No.7895-5/6

(2) Solenoid (constant voltage drive), stepping motor (constant voltage drive)

The shutter mode is ON at *LLLH input. The solenoid is driven by constant voltage at LHLH.

The constant voltage output is 4 times the VC2 pin input voltage.

The voltage is controlled by 2/3 in HOLD mode.

OUT1, 2, 3, and 4 outputs are set by VC1 input, and it becomes 4 times the constant voltage output.
