1SBP260104R1001 is an 8-channel analog output module from ABB S500 I/O family, designed to cooperate with Advant Controller 31 PLC system. Original new spare parts and fully inspected refurbished modules are available for industrial control cabinet maintenance and system modification. It follows standard DIN rail mounting dimension and can be assembled together with other digital and analog modules of S500 series in the same control cabinet.

1SBP serves as fixed prefix code for ABB S500 standard I/O spare parts. 260104 represents base hardware model of 8-channel analog output module. Suffix R1001 refers to factory standard hardware revision and default configuration. Modified suffix codes only update partial component layout while keeping module outline, backplane pin assignment and channel quantity unchanged.

The module is equipped with 8 isolated analog output channels, supporting standard 4–20mA current and 0–10VDC voltage output signals. Each channel adopts galvanic isolation between internal bus circuit and field output loop with dielectric withstand voltage up to 2500VAC. Internal conversion resolution is 12-bit. Operating ambient temperature ranges from -20℃ to +60℃, storage temperature from -40℃ to +85℃, working relative humidity 5%~95% under non-condensing environment. Protection class is IP20 and the product meets IEC and UL industrial certification criteria. Working power is obtained from system power via S500 backplane bus.

Gold-plated rear edge connector is inserted into S500 backplane to complete data exchange with Advant main CPU through dedicated internal bus protocol. Front screw terminal block is used for field control equipment wiring and external auxiliary power connection. No independent external fieldbus port is equipped; all command data is transmitted via cabinet built-in backplane bus.

Receive digital control commands sent from master PLC CPU, convert internal digital signals into standard continuous analog output signals to regulate field actuators such as regulating valves, frequency converters and adjustable drivers. Detect abnormal conditions like output short-circuit or overload and transmit fault information to main controller for system alarm. Unused channels can be disabled via upper programming software to avoid irrelevant fault prompts.

It is widely deployed inside control cabinets of papermaking production lines, metallurgical rolling equipment, chemical continuous process plants and water treatment automation systems, used for proportional adjustment of flow, pressure and temperature executing devices in AC31/S500 control system.

Disconnect all AC and DC power of the whole cabinet and wait at least 10 minutes for residual charge release before module removal or terminal rewiring. Conduct semi-annual maintenance by cleaning dust on module surface and terminals with dry low-pressure compressed air and checking screw tightness of each terminal. If field actuator fails to respond to control instruction without equipment breakdown, inspect external wiring fault before replacing the module. Prevent overvoltage from accessing output terminals to avoid burnout of internal output drive circuit.
