It carries 22 total I/O — 6 digital inputs (24 V AC/DC), 5 relay outputs (3 A SPST shared common plus two independent commons), 7 analog inputs configurable for NTC, Pt1000, voltage, or current, and 4 analog outputs (0-10 V, 4-20 mA, or PWM). The unit is active current production, so that's another SKU you can spec into a BOM without worrying about end-of-life right now. Panel-mount with optional DIN-rail kit. Box dimensions are 3.3 x 3.2 x 1.4 inches (82.7 x 80.5 x 34.5 mm), so it fits a standard 4x4 junction box or a small panel cutout. IP65 rated per EN/IEC 60730, meaning it handles washdown environments without a separate enclosure. Powered by 24 V AC/DC ±10 %, draws 10 W. Ambient storage range -22 to 158 °F. For MRO benches: the 22 I/O count includes onboard USB-C, dual RS485, a display port, and a communication module port (TTL connector). That's a lot of connectivity in a shoebox-sized brick — consolidates separate I/O bricks and a controller into one bin location. ## Compliance & Lifecycle Current production, no end-of-life notice. Compliant with UL, CSA, and EN safety standards and EMC/LVD directives, pollution degree 2, overvoltage category II, with a built-in real-time clock (drift ≤30 s/month). Stocked item in Schneider catalog with standard lead times; no direct drop-in — form factor and I/O mix unique to the M173 platform. If cross-referencing a failed controller, check I/O count and analog config; this model adds analog output and wider temperature-sensing range.","metaTitle":"TM173OFM22R Modicon M173 Controller, 22 I/O, IP65","metaDescription":"TM173OFM22R is a current-production Modicon M173 programmable controller from Schneider Electric.
