With CPU Units that are not equipped with a clock, if a battery is not installed, the internal capacitor will backup memory for 10 days at 25°C.

Note: Connect dummy resistance as required and maintain the load current between 10 and 150 mA when using
           01000 and 01001 for pulse outputs. The ON/OFF response time will increase if the load current is below 10 mA,
           preventing outputting high-speed pulses. The transistors will heat if the output current is greater than 150 mA,
           possibly destroying the elements.
