Product details

The Mitsubishi Q64TD is a 4-channel thermocouple input module for the Q-series PLC, with resolution down to 0.1°C on J-type thermocouples and a 20 ms per-channel sampling period. Each channel is independent with disconnection detection, and the module occupies 16 I/O points on the backplane. The module accepts standard thermocouple types per JIS C1602-1995, including B, R, S, K, T, E, J, and N, with resolution varying by type: 0.7°C for B, 0.8°C for R/S, 0.3°C for K/T, 0.2°C for E, 0.1°C for J, and 0.4°C for N.

Accuracy characterization

The per-channel accuracy follows a formula: accuracy (°C) = conversion accuracy + (temperature characteristics × use ambient temperature change) + cold junction compensation accuracy. The conversion accuracy is specified at an operating ambient of 25°C ±5°C; outside that range, add the temperature coefficient per 1°C change. Cold junction compensation accuracy is ±1.0°C, which forms the baseline uncertainty for all thermocouple measurements. The digital output is 16-bit signed binary, scaling measured temperature as 10 times the value to the first decimal place, with a range of -2700 to 18200.

Integration details

The module connects via an 18-point screw terminal block (M3 screws) for external wiring. Power draw from the 5 V backplane bus is 0.50 A. Insulation is via transformer between each thermocouple channel and the sequencer power supply, with a dielectric withstand of 1780 Vrms for 3 cycles.
