Description
The Electronic Component Model 701A22147 is an IC chip used in the AS-Interface system for signal transmission between the master and the slaves. It is connected to a parallel two-line wire, known as the AS-Interface line, via a polarity protection diode and a suppressor diode. The IC extracts its own power and power for peripherals from the line and detects the bus signals. It consists of various blocks including receive block, transmit block, digital logic block, emergency control block, internal and external power supply with signal decoupling, oscillator, power on reset, and high voltage I/O.
Specifications and features
- Simple two-wire bus (AS-Interface line)
- Transmission of both power and signal on the AS-Interface line
- Decoupling of power and signal by the IC without additional external devices
- Transmitting protocol for using the IC and the AS-Interface master in the transmit/receive modes
- Switching of max. 31 AS-Interface slave ICs on one bus possible
- Power supply of peripheral devices from the AS-Interface slave IC of up to [email protected]
- Only few external devices necessary for operation (quartz, 4 capacitors, E2PROM)
- Storing of the configuration data and the slave address in one E2PROM
- Quartz oscillator for 5.333 MHz without external capacitances
- Standards: AS-Interface–Spec V2.0 and EN 50295
Application Scenarios
The Electronic Component Model 701A22147 is commonly used in AS-Interface systems for various applications including industrial automation, process control, factory automation, and robotics. It is suitable for use in systems where simple two-wire bus communication is required, and power and signal transmission are combined on the same line.
Comparison
