Allen-Bradley 1794-ASB Series FLEX I/O Module

Operating Voltage: Adopts 24V DC power supply. This voltage specification conforms to common standards in the industrial field, facilitating matching with industrial power supplies and other equipment and ensuring the stable operation of the module.

Current Consumption: During normal operation, the current consumption is usually around 150mA (under 24V DC condition). It has low power consumption, which can effectively reduce the overall energy consumption of the system and is suitable for long-term continuous operation.

Communication Protocol: Supports the EtherNet/IP protocol, which is an open network protocol widely used in the industrial field. It has the characteristics of high-speed data transmission, strong real-time performance and good compatibility, and can realize seamless communication with Rockwell Automation Logix controllers and other devices that meet the EtherNet/IP standard.

Communication Rate: Provides a 10/100Mbps adaptive Ethernet interface, which can automatically adjust the transmission rate according to the network environment. It can not only meet the needs of conventional data transmission, but also cope with a large amount of data interaction in high real-time control scenarios, ensuring efficient and stable data transmission.

Supported I/O Points: A single 1794-ASB module can support a large number of connected Flex I/O modules, depending on the module type and system configuration. It can usually meet the demand for I/O points in medium and large distributed control scenarios and can flexibly expand the system scale.

Dimension Specifications: The module has a compact design, with a width of about 32mm, a height of about 110mm and a depth of about 150mm. It occupies little space, is suitable for installation in control cabinets with limited space, and facilitates system layout.

Installation Method: Supports rail mounting, can be directly installed on standard DIN rails. The installation process is simple and fast, and the fixing is firm, which can adapt to the vibration environment of industrial sites.

Operating Temperature: Can operate stably in the temperature range of 0℃-60℃, able to adapt to temperature changes in common environments such as industrial production workshops and control cabinets, and can maintain reliable communication performance under high or low temperature conditions.

Relative Humidity: Can work normally in a relative humidity environment of 5%-95% (non-condensing), and can cope with humid industrial places such as food processing workshops and sewage treatment plants, effectively preventing circuit faults caused by humidity.

Anti-electromagnetic Interference: Complies with industrial electromagnetic compatibility standards (such as IEC 61000-6-2), has strong anti-electromagnetic interference ability, can resist electromagnetic interference generated by industrial on-site motors, frequency converters, high-voltage equipment, etc., and ensures the accuracy and stability of data transmission.

Vibration and Shock Resistance: The vibration resistance range is 10-500Hz, with an amplitude of 0.38mm or an acceleration of 10g; the shock resistance range can reach 15g (11ms). It can withstand vibration and shock generated during the operation of industrial equipment, ensuring the stability of the module structure and performance.

Efficient EtherNet/IP Communication: The 1794-ASB module builds a communication link based on the EtherNet/IP protocol, which can realize high-speed data exchange between the Flex I/O system and the upper-level control system. Both the real-time data collected by on-site I/O modules (such as temperature, pressure, liquid level, etc.) and the control instructions issued by the control system can be transmitted quickly and accurately through this module, meeting the real-time requirements of industrial control and ensuring precise regulation of the production process.

Flexible System Expansion: As the communication interface of the Flex I/O system, the 1794-ASB module supports connection with various Flex I/O modules (such as digital input/output modules, analog input/output modules, special function modules, etc.). Users can flexibly configure the number and type of I/O modules according to actual control needs, easily expand the I/O points and functions of the system, and adapt to changes brought about by production line expansion or process upgrading.

Powerful Diagnostics and Status Monitoring: The module has a complete self-diagnostic function, which can real-time monitor the operating status of itself and the connected Flex I/O modules, such as whether the communication is normal, whether the power supply is stable, and whether the module has faults. The working status of the module (such as power indicator, communication indicator, fault indicator, etc.) can be intuitively displayed through LED indicators. At the same time, it can upload diagnostic information to the upper-level control system, facilitating maintenance personnel to timely detect and troubleshoot faults, shortening system downtime and improving equipment availability.
