Industrial Control Power Isolation Characteristics
The 1797-PS1N incorporates galvanically isolated output channels for intrinsically-safe Flex Ex applications. The module provides four isolated DC output channels at 9.5 V for connection to compatible Flex I/O 1797 Ex modules. The isolated architecture separates output circuits electrically to support hazardous-area instrumentation wiring requirements.
The Allen-Bradley Flex I/O 1797 platform uses modular I/O density scaling through distributed installation architecture. The power supply supports local power distribution for Ex I/O assemblies while maintaining electrical separation between field circuits and the supply input section.
The module is configured for installation inside an explosion-proof enclosure with conduit-based field wiring interfaces. Incoming AC or DC supply wiring and outgoing Ex power connections are routed through dedicated conduit entries.
Frequently Asked Questions
Q: Does the 1797-PS1N provide isolated output channels?
A: Yes. The module provides four galvanically isolated DC output channels for FLEX Ex system power distribution.
Q: Can the 1797-PS1N be installed as an open panel power supply?
A: No. The available documentation specifies installation inside an explosion-proof enclosure with conduit connections for field wiring.
Q: What input power sources are supported by the 1797-PS1N?
A: The module accepts 85-250 VAC input and supports 120-250 VDC input operation according to the listed specifications.
Field Installation Guidelines
Install the 1797-PS1N inside the specified explosion-proof enclosure before connecting field wiring. Maintain separation between incoming supply conductors and intrinsically-safe output wiring according to site electrical standards.
Use appropriate conduit routing for AC/DC input and Ex output circuits. Verify protective grounding, enclosure bonding, and cable shielding practices according to the installation requirements of the controlled hazardous-area system.
Confirm that connected FLEX Ex modules remain within the available output power capacity before energizing the system. Inspect terminal connections for correct polarity and secure mechanical retention during commissioning.
