FMBT-21 ABB Modbus TCP Adapter Module for Drives

FMBT-21 ABB Modbus/TCP Adapter Module

The FMBT-21 is a plug-in communication module for ABB drives. It puts a drive on a Modbus TCP network over Ethernet. Engineers use it for basic monitoring and control at low cost. The card draws power from the drive at +3.3 V, max 400 mA. It carries three bicolor LEDs for HOST, MODULE, and NETWORK/NET. Two RJ-45 ports allow daisy chaining. The PCB is conformal coated for harsh panels. Protection class is IP20.
