Communication is via a non-isolated serial link supporting Modbus master/slave on RJ45, RS-232, RS-485, or USB. The real-time clock is backed by a BR2032 lithium battery with a 4-year life at 25 °C. Compared to the TM241C24U, the TM241C40U adds 16 more I/O points (40 vs 24), including 10 additional standard inputs (16 vs 14) while keeping the same 4 fast inputs at 200 kHz. This makes the TM241C40U the right choice when the application needs more discrete sensing or control points without moving to a larger frame or adding an expansion module.","metaTitle":"Schneider
