1SBP260196R1001 is a Profibus-DP communication adapter module of ABB S500 I/O series, designed for AC31 Advant Controller PLC system. It is DIN rail mounted and can be installed together with all kinds of S500 digital and analog modules inside control cabinet. Original production has been discontinued, genuine new spare parts and fully tested refurbished modules are available for legacy automation system maintenance and retrofit.

1SBP is fixed unified part prefix for ABB S500 I/O spare coding rule. 260196 stands for base hardware model of Profibus DP coupler module. Suffix R1001 means factory standard hardware revision and default configuration. Different suffix revisions only update partial component versions without changing overall dimension, backplane pin definition and bus specification.

The module draws operating power via S500 internal backplane bus from system power supply. It complies with standard Profibus-DP fieldbus specification and works as DP slave station on Profibus network. Galvanic isolation is implemented between internal rack bus and external Profibus bus circuit 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 the product meets IEC, UL and CE industrial certification standards.

Rear gold-plated edge connector plugs into S500 backplane to exchange data with all local rack I/O modules via proprietary internal bus protocol. Front screw terminal block is used for Profibus DP bus A/B line wiring and terminal matching resistor configuration. No additional spare communication expansion port is reserved under standard configuration; external host communication fully relies on Profibus-DP bus channel.

Carry out protocol conversion between S500 internal rack bus and external Profibus-DP fieldbus. Collect all input channel data of local S500 rack and upload data to upper Profibus master controller, meanwhile distribute control commands from master down to corresponding output modules inside the I/O rack. Continuously monitor external bus connection status and feed back bus break or short-circuit fault information to AC31 main CPU for system alarm.

It is widely installed in control cabinets of papermaking production lines, metallurgical rolling equipment, chemical continuous process control and municipal water treatment automation projects, used for connecting AC31 S500 I/O rack to upper DCS or PLC host through Profibus-DP fieldbus.

Disconnect full cabinet AC and DC power supply and wait at least 10 minutes for residual charge release before module removal or field bus wiring modification. Complete semi-annual maintenance by cleaning dust on module and terminal area with dry low-pressure compressed air and retighten all wiring fixing screws regularly. When Profibus communication fails without upper master breakdown, check external bus wiring and terminal resistor setting first before module replacement. Prevent overvoltage surge accessing bus terminals to avoid internal communication chip damage.
