8142-DO-DC Emerson PAC8000 I/O Modules

The 8142-DO-DC in the Emerson PAC8000 series is a 16-channel digital output module, which is mainly used in industrial automation control systems to output the digital signals of the controller to external devices such as relays, contactors, indicator lights, etc. The following is a detailed introduction:

Output characteristics

Output points and types: 16-point source output.

Output speed: 3ms.

Output rating: voltage range is 12-42VDC, output current per point is 0.5ADC, and the maximum output current of the module is 6ADC.

Functional features

Discrete or pulse output: supports discrete output, which can control the on and off state of the device; also supports pulse output, which is used for devices that require pulse signal control.

Field terminal design: The field terminal is stuck on the backplane and accepts field wiring. No additional terminals or connectors are required. If it is damaged on site, it is easy to replace. And there is a mechanical key lock system to ensure the safety of the equipment.

Bus communication: PAC8000 I/O has an open architecture. By selecting the appropriate bus interface module (BIM) or controller, it can communicate with a variety of fieldbuses, such as PROFINET, PROFIBUS DP, Modbus, etc.

Application scenarios

Industrial automation production line: used to control motor start/stop, valve opening and closing, conveyor belt operation and other equipment.

Process control system: such as in the chemical, petroleum, power and other industries, control the start and stop of pumps, the switch of metering valves, etc.

Building automation system: control the switch of lighting systems, air conditioning systems, access control systems and other equipment.
