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).
