Yokogawa I/O Modules A2MMM843
GENERAL This general specifications (GS) contains hardware specifications of I/O modules (for N-IO) that can be mounted on the base plates for N-IO I/O (A2BN3D, A2BN4D, or A2BN5D). Yokogawa I/O Modules A2MMM843
STANDARD SPECIFICATIONS Analog digital I/O module Analog digital I/O module (A2MMM843) has an analog I/O function and a digital I/O function for each channel. The analog input function, analog output function, digital input function, and digital output function can be switched by software setting for each channel. A dual-redundant configuration is available by mounting two units of the same modules. The function for each channel can be extended by mounting an I/O adaptor on the base plate for adaptor(A2BN3D).
