High Memory Capacity: 1.5 MB allows for more extensive logic, tagging, and instruction sets compared to the L32E (0.75 MB).
Dual Connectivity: Built-in EtherNet/IP and RS-232 for modern and legacy system integration.
Modular I/O Support: Connect up to 30 1769 I/O modules directly to the CPU without a separate chassis.
Battery Backup: 1747-BA lithium battery preserves program and tag data during power outages.
Automated assembly lines
Packaging machinery
Water treatment and chemical processing systems
Complex PID control for temperature, pressure, or flow regulation
Q: How does the L35E compare to the L32E?
A: The L35E offers triple the memory (1.5 MB vs 0.75 MB), supporting more extensive programs and tags. Both have similar EtherNet/IP connectivity, but the L35E is better suited for larger, more complex control systems.
Q: Does it require a battery?
A: Yes, the 1747-BA lithium battery is required to retain memory during power loss.
Q: How many I/O modules can I connect?
A: Up to 30 local 1769 modules across 3 I/O banks, within the 4-slot distance rating from the power supply.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
