It mounts in the rack and handles control logic with built-in Ethernet 10/100 (10BASE-T/100BASE-TX) and serial Modbus interfaces (RS232/485). Designed for severe environments — conformal coating, IP20, gas/dust/salt resistant per IEC 60721-3-3. Draws 95 mA from the 24 V rack backplane. Supports up to four racks and 256 analog I/O points. Execution times: 0.12 µs Boolean, 1.16 µs floating point. Onboard diagnostics via seven status LEDs — activity, run, fault, memory card, I/O, Ethernet speed, and Modbus — so you can see line health without cracking a laptop. Carries CE, UL, CSA, RCM, EAC, UKCA, China RoHS, WEEE, IEC, and ATEX markings. Complies with IEC 61131-2, UL 61010-2-201, CSA C22.2 No 61010-2-201, IEC 61000-6-5, and IEC 61850-3.
