Thermocouples generate low-level voltage signals corresponding to temperature differences, while millivolt input capability allows the module to process compatible low-level voltage signals.\u003c\/p\u003e\n\u003cp\u003eThe supported thermocouple types are B, E, J, K, R, S and T. These sensor types have different temperature characteristics and calibration curves, so the configured sensor type must match the thermocouple connected to each input channel.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAnalog Output Configuration\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eIn addition to its two measurement inputs, the 1771-NB4T provides two 0-25 mA output channels. This combination of input measurement and analog output capability allows the module to handle both signal acquisition and current-signal output within the PLC-5 system.\u003c\/p\u003e\n\u003cp\u003eThe 0-25 mA range should be distinguished from the more common 4-20 mA instrumentation range. The actual output scaling, connected load requirements and control configuration should be verified against the applicable technical documentation before integration.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003ePLC-5 System Application\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe 1771-NB4T is intended for PLC-5 system configurations requiring thermocouple or millivolt signal acquisition.
