DGM Digital Outputs Overview

The digital outputs function only when power is supplied to pins 27, 68, and 69 and there is a ground connection to

pin 70. The digital output is rated at 0-30 VDC, and requires an NEC Class 2 power supply connected to pin 27 for

supply bank 1, pin 69 for supply bank 2, and pin 68 for supply bank 3. The DGM provides optical isolation as shown

in the following illustration.
