AS2702-16

Specialized Overview

The AS2702-16 is an AS-Interface slave integrated circuit designed for industrial automation, supporting bus systems with up to 62 slave modules. It interfaces modules to the unshielded 2-wire AS-Interface bus for serial bidirectional data communication and power extraction. The device regulates a nominal 30V DC bus voltage internally down to 5V for internal circuitry and a nominal 24V supply for connected sensors and actuators. It features a 16 x 8 bit EEPROM for storing address and settings, a 4-bit bidirectional data port, and two LED outputs for status indication. The component operates within an ambient temperature range of -25°C to +85°C.

Specialized Feature Summary

• Interfaces sensors and actuators to an AS-Interface bus system via a 2-wire serial connection.
• Extracts DC power from the bus to provide regulated 5V and 24V supplies for internal logic and field devices.
• Includes a 16 x 8 bit serial EEPROM for non-volatile storage of slave addresses and configuration settings.
• Provides optical status indication through two dedicated LED output pins.

Specialized Applications

• Connecting actuators and sensors to AS-Interface bus networks
• Industrial automation control systems
• Slave module integration in standardized digital bus architectures

Specialized Procurement Notes

Verify the specific package variant required, as the SOIC 16 version lacks the parameter port available in the SOIC 20 option. Confirm that the application does not require the parameter port functionality before selecting this model. Check manufacturer documentation for current production status, as availability may vary. Ensure compatibility with existing AS-Interface master units and bus topology requirements.

Specialized Selection Notes

Select the AS2702-16 when the parameter port is unnecessary, as it omits the P0-P3 pins found in the SOIC 20 version. This package is suitable for applications requiring only the 4-bit data port for sensor and actuator control. Verify that the thermal resistance and power dissipation limits are compatible with the intended PCB layout and ambient operating conditions.

Specialized Part Context

The AS2702 is part of the SAP4.1 generation of AS-Interface slave devices. It maintains system compatibility with the predecessor AS2701A (ISA3+), allowing modules equipped with the AS2702 to operate in existing AS-Interface bus systems based on the older device. This backward compatibility ensures seamless integration into established industrial automation infrastructures without requiring immediate replacement of master controllers.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. For direct replacements, consult the manufacturer's official documentation or authorized distributors for updated product listings and cross-reference information.
