The 1SAP420500R0001 DC551-CS31-XC is a CS31 slave interface module with 8 fixed digital inputs and 16 configurable I/O channels that can be set as inputs or outputs, each rated 24V DC 0.5A. It sits on the CS31 fieldbus as a remote node, pulling 5 mA per input from the backplane supply. The transistor outputs drive standard 24V DC loads within the 0.5 A per-channel limit.
Rated for operation from -30 to +70 °C with a supply range of 20.4 to 28.8 V DC. The 0.1 to 32 ms delay time (τ) gives flexibility to debounce inputs in software or hardware.
