ABB AC522 AC500 Analog Input/Output Module
Eight configurable analog channels combine sensor acquisition and actuator control in one S500 module.
Overview
ABB AC522 is an AC500 S500 analog input/output module with eight software-configurable channels. Every channel can be used for voltage, current or resistance-temperature input functions, while all eight channels support voltage output and channels C0 to C3 additionally support current output. The module provides 12-bit resolution including sign, channel LEDs, module-level isolation from the I/O bus and direct parameterization through the AC500 engineering environment. Its mixed-channel architecture is intended for compact stations where the required analog input and output balance changes between applications.

Features
Core Functions
- Configures every channel independently for the supported signal mode.
- Uses all eight channels for voltage output and reserves current-output capability for C0 to C3.
- Supports resistance-temperature measurements alongside voltage and current input modes.
- Provides one signal-status LED per configurable channel.
- Protects I/O channels against reverse polarity, reverse supply, short circuit and temporary overvoltage up to 30 V DC.
- Exchanges process data through the S500 I/O bus.
Product Identity
- Manufacturer: ABB
- Model: AC522
- Product Type: AC500 S500 analog input/output module
- Status: Active product
Applications
- Compact AC500 stations that need a variable mixture of analog inputs and outputs.
- Process skids combining transmitter acquisition with proportional valve or drive-reference outputs.
- Machine modules using Pt100, Pt1000 or Ni1000 temperature signals with analog command outputs.
- Central or distributed S500 nodes where eight configurable channels reduce module count.
- Retrofit projects that must preserve the exact AC522 current-output channel boundary.
Lifecycle
- ABB lists article 1SAP250500R0001 in the Active lifecycle phase.
- The AC522-XC is a separate extreme-environment article and must not be substituted by changing only the label.
- Plan the channel map before replacement because current output is limited to C0 through C3.
- Retain the required terminal unit, 24 V process supply and existing I/O-bus configuration.
- After replacement, restore every channel mode and verify scaling, diagnostics and safe actuator response.
FAQ
Can all eight AC522 channels generate current outputs?
No. Current output is available only on channels C0 to C3; all eight channels can be configured for voltage output.
Which sensor ranges can AC522 measure?
ABB documents voltage, current, Pt100, Pt1000 and Ni1000 input modes.
What resolution does the module use?
The AC522 provides 12-bit resolution including sign.
How are channel states indicated?
One yellow LED is provided for each configurable analog channel.
What is the documented maximum analog cable length?
ABB specifies 100 m when the conductor cross-section is greater than 0.14 mm².
Is article 1SAP250500R0001 still active?
Yes. ABB lists the standard AC522 article in the Active lifecycle phase.
