SIEMENS 6ES7277-0AA22-0XA0 New and Original High quality

6ES7277-0AA22-0XA0

The 6ES727-0AA22-0XA0 model product is the EM277 PROFIBUS-DP interface module of the Siemens S7-200 series PLC, designed specifically for industrial automation distributed control systems. It has the core function of connecting the S7-200 CPU to the PROFIBUS-DP network, supporting automatic baud rate negotiation from 9.6Kbps to 12Mbps, and achieving efficient data exchange with the main station system through RS-485 interface. The module size is 71 × 80 × 62mm, weighs only 175g, and is powered by a wide voltage of 20.4-28.8V DC, with a power consumption as low as 2.5W. Its 500VAC electrical isolation design can effectively resist electromagnetic interference in industrial sites, support 0-99 station address dialing settings, and support a maximum communication distance of 1200 meters (100 meters at 12Mbps). Module integrates 4 LEDs including DX MODE, DP ERROR, etc Indicator lights can display real-time communication status and fault information, widely used in manufacturing equipment monitoring, building HVAC control, water treatment pump valve regulation and other scenarios. By cooperating with PROFIBUS master stations, efficient data acquisition and remote control of small and medium-sized automation systems can be achieved.

Technical specifcations for 6ES7277-0AA22-0XA0

Communication interface and protocol:

Equipped with one RS-485 interface, supporting PROFIBUS-DP slave and MPI slave protocols, capable of communicating with PROFIBUS-DP master and other MPI devices.

Supports multiple baud rate automatic settings, including 9.6Kbps to 12Mbps, to meet different network transmission rate requirements.

Electrical parameters:

The power supply voltage range is from 20.4V DC to 28.8V DC, compatible with industrial standard power supplies.

The typical power consumption is 2.5W, with a maximum current consumption of 150mA from the backplane bus DC 5V and 180mA from the external 24VDC power supply.

Network capability:

The node address can be set within the range of 0-99 through a rotary switch, supporting a network size of 126 sites, of which up to 99 EM277 modules can be connected.

Each network segment supports up to 32 stations, which can be connected to the DP master station on the network through the PROFIBUS-DP port, while also serving as an MPI slave station to communicate with other master stations.

Physical characteristics:

The module size is 71mm (width) x 80mm (height) x 62mm (depth), with a weight of approximately 175g. It adopts a compact design for easy installation.

Equipped with 500VAC electrical isolation (external signals to PLC logic) to ensure system stability.

Cable and transmission distance:

The cable length supports 1200 meters (below 93.75Kbps), and the higher the transmission rate, the shorter the distance, for example, 100 meters at 12Mbps.

Indicator lights and status feedback:

The module integrates address switches and status indicator lights, which can intuitively display status information such as power, DP errors, CPU failures, etc.
