Connectors

The digital I/O section is found on all models except PV-1830 and PV-1730 versions. The digital inputs are bipolar isolated with a max. input voltage of +/- 30V.

There are 7 isolated digital P-channel outputs each capable of driving up to 0.5A. The load current must be supplied from an external voltage source not exceeding 30V.

The UPS connector contains control signals that can be used with external UPS circuitry.

The PV-1800 is equipped with several I/O connectors:

•One 2 pole pin header (KL1) for mains power in.

•One MMCX connector for GSM antenna.

•One 10-way box header (CN3) with non-isolated simple I/Os.

•One SIM Card connector (CN9) placed one the rear side of the PCB.

•One 10-way box header (CN1) for digital inputs.

•One 10-way box header (CN2) for digital outputs.

•One 10-way box header (CN5) for analogue inputs.

•One 10-way box header (CN6) for RS232.

•One PC/104 connector (CN8) for bus interface.

Furthermore, there are 10 connection pads/holes (CN7) for special UPS functions.
