*** Ports are available to integrate APCs with smart devices or BMS systems. There are 0-10 Volt analog output
port for 4 level indication and remote start and stop ports available.
0-10 V output has been chosen to provide better voltage resolution. To interface with 0-5 volt input ICs or
microcontrollers a voltage divider circuit can be used. Maximum current is limited to 1 mA only.
