TM5SAI6TH — 6-Channel Thermocouple Input Module for Modicon TM5
Six galvanically isolated thermocouple channels in a 12.5 mm housing — the TM5SAI6TH accepts J, N, K, and S types with 16-bit resolution and 0.1 °C measurement granularity. Powered from the TM5 backplane (24 VDC, 38 mA typical), it includes configurable input filtering from 1 to 66.7 ms to dampen electrical noise in industrial environments. Rated for 0–55 °C horizontal mounting with no derating, and CE, UL 508, and CSA C22.2 No 142 approvals cover machine-building compliance.
Integration Notes
The module occupies one slot on the TM5 DIN-rail backplane. Its 12.5 mm width makes it a good fit for high-density I/O banks where panel space is tight. Shielded cable is recommended for thermocouple wiring; the module's common-mode rejection exceeds 70 dB. Isolation between channels and bus is 500 Vrms, so external field-side faults stay off the backplane.
