1SBP260106R1001, with alternative part code XE08B5, belongs to ABB S500 I/O product line matched with AC31/Advant Controller31 PLC control system. It is an 8-channel configurable universal analog input expansion module for field analog signal collection, adopting standard DIN rail installation mode to assemble with other digital and analog modules of S500 series in one control cabinet. Original new and fully tested refurbished products are available for industrial cabinet transformation and spare part replacement maintenance.

1SBP is fixed unified prefix coding for ABB S500 series standard I/O spare parts. 260106 stands for base hardware specification of 8-channel multi-type analog input module, alias XE08B5. The suffix R1001 represents factory default hardware revision and standard factory configuration; revised suffix codes only adjust partial internal component layout without changing channel quantity, backplane pin definition and outer dimension.

Equipped with 8 isolated universal analog input channels, compatible with multiple signal types including ±10VDC voltage, 0–20mA and 4–20mA loop current, Pt100, Pt1000, Ni1000 and Balco500 thermal resistance temperature signals. Internal AD conversion resolution reaches 12 bit, full-scale measurement accuracy keeps within ±0.1%FS. Galvanic isolation is arranged between internal bus circuit and field input circuit with isolation withstand voltage up to 2500VAC. External rated working power is 24VDC ±10%, typical power consumption is about 1.5W. Operating ambient temperature ranges from -20℃ to +60℃, storage temperature from -40℃ to +85℃, applicable humidity 5%~95% non-condensing. Protection grade is IP20 and the product complies with IEC and UL industrial certification standards.

Rear gold-plated edge connector inserts into S500 system backplane to realize high-speed data interaction with main CPU via proprietary internal backplane bus protocol. Front side is configured with screw type terminal block for field sensor wiring and external 24VDC auxiliary power access. No independent external fieldbus interface is reserved, all collected measurement data is uploaded to master controller through cabinet built-in backplane bus entirely.

Complete multi-type field analog signal acquisition, convert collected continuous analog signals into digital data recognizable by PLC main controller after internal filtering and AD conversion. Support flexible channel signal type configuration via upper programming software to switch between voltage, current and thermal resistance mode for different field transmitters and temperature sensors. Real-time detect input circuit open-circuit, short-circuit and over-range faults, upload fault codes and abnormal channel information to CPU for centralized system alarming. Unused channels can be disabled via program to avoid invalid fault alert.

Mainly installed inside control cabinets of chemical continuous production, metallurgy processing, papermaking automation, municipal water supply and sewage treatment, thermal power auxiliary control systems. It undertakes collection of temperature, pressure, flow and liquid level analog signals from on-site transmitters for closed-loop process regulation of AC31 control system.

Cut off total cabinet AC and DC power supply and stand by over 10 minutes for residual electricity release before module disassembly or terminal rewiring. Implement routine half-year maintenance, blow away dust on module surface and terminal wiring area with dry low-pressure compressed air and retighten loose terminal screws regularly. When measured data is abnormal without field sensor damage, check external wiring breakage or short-circuit failure before replacing the module. Strictly prevent overvoltage surge accessing input terminals to avoid breakdown of internal signal conditioning circuit.
