The schematic diagram of Figure 2-3 is that of a(n) a) discrete output module. c) discrete input module. b) analog output module. d) analog input module.

The purpose of the filter section is to a) aid in fault diagnosis. b) set the minimum level of voltage that can be detected. c) protect against electrical noise interference. d) separate the higher line voltage from the logic circuits.
