Product description

The new CPU 94x controller family is designed with a safe additional interface type SPUT 94x (Safe Processing Unit exTension) as a generically applicable SIL 4 CPU. 2 types of digital SIL 4 input/output modules are provided for signal conditioning. For central applications directly at the CPU, there is a backbone module for the CPU internal expansion bus (Q-bus), while for decentralized applications, safe inputs/outputs must be connected via a SIL 4 network with up to 100 m cable length. This concept offers maximum flexibility.
