Yokogawa ALR121-S51 Serial Communication Module In Stock Brand New

Overview
The Yokogawa ALR121-S51 is a serial communication module that is used to connect a field control station (FCS) to subsystems such as FA-M3. It supports Modbus communication and can be used to exchange data between the FCS and the subsystem. The ALR121-S51 uses an RS-422/RS-485 interface and can be connected in a point-to-point or multipoint configuration. It is half-duplex and supports transmission speeds of 1200/2400/4800/9600/19200/38400 bps.
