DESCRIPTION

· AS2702 (SAP4.1) is a next-gen AS-Interface slave device supporting up to 62 slave modules.
· Interfaces modules to an unshielded 2-wire AS-Interface bus for serial bidirectional data communication and power extraction.
· Operates in a master-slave fashion, with a central master unit sequentially addressing all connected AS2702 devices.
· Manages data communication with Manchester encoding and sin2-pulses (3V-8V Vpp) on a 30V DC bus.
· Regulates 30V DC down to 5V for internal circuitry and 24V for actuators/sensors (max 35mA).
· Each AS2702 can interface with up to 4 sensors or 3 actuators, enabling a system to connect 248 sensors and 186 actuators to a single master.
· Compatible with predecessor AS2701A (ISA3+), allowing integration into existing AS-Interface systems.

FEATURES

· Interfaces actuators and sensors to an AS-Interface bus.
· Offers two package options: SOIC 20 (full functionality) and SOIC 16 (no parameter port).
· Extracts DC power from the AS-Interface bus.
· Supports serial bidirectional data communication with a watchdog feature.
· Includes a 4-bit bidirectional data port with strobe for sensor polling and actuator control.
· Provides a 4-bit parameter port with strobe for sensor/actuator settings.
· Supplies 24V power to connected sensors and actuators.
· Features a periphery fault input to signal hardware failures.
· Integrates a 16 x 8-bit EEPROM for storing slave address and settings.
· Includes 2 LED outputs for visual operation status indication.
· Operates at -25°C to +85°C with a typical 30V DC bus voltage.
· Consumes ≤6mA (oscillator on, outputs idle) and supplies ≤35mA to sensors/actuators.

APPLICATIONS

· Industrial automation systems requiring standardized digital bus communication.
· Integration of sensors and actuators in AS-Interface bus systems.
· Systems needing flexible slave device options with power and data communication capabilities.
· Applications requiring compatibility with existing AS2701A-based AS-Interface systems.
