connected Special I\/O Units, CPU Bus Units, and local digital I\/O modules. Featuring a dedicated logic execution hardware core, the processor maintains execution speeds down to 0.016 us min. for basic instructions and 0.048 us min. for special instructions across an expanded 400K-step program capacity.\u003c\/p\u003e\n\u003cp\u003eSystem instruction determinism is preserved via a fixed 100 us overhead processing period. Power draw is regulated to 0.42 A on the internal 5 VDC bus line supplied directly from the CPU rack power supply. Extended force-setting\/resetting capabilities across EM Area Banks 0 to 18 hex allow extensive real-time testing of expanded data registers without interruption to backplane bus velocity.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents \u0026amp; Ordering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Omron CJ2H-CPU68 Central Processing Unit\u003c\/li\u003e\n\u003cli\u003e1x CJ1W-BAT01 Backup Lithium Battery\u003c\/li\u003e\n\u003cli\u003e1x Serial Port Protective Cap\u003c\/li\u003e\n\u003cli\u003e1x Hardware Installation Sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Mounting:\u003c\/strong\u003e Secure the processor onto a standard 35 mm DIN rail or directly to a panel backplate using M4 hardware inside an IP54 enclosure.
