Engineering Advantages
Quad-Channel Galvanic Isolation for Hazardous Areas
The 1797-PS2E2 provides four independent 9.5V DC outputs, each featuring robust galvanic isolation. This critical safety feature prevents dangerous energy from passing from the safe area to the hazardous area, protecting sensitive intrinsically safe sensors and transmitters. Engineers can power multiple field devices from a single module without worrying about ground loops or cross-channel interference.
Optimized Power for Intrinsically Safe Field Devices
Delivering 8.5W of power per channel, this supply is perfectly matched to the energy requirements of modern intrinsically safe instrumentation. The specialized 9.5V DC output ensures that field devices operate within their safe entity parameters, maintaining the integrity of the hazardous area classification while providing stable and consistent voltage.
Seamless FLEX Ex System Integration
Designed to mount directly onto the FLEX Ex bus, this power supply integrates effortlessly with other FLEX Ex I/O modules. Its compact, flame-proof enclosure design allows you to build dense, modular I/O racks for Zone 1 or Division 1 environments, significantly reducing panel space compared to traditional discrete safety barrier solutions.
FAQs
Q: What is the primary function of the 1797-PS2E2?
A: This module acts as a dedicated power supply for the Allen-Bradley FLEX Ex system. It takes a standard 12-32V DC input and provides four isolated 9.5V DC outputs specifically designed to safely power intrinsically safe devices in hazardous locations.
Q: How much power does each output channel provide?
A: Each of the four output channels delivers up to 8.5 watts of power. This capacity is sufficient to drive most standard intrinsically safe transmitters, sensors, and field instruments used in process automation.
Q: Why is galvanic isolation important in this power supply?
A: Galvanic isolation physically and electrically separates the input power from the output channels. In hazardous area applications, this prevents high-energy faults from reaching the field devices, ensuring the safety of the installation and preventing potential ignition sources.
Q: What input voltage range does this module accept?
A: The 1797-PS2E2 is designed for a nominal 24V DC input but operates reliably across a wide voltage range of 12 to 32V DC, accommodating various industrial control power supply configurations.

Tech & Buying Guide
Why 24V DC Power Supplies Standardize Modern Industrial Automation
Industrial control cabinets worldwide rely on 24V DC as the universal power standard for field instrumentation, sensors, and controllers. Walk into any manufacturing plant, and you will find PLCs, human-machine interfaces (HMIs), and smart actuators running on extra-low voltage DC. Standardizing on 24V DC enhances operational safety, lowers cabinet footprint, and maintains steady control performance across factory networks.
Essential Motion Control Commands: A Practical Guide for Engineers
Automation engineers often rely on precise position and speed control to drive modern factory machinery. Modern industrial systems, such as Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS), depend heavily on standardized motion instructions. Mastering these commands ensures operational safety, protects mechanical components, and optimizes cycle times across production lines.
Mastering Modern Industrial Joystick Controls in Heavy Automation
Industrial joysticks play a pivotal role in human-machine interaction across heavy material handling and mobile hydraulics. These tactile controllers translate complex operator movements into precise electrical signals for PLCs, motion controllers, and DCS networks. Consequently, selecting and installing the right joystick architecture ensures operator safety, reduces fatigue, and optimizes equipment performance.
