● No galvanic isolation.
● Protection against: Short-circuit, overtemperature, and loss of ground.
● Automatic disconnection in case of undervoltage.

Input image
The image comprises 3 slots (n, m, d ≙ start address, see Addressing the I/O modules
(Page 75)):
● Slot 1: Digital inputs (DI)
– n+0 … n+8 (9 byte)
– X222.P3 - .P10 are rapid inputs
● Slot 2: 2 analog inputs (AI): m+0 … m+7 (8 byte)
● Slot 3: Diagnostics: d+0 .. d+1
