Diagnostic alarm is parameterizable, and the module reports group errors via the SF red LED – useful for quick fault isolation on the line. Compact package (35 mm depth, 45 mm width, 130 mm height) fits standard ET 200SP backplane slots; total power loss is 0.7 W typical. ## Critical Ratings & Fit Input resistance is 10 MΩ for most thermocouple types, ensuring negligible loading on low-impedance sensors. Isolation tested at 707 V DC (type test) between channels and the backplane; common-mode voltage between inputs (UCM) can reach 20 Vpp AC. Integration time selectable from 2,5 ms to 100 ms; shielded cable max. 30 m. No hardware interrupt output – alarms are software-parameterized. Plan polling or diagnostics in your logic. This order code carries a current-production lifecycle – no last-time-buy clock. For a critical line, buy one for the cabinet; a spare on hand saves a shift when a channel fails on a high-temperature zone thermocouple.","metaTitle":"6ES7144-4PF00-0AB0 Siemens Analog Input 4xTC, 80mV","metaDescription":"Active 4-channel thermocouple/voltage input module for Siemens ET 200SP.
