SIPLUS S7-1200 CPU 1214C, order code 6AG1214-1HG31-2XB0, is the ruggedized version of Siemens' compact PLC for extended temperature ranges. Rated for -40 to 70 °C, it handles unheated cabinets or direct outdoor installation. Accepts 24 V DC supply from 20.4 V to 28.8 V, so it rides through line dips without browning out.
