The DO module is a 16-channel 24VDC digital output module of the PAS300 system, which can be used with a universal base or a special relay base. The module unit consists of an I / 0 module, a module base, power bus and communication bus. The panel provides a rich state indicator light, used to display the module power supply, communication, channel working status, to enhance the efficiency of the work.

1. Active contacts require external auxiliary power supply and are selected by jumper. Does not directly drive the field equipment and needs to be configured with the relay module
2. Each channel can conduct fault output configuration separately, which can maintain the previous cycle data or output preset safety value in case of communication interruption or channel output failure.
3. Communication protocol based on Modbus, with online diagnosis, online replacement module, fast communication speed, and online maintenance and update program.
4. The field power supply and the system power supply are used to separate the power supply, and the field interference will not affect the digital circuit and communication.
