouple input channels are available on the 1771-NT2?
A: The module provides eight isolated thermocouple/millivolt input channels.
Q: Which thermocouple types can be connected to the 1771-NT2?
A: The module supports Type B, C, E, J, K, N, R, S, and T thermocouple inputs.
Q: What backplane current does the 1771-NT2 require?
A: The module requires 1.5 A from the PLC-5 1771 chassis backplane supply.
Field Installation Guidelines
Install the 1771-NT2 module in a compatible 1771 I/O chassis slot and verify slot keying before insertion. Connect thermocouple wiring through the approved 1771-WH wiring arm and confirm correct polarity for each thermocouple input channel.
Route thermocouple signal cables separately from power conductors, motor wiring, and high-frequency switching circuits. Use appropriate shield grounding practices according to site electrical standards to reduce noise coupling.
The module is open-type equipment and requires installation inside an enclosure suitable for the operating environment. Maintain environmental conditions within the specified operating temperature and non-condensing humidity limits.
Verify thermocouple type configuration, PLC-5 data table mapping, and BDC or Natural Binary format selection before system commissioning.
