The AO module is an 8-channel analog output module of the PAS300 system with an output range of 4-20 mA. The block unit consists of an I / O module, a module base, power bus and communication bus. The module panel provides a rich state indicator light to display the module power situation and field equipment communication, the working state of the channel to enhance the efficiency of work.

1. With the powerful over-flow pressure protection function, misconnecting 30VDC and short circuit will not be damaged.
2 With the perfect fault hardware diagnosis function, the panel design has a rich LED indicator light,
3. Fast communication speed; support hot plug; support online maintenance and update program
4. Communication protocol based on Modbus, with the function of online diagnosis and online module replacement.
5. The field power supply and system power supply isolation power supply design field interference will not affect the work of the module.
