DESCRIPTION

· AS2702 (SAP4.1) is a next-gen AS-Interface slave device supporting up to 62 modules.

· Interfaces with unshielded 2-wire AS-Interface bus for serial bidirectional data and power extraction.

· Operates in master-slave mode, cyclically addressed by a central master unit.

· Manages data communication with Manchester encoding and sin2-pulses (3V-8V Vpp) on a 30V DC bus.

· Regulates bus voltage to 5V for internal circuits and 24V for actuators/sensors (max 35mA).

· Connects up to 4 sensors or 3 actuators per slave, scaling to 248 sensors and 186 actuators per master.

· Compatible with AS2701A (ISA3+), ensuring backward integration.

FEATURES

· Interfaces actuators and sensors with AS-Interface bus.

· Available in SOIC 20 (full functionality) and SOIC 16 (no parameter port).

· Extracts DC power from the bus for operation.

· Supports serial bidirectional data communication with a watchdog feature.

· Includes 4-bit bidirectional data port and strobe for sensor/actuator control.

· Features 4-bit parameter port and strobe for sensor/actuator settings.

· Provides 24V power supply for connected devices.

· Peripheral fault input for hardware failure signaling.

· Integrated 16 x 8-bit EEPROM for slave address and settings storage.

· Two LED outputs for operational status indication.

· Operates at -25°C to +85°C with a typical 30V bus voltage.

· Consumes ≤6mA (oscillator on, outputs idle).

· Supplies 24V to sensors/actuators at ≤35mA.

APPLICATIONS

· Industrial automation systems utilizing AS-Interface bus technology.

· Integration of sensors and actuators in automated manufacturing environments.

· Systems requiring robust, standardized digital communication solutions.

· Applications needing backward compatibility with AS2701A (ISA3+) based systems.
