This memory headroom handles complex furnace thermal profiles — multiple ramp/soak segments and alarm thresholds — without segment truncation. Programming is via CX-Programmer through the RS-232C or USB port. ## Backplane integration and expandability Mounted on a CS1D backplane (not DIN rail), the CPU stays vibration-resistant and thermally coupled to the rack's cooling airflow. The 68-module limit means thermocouple input modules can sit physically near each furnace zone, reducing noise on millivolt signals. Communications include RS-232C and USB for programming and parameter backup. Approvals CE, cULus, Lloyd, and NK cover marine and safety-class installations.","metaTitle":"Omron CS1D-CPU65H CPU, 128K Words, 68 Modules","metaDescription":"Active production CPU for CS1D redundant system. 128K word memory, expandable to 68 modules/7 racks.
