The ABB 1SAP228100R0001 is a CI581-CN distributed I/O slice for CANopen networks, packing 4 analog inputs (voltage, current, RTD), 2 analog outputs, 8 digital inputs at 24 VDC, and 8 digital outputs sourcing 0.5 A per channel into a single IP20 housing.
I/O mix and fieldbus
Analog inputs accept voltage, current, and RTD signals; analog outputs handle voltage or current. Digital channels are all fixed-direction — 8 inputs and 8 outputs, no configurable combo channels. The CANopen slave interface uses transistor outputs; input delay is adjustable from 0.1 to 32 ms to match sensor filtering needs. No onboard Ethernet port — this is a pure CANopen node for legacy or real-time fieldbuses.
Power and wiring
Supply range is 20.4 to 28.8 V DC; the module draws 5 mA input current per channel when active. Output voltage follows the supply rail: 20.4 to 28.8 V DC. Each digital output is rated 0.5 A, transistor type with no per-channel isolation — watch the total package dissipation when driving high-side loads near the limit.
RoHS compliant per EU Directive 2011/65/EU and Amendment 2015/863. REACH declarable with SCIP number 9378345f-4dc7-415d-b557-0b3da711438f. WEEE category 5 (small equipment, B2B).
