Module Requirements 6 3A1149D Module Requirements Each DGM requires a 9-30 VDC NEC Class 2 power supply. This is supplied to the DGM through pins 27, 51, 68, 69 on the D-Sub connection. Ground from this sup-ply should only be connected to pin 70 of the D-Sub connection. I/O Setup NOTE: Each DGM is s...

I/O Setup 3A1149D 7 DGM Digital Input Overview The digital inputs function only when power is supplied to pin 51 and there is a ground connection to pin 70. The dig-ital input is rated at 0-30 VDC, and requires an NEC Class 2 power supply connected to pin 51. The DGM provides optical isolation as sh...

I/O Setup 8 3A1149D 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...

I/O Setup 3A1149D 9 DGM Analog Inputs Overview The analog inputs function only when the DGM is connected to a power supply through the CAN connection; see Setup , page 14. Each analog input has a corresponding reference (ground) pin. • Type: Sinking • Voltage Rating: 0-10 Vdc • Input Impedance: 20 k...
