Output Multiplexer Module AMM52T Yokogawa
The specifications of I/O Modules and I/O Module Nests (for RIO) for CENTUM CS 3000 and CENTUM CS 1000 systems.
2-Wire Transmitter Input/Output Multiplexer Modules
AMM42T receives up to sixteen 4-20 mA DC signals from a 2-wire transmitter. AMM52T outputs up to sixteen 4-20 mA DC
signals to a 2-wire transmitter. Output Multiplexer Module AMM52T Yokogawa
Input/output signals are not isolated between system and filed, and between channels.
