For Underwriters Laboratories (UL) compliance, the unit must be installed within a suitable fire enclosure.

Read the following sections carefully to be sure that you are complying with all the safety requirements.

Select a NEMA rated enclosure and place the unit to allow easy access to the system ports (see other sections in this chapter and Appendix A).

To assure a NEMA 4 seal choose an approved enclosure that has a 14-gauge(0.075 in/1.9 mm thick steel or 0.125 in/3.2 mm thick aluminum) front face.

Be sure to account for the unit’s depth when choosing the depth of the enclosure.

Create a mounting location in the enclosure (see System Mounting Dimensions).

Be sure to place the unit at a comfortable working level

Working principle

In the industrial production process, sensors and other equipment transmit the collected analog and digital signals to the Xycom 81625DA control board through corresponding input channels.

The processor analyzes and calculates data based on pre written control programs and algorithms to determine whether the current production status is normal and whether control adjustments are needed for the equipment. If control is required, the processor converts control instructions into corresponding electrical or digital signals through output channels, transmits them to the actuator, drives the actuator to act, and achieves control of industrial equipment.

At the same time, the control board interacts with other devices or the upper computer through communication interfaces for data exchange. On the one hand, the collected data and equipment operation status information are uploaded to the monitoring center or upper computer for real-time monitoring and data analysis by operators; On the other hand, it receives instructions and parameter settings from the upper computer or other devices, adjusts the working state and control strategy according to the instructions, and ensures the coordinated operation of the entire industrial automation system
