MDrive® Plus

Archived: MDI3 NEMA 23 Modbus/TCP IP20

MDrive Plus NEMA size 23 (57 mm) Ethernet TCP/IP interface supporting both Modbus/TCP or MCode over Ethernet for simple TCP/IP networking.

This product offers a choice of eight 24 VDC multifunction programmable I/O points + two TTL high speed clock I/O points, or four 24 VDC I/O with TTL inputs for a remote encoder for following or reading off-shaft differential encoder

  • Holding torque range oz-in (N-cm): 90 …283 (64 … 200)
  • I/O connector options: Wire Crimp
  • Com connector: RJ45
