ABB AX522 S500 Analog Input/Output Module – 1SAP250000R0001

The ABB AX522, product number 1SAP250000R0001, is a versatile analog input/output expansion module for the ABB AC500 / S500 PLC platform. It combines 8 configurable analog inputs and 8 configurable analog outputs in a single industrial I/O module.

The AX522 is designed for industrial automation, process control, machine control and distributed I/O applications requiring multiple analog measurement and control channels.

8 Configurable Analog Inputs

The AX522 provides 8 individually configurable analog input channels. Depending on the configuration, the inputs can be used for common industrial voltage, current and temperature measurement signals.

• 0 to 10 V
• -10 to +10 V
• 0 to 20 mA
• 4 to 20 mA
• Pt100 temperature sensor input

The analog inputs provide 12-bit resolution including sign.

8 Configurable Analog Outputs

The AX522 also provides 8 analog output channels. All eight channels can be configured for voltage output, while channels 0 to 3 additionally support current output.

• -10 to +10 V – supported on all 8 outputs
• 0 to 20 mA – supported on output channels 0 to 3
• 4 to 20 mA – supported on output channels 0 to 3

The analog outputs also provide 12-bit resolution including sign.

Ideal for Process Control

With 8 analog inputs and 8 analog outputs in a single module, the AX522 is suitable for automation systems that need to simultaneously monitor multiple process signals and control analog field equipment.

Typical connected equipment can include pressure transmitters, flow transmitters, temperature sensors, level transmitters, variable frequency drives, control valves and industrial actuators.

Module-Wise Galvanic Isolation

The AX522 provides module-wise galvanic isolation between its channels and the internal I/O bus, supporting reliable operation in industrial automation environments.

24V DC Process Supply

The AX522 uses a 24V DC process supply. The module front labeling identifies the process supply as UP 24VDC 5W.
