Supply voltage, device and inputs
AB = 24 V AC (2, (4) inputs, also usable as 0 to 10 V analog inputs)
AC = 100, 120, 230, 240 V AC
DC = 24 V DC (2 (4) inputs, also usable as 0 to 10 V analog inputs)
DA = 12 V DC (2 (4) inputs, also usable as 0 to 10 V analog inputs)
Number of inputs/outputs (+ expansion)
12 = 8 I/4 O
18 = 12 I/6 O
19 = 12 I/6 O + expansion
20 = 12 I/8 O
21 = 12 I/8 O + expansion
