Intended Purpose

The Analog Input/Output Module AX521 can be used as a remote expansion module at the following devices:

• S500 Bus Modules (e. g. DC505-FBP, CI592-CS31, CI501-PNIO, CI541-DP, CI581-CN)
• AC500 CPUs (PM5xx)

It contains the following features:

• 4 configurable analog inputs (I0 to I3) in 1 group (1.0…2.3)
• 4 configurable analog outputs (O0 to O3) in 1 group (3.0…4.3)

The configuration is performed by software. The modules are supplied with a process voltage of 24 V DC.

The inputs and outputs are electrically isolated from the other electronic circuitry of the module.

For usage in extreme ambient conditions (e.g. wider temperature and humidity range), a special XC version of the device is available.
