What is the difference between the AS-B875-001 and AS-B875-002 analog input modules?



The B875-002 module has either 4 or 8 individually isolated analog input channels. It has dip switches that allows you the option to setup for either 4-channel or 8-channel mode. The older B875-001 module was strictly an 8 channel analog input module. If you wanted 4-channels, you would use the B873-001 module.
