PV- 1800: Power supply module with GSM MODEM

Digital outputs (CN2)

The PV1800 has 7 isolated digital outputs connected to a 10pin box header (CN2). The outputs are configured as PNP outputs with their transistors connected to an external supply voltage (+V_EXT). The table shows the connector layout:

Attention!

The user has to add proper free-wheeling diodes across inductive loads to protect the output transistors against high voltages.

The software interface is explained in section PV-1800 register interface.
