  • Description

The ABB 1SAP284100R0001 (DX581-S) is an S500-S safety digital input/output module combining 8 safety digital inputs (SIL2, or 4 at SIL3) with 8 safety digital outputs (SIL2/3) at 24 V DC, 0.5 A, wired 1-wire with 4 pulse outputs for line testing. Each input draws 7 mA and accepts 0-30 V with a 1-500 ms delay. Net weight is 0.13 kg.

Selection Notes

DX581-S combines safety inputs and outputs on one module, so it suits compact safety loops such as a guard-door interlock that both reads a switch and drives a contactor coil, instead of pairing two separate single-function modules. The 8 SDO transistor outputs are rated 0.5 A each, which covers small contactors and relay coils directly but not larger loads. Choose the DX581-S-XC variant instead when the cabinet needs the extended -30 to +70 C range.
