APPLICATION PROFILE
Applications
Supported use cases for AO523
|
|
Voltage actuation
|
Use all 16 channels for -10 to +10 V control signals to drives, positioners or analog actuators.
|
|
Current actuation
|
Configure up to eight designated channels for 0 to 20 mA or 4 to 20 mA current loops.
|
|
Mixed signaling
|
Combine current and voltage outputs within the supported channel-group architecture.
|
|
Dense control
|
Provide sixteen analog setpoints from one S500 module to reduce panel footprint.

SIGNAL AND CHANNEL BEHAVIOR
Measurement
Configuration and conversion characteristics for AO523
|
|
Channel groups
|
Outputs are organized in two groups; each group contains four U/I channels and four voltage-only channels.
|
|
Digital conversion
|
The module uses 12-bit conversion including sign for bipolar voltage operation.
|
|
Load limits
|
Voltage channels supply up to +/-10 mA; current loops support a total load of 0 to 500 ohm.
|
|
Settling
|
Typical settling time for a full-range change with resistive load is 5 ms.
|
|
MOUNTING AND WIRING
Installation
Installation requirements for AO523
|
|
Terminal unit
|
Install on ABB TU515 screw or TU516 spring terminal unit.
|
|
Supply
|
Provide 24 V DC process voltage and use the specified terminal-unit fuse arrangement.
|
|
Wiring
|
Use shielded cable and keep the current-loop burden, including conductor resistance, within 500 ohm.
|
|
Mounting envelope
|
Allow 67.5 mm width, 135 mm height and 84.5 mm maximum depth with unobstructed natural convection.
