A single 10BASE-T/100BASE-TX Ethernet port provides plant-network connectivity without an extra module. Four fast inputs (I0, I1, I6, I7) switch in 5 µs, supporting pulse/direction or single-phase A/B encoder counting for speed or position monitoring. The remaining inputs handle standard 35 µs turn-on and 100 µs turn-off — adequate for limit switches and pushbuttons. ## I/O and control loop detail The onboard adjustable PID regulator manages up to 14 simultaneous loops, useful for multi-zone temperature or pressure control without a separate loop controller. Analog input conversion takes 1 ms per channel plus one controller cycle — plan scan time accordingly for loop update rate. Mounts on TH35-15 or TH35-7.5 DIN rail per IEC 60715, or on a panel using the fixing kit. The 70 mm width matches standard contactor spacing; group it alongside motor starters without wasting rail space. Shock resistance 98 m/s² for 11 ms — suitable for machine-mount applications near pumps or conveyors.","metaTitle":"TM221ME16RG Modicon M221 Logic Controller, 16 I/O, Ethernet,","metaDescription":"Modicon M221 compact PLC with 16 discrete I/O, Ethernet port, 14 PID loops, real-time clock.
