1SBP260105R1001 is a relay-type digital output module of ABB S500 I/O series, matched with Advant Controller 31 PLC system. New original spare stock and fully tested refurbished modules are supplied for industrial automation cabinet maintenance and system upgrading. The module uses standard DIN rail mounting and can be combined with other S500 digital and analog modules for mixed installation inside control cabinet.

1SBP is fixed part prefix for ABB S500 standard I/O spare part coding. 260105 stands for base hardware model of relay output module. Suffix R1001 represents factory standard hardware version and default configuration. Different trailing revision codes only modify partial internal components without changing module outline dimension, backplane pin definition and channel quantity.

It is configured with 8-channel mechanical relay isolated output channels, each contact supports AC250V or DC30V load driving. Single channel rated contact current is 5A under resistive load condition. Galvanic isolation exists between internal logic circuit and field contact loop with isolation withstand voltage up to 2500VAC. Operating ambient temperature ranges from -20℃ to +60℃, storage temperature -40℃~+85℃, working relative humidity 5%~95% under non-condensing environment. Protection grade is IP20 and conforms to IEC and UL industrial certification standards. Module working power is provided through S500 backplane bus from system power supply.

Rear gold-plated edge connector connects with S500 backplane, exchanging data with Advant main CPU via proprietary internal bus protocol. Front screw terminal block is reserved for field power and external load wiring. No independent external fieldbus interface is equipped; all control data transmission depends on cabinet internal backplane bus.

Receive switch control instructions from master PLC CPU, drive built-in mechanical relay contacts to open or close external load loops such as contactor coils, indicator lamps and small control solenoids. Upload relay abnormal status and loop overload information to main controller for system fault alarming. Unused output channels can be shielded via upper programming software to eliminate unnecessary fault prompts.

Commonly installed in control cabinets of papermaking production lines, metallurgical rolling equipment, chemical process automation and water treatment projects, used for on-site interlock output and auxiliary equipment startup-stop control of AC31/S500 PLC control system.

Cut off overall cabinet AC and DC power and wait minimum 10 minutes for residual charge discharge before module extraction or terminal rewiring. Complete semi-annual maintenance by cleaning dust on module surface and terminals with dry low-pressure compressed air and checking terminal screw fastening status. If external load cannot switch normally without field equipment failure, inspect external circuit open or short fault before module replacement. Prevent overvoltage surge from accessing output terminals to avoid internal relay and drive circuit damage.
