Expert Review and Manager’s Insight
Expert Review: The E84DGFCAFNP suits plants that already run an AS-i bus. The IP65 housing handles tough floors and washdown zones. Five inputs and one output cover most small control tasks. The bus powers the unit, so field wiring stays simple. Plan cable runs within 100 m unless you add repeaters.
Manager’s Insight: This unit is current in the Lenze 8400 motec catalogue as of 2026-10. No replacement is named. That makes it a safe pick for new builds and spare stock. Buyers who run motec drives get a direct fit and a short install window. Keep one spare per plant to cut downtime.
Best-Fit Devices and Applications
- Lenze Inverter Drives 8400 motec drive units
- Decentralized conveyor and roller drive lines
- Packaging and handling cells with AS-i buses
- Washdown and outdoor zones that need IP65 parts
- Retrofit projects on existing AS-i networks
- Plants that want bus-powered field devices
FAQ
Q: Do I need to wire a separate power feed?
A: No. The AS-i 2-wire bus powers the unit at DC 24 V. Four inputs still work when mains is off.
Q: How many nodes can one bus carry?
A: Up to 31 standard or safe slaves. With A/B slaves, the bus can carry up to 62 nodes.
Q: What protection rating does the unit offer?
A: It meets IP65 per EN 60529. That suits dusty floors, hose spray and outdoor cabinets.
Q: Can I use star wiring?
A: Yes. The unit supports line, ring, tree, star and free topology. Star mains with repeaters reach up to 500 m.
Q: Experienced user tip: how do I cut install time?
A: Set the slave address before you mount the unit. Then plug in the M12 cable and power up once.
Q: Experienced user tip: how do I keep spare stock?
A: Hold one unit per drive group. The plug-in form lets a swap happen in minutes, so a spare protects uptime.
