General Description

AS2702 (SAP4.1) is a new generation AS-Interface slave device, which supports AS-Interface bus systems with up to 62 slave modules.

Key Features

• Interface device to connect actuators and sensors to an AS-Interface bus

• Flexible system solution offering 2 package options: SOIC 20 for full functionality; SOIC 16 for applications not requiring the parameter port

• DC power extraction from the AS-Interface bus

• Serial bidir. data communication with the bus

• Data communication watchdog

• 4-bit bidir. data port plus strobe to poll the sensors and control the actuators connected

• 4-bit parameter port plus strobe to provide settings to the sensors and actuators

• 24V power supply for the sensors and actuators

• Periphery fault input to signal hardware failure of the sensors and actuators

• Integrated 16 x 8 bit EEPROM to store (5 + 1)-bit slave address and settings

• 2 LED outputs to optically flag slave unit operation status

• Operating temperature Ta: - 25°C … + 85°C

• Operating supply voltage/bus DC voltage: typ. 30V

• Operating current (Osc. on, outputs idle): ≤ 6mA

• Supply for sensors/actuators: typ. 24V, ≤ 35mA
