Product Description: AO352 (7AO352.70) Analog Output Module

1. General Description

2. Key Features

• Dual Independent Output Channels: 2 electrically isolated output channels for simultaneous, independent control.

• Dual-Mode Signal Output: Selectable output per channel: ±10 VDC (voltage mode) or 0–20 mA (current mode).

• High Precision: 12-bit resolution for accurate, fine-grained analog signal control.

• Industrial Robustness: IP67 protection rating, resistant to dust, moisture, and electromagnetic interference.

• Integrated Safety: Built-in short-circuit protection and overload protection for each channel, preventing damage to connected devices.

• Modular Design: Screw-in module format, compatible with B&R X20 system backplane; easy installation and replacement.

• Wide Temperature Range: Operates reliably in extreme temperatures from -25°C to +70°C.

• System Compatibility: Seamless integration with B&R controllers via EtherCAT and other standard fieldbuses.

• Certifications: CE, UKCA, cULus (Class I, Division 2 hazardous locations), EAC approved.
