The Siemens 6ES7288-5AQ01-0AA0 is a compact SIMATIC S7-200 SMART signal board providing one analog output for voltage or current operation. It supports -10 V to +10 V voltage output and 0 to 20 mA current output, making it suitable for compact control architectures where an analog command signal is required.
One configurable analog output is provided for voltage or current operation.
The output supports -10 V to +10 V or 0 to 20 mA depending on the selected signal type.
Voltage mode provides 11 bits plus sign; current mode provides 11-bit resolution.
Output diagnostics include wire-break and short-circuit detection with output-status indication.

A single analog output channel supports either voltage or current operation.
Resolution is specified as 11 bits plus the sign bit.
Current output uses an 11-bit resolution specification.
Within a SIMATIC S7-200 SMART control architecture, the SB AQ01 adds one analog output where a digital controller must provide a continuously variable command. The selectable voltage/current capability allows the output channel to match the required analog interface.
The exact part number is commonly relevant when an S7-200 SMART installation develops an analog-output problem, when the existing signal board requires replacement, or when a control cabinet must be restored with the same hardware configuration.
A failed analog output can prevent the connected process device from receiving its intended variable command. Depending on the controlled process, this may interrupt automatic regulation, trigger an abnormal operating condition, or contribute to production downtime.
The module provides wire-break diagnostics.
Short-circuit diagnostics are supported.
An LED provides output-status indication.
Fast handling for industrial automation replacement requirements.
Warranty support for your replacement purchase.
Supplied as a new industrial automation component.

It provides one analog output that can operate with either -10 V to +10 V voltage output or 0 to 20 mA current output.
The maximum resolution is 12 bit. In voltage operation it is specified as 11 bit plus a sign bit, while current operation is specified at 11 bit.
The signal board provides diagnostics including wire-break and short-circuit detection, together with an LED indication for output status.
The signal board measures approximately 35 mm in width, 52.2 mm in height and 16 mm in depth, with an approximate weight of 17.4 g.
The Siemens product information specifies that reparameterization in RUN is not supported.
