Deterministic Network Communication and I/O Density Scaling
- EtherNet/IP Deterministic Networks: Translates dual-port industrial Ethernet protocols into backplane communications, maintaining real-time deterministic packet handling across ring and star network topologies.
- I/O Density Scaling: Accommodates up to 63 expansion I/O modules and 20 direct connections, enabling high-density distributed I/O architecture in harsh operational environments.
- Backplane Bus Capacity: Delivers 0.8 A backplane current output to drive local module logic, expandable using a 1738-EP24DC backplane extension power supply.
- Firmware Flash Compatibility: Supports field firmware update routines over the Ethernet network interface to preserve protocol timing and operational diagnostic integrity.
Frequently Asked Questions
Q: What is the maximum backplane output current provided by the 1738-AENTR module? A: The adapter provides a maximum backplane current output of 0.8 A, which can be supplemented using a 1738-EP24DC backplane extension power supply.
Q: How many modules and direct connections does the 1738-AENTR adapter support? A: The module supports up to 63 I/O modules, 5 rack-optimized connections, and 20 direct connections.
Q: What ingress protection rating is provided by the 1738-AENTR enclosure? A: The module enclosure meets IP65, IP66, IP67, and IP69K ratings when properly marked and installed.
Field Installation Guidelines
- Mount the adapter securely directly to the equipment surface using designated mounting holes, adhering to mechanical layout constraints.
- Connect dual-port Ethernet lines and power cables using rated industrial sealed connectors to ensure IP65/66/67/69K seal integrity.
- Verify that field power bus supplies do not exceed the maximum rating of 10 A at 10 to 28.8 VDC.
- Ensure external cable shield grounding is executed strictly in compliance with Industrial Ethernet installation practices to suppress noise interference.
