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. ## Sourcing The Q64TD is a mature product in the Mitsubishi Q-series range, sourced to order through our distribution channel.","metaTitle":"Mitsubishi Q64TD Thermocouple Input Module, 4-Ch, 0.1°C","metaDescription":"Precision thermocouple input module with per-channel accuracy specified per type: J-type 0.1°C resolution, cold junction compensation ±1.0°C, 20 ms/ch sampling.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"Mass":"0.25 kg","title":"Q64TD","Accuracy":"- Thermocouple type Measurement temperature range : Accuracy (° C) = (conversion accuracy) + (temperature characteristics) × (use ambient temperature change) + (cold junction compensation accuracy) conversion accuracy: Operating ambient temperature 25 ± 5 ° C Temperature characteristics: Operating ambient temperature change 1 ° C use Ambient temperature change: Operating ambient temperature out of the range of 25 ± 5 ° C","Depth (D)":"112 mm","Width (W)":"27.4 mm","Height (H)":"98 mm","Resolution":"B: 0.7 ° C.
