Description
AB 1797-PS2E2 rated power module
1797-PS2E2
The 1797 – PS2E2 serves as a linchpin in industrial automation setups where safety is non – negotiable. Industries such as oil and gas, petrochemicals, and mining often operate in environments where the presence of flammable gases, vapors, or combustible dusts is a constant threat. In these settings, the 1797 – PS2E2 plays a pivotal role in powering various sensors, actuators, and control devices. For example, in an oil refinery, it can provide power to the sensors that monitor the level of volatile liquids in storage tanks or the actuators that control the flow of flammable gases in pipelines. By doing so, it enables the seamless operation of the automation system while maintaining the highest standards of safety, thereby preventing potential explosions that could result from electrical malfunctions in a hazardous environment.

1797-PS2E2
The 1797 – PS2E2 is designed to meet the stringent requirements of intrinsically safe standards. This means that it is engineered to prevent the ignition of flammable substances in potentially explosive atmospheres. By isolating the input power circuit from the associated electrical control circuit in the hazardous area, it significantly reduces the risk of an explosion caused by electrical failures. Even in the event of a short – circuit or electrical arcing within the module, the energy released is restricted to a level that cannot ignite the surrounding explosive mixture. This intrinsic safety feature is not only a testament to its design excellence but also a critical factor in ensuring the safety of personnel and the integrity of industrial facilities in high – risk environments.
1797-PS2E2
With 8 output channels, the 1797 – PS2E2 offers remarkable flexibility. Each channel can be independently configured with Intrinsically Safe (IS) restrictions. This allows for the precise control and power supply to different devices and sensors within the automation system. For instance, in a chemical plant, one channel can power a temperature sensor in a volatile reaction chamber, while another channel can supply power to a solenoid valve controlling the flow of a reactive chemical. The ability to manage each channel independently ensures that the power distribution is optimized according to the specific needs of each device, enhancing the overall efficiency and safety of the system.
Housed in an IP 65/NEMA 7B – rated explosion – proof enclosure, the 1797 – PS2E2 is built to withstand the harshest of industrial conditions. The enclosure provides a high level of protection against dust, water ingress, and, most importantly, the containment of any potential explosions within the module. In addition, the improved input and output safety terminations, along with the specific cable compatibility features, further contribute to its safe operation in hazardous areas. The M20x1.5 input connector and M16x1.5 output cable glands are designed to securely connect cables of appropriate diameters, preventing any electrical leakage or sparking that could pose a risk in an explosive environment.
