Features
- It is a digital clock of a 6-figure high-intensity LED (11mm of character quantities) display.
- It is the high precision quartz watch which used the crystal oscillation for the time base. (An external synchronization system is also possible)
- Low power consumption is measured by adoption of C-MOS-IC, it operates with a +5V (420mA) single power supply, and power failure guarantee operation by a battery can be performed easily. (Power supply unit with a power failure guarantee : PS-811)
- Since it is with a parallel BCD output (TTL positive logic), control of an external circuit is easy.
- With a latch memory.
- All of a time set and control are performed in a makeup point of contact or a TTL negative logic signal input.
- In a print card unit, all the input-and-output signals are based on the edge connector of 44pin.
