1SBP260103R1001 is an 8-channel analog input module belonging to ABB S500 I/O series, specially matched for Advant Controller 31 PLC control system. Original genuine stock and fully tested refurbished products are available for automation system maintenance and cabinet reconstruction. The module adopts standard DIN rail mounting structure and can be collocated with other S500 digital and analog modules for mixed installation inside control cabinet.

1SBP is fixed part prefix of ABB S500 standard I/O spare coding specification. 260103 stands for base hardware model of 8-channel analog input unit. Suffix R1001 indicates factory standard hardware revision and default signal type configuration. Different tail codes only adjust partial circuit revisions without changing overall dimension and backplane pin definition.

This module owns 8 isolated analog input channels, supporting standard industrial 4-20mA current signal and 0-10VDC voltage signal input. Built-in isolation circuit between field side and internal control bus with dielectric withstand voltage up to 2500VAC. Resolution reaches 12-bit for analog signal collection. Operating ambient temperature ranges from -20℃ to +60℃, storage temperature -40℃~+85℃, working relative humidity 5%~95% under non-condensing environment, protection grade IP20 and complies with IEC and UL industrial certification standards. Operating power is supplied via S500 backplane bus from system power supply.

Rear gold-plated edge connector is plugged into S500 cabinet backplane to realize data exchange with Advant main CPU through proprietary internal bus protocol. Front side is equipped with screw terminal block for field sensor power supply and analog signal wiring. No external independent fieldbus interface is arranged, all data interaction depends on cabinet internal backplane bus transmission.

Receive continuous analog signal from on-site pressure transmitters, temperature sensors and flow transducers, convert analog physical quantity into digital data and upload measurement values to master control CPU in real time. Support upper software parameter calibration and channel range setup; feed back channel open circuit or abnormal signal fault to PLC for system alarm when field loop fails. Idle channels can be masked via programming to eliminate useless fault alerts.

Mainly installed inside DCS auxiliary control cabinet of papermaking production line, metallurgical rolling process, chemical continuous production equipment and water treatment projects, used for collection of temperature, pressure and flow analog parameters in AC31/S500 automation control system.

Cut off total cabinet AC and DC power supply and wait minimum 10 minutes for residual electric charge discharge before module removal or terminal rewiring. Complete semi-annual maintenance to blow away surface and terminal dust with dry low-pressure compressed air and inspect tightness of terminal screws. In case of abnormal measured value without field sensor failure, check external wiring open or short circuit first before module replacement. Avoid overvoltage surge accessing input terminals to prevent internal signal acquisition circuit damage.
