MTL 8507-BI-DP MTL8000 Bus Interface Modules
MTL 8507-BI-DP is a Profibus DP bus interface module (BIM) under Eaton's MTL8000 series. It is specially designed for industrial automation scenarios, especially hazardous areas, and integrates functions such as signal isolation and stable communication. It is widely used in petrochemical, offshore and other harsh industrial environments. The following is a detailed introduction based on product technical information:
- Core Functional Positioning: It serves as a key communication and isolation component in industrial control systems. It undertakes the data exchange task between on - site devices (such as sensors, actuators) and the upper - level Profibus DP bus. It has electrical isolation and explosion - proof characteristics. While ensuring reliable signal transmission, it can resist dangerous voltages and currents, avoiding system failures caused by electrical interference and transient overvoltage, and is suitable for occasions with explosive gases or dust.
- Communication & I/O Related Parameters: The module takes Profibus DP as the core communication protocol and adopts RS - 485 as the LAN connector type. Its baud rate range is 9.6 kb - 12 mbaud, which can adapt to different communication speed requirements of industrial sites. In terms of data transmission, the maximum configuration of its data frame can reach 480 bytes, the maximum input and output data are 240 bytes and 480 bytes respectively, and the message response time is less than 4 ms, which can meet the real - time data interaction needs of industrial control. In addition, it is equipped with multiple digital input and output channels, which can receive switch status, sensor signals and other data, and can also output switch signals to drive relays and other external equipment.
- Electrical Performance: It adopts 24 VDC power supply, which is consistent with the common power supply standard of industrial automation systems and is easy to integrate into existing systems. It supports 4 - 20 mA and 0 - 20 mA input and output signal ranges, and the signal transmission accuracy can reach ± 0.1% of the full scale. The isolation voltage can reach 1000 V (some sources mark it as 1000 VDC), and the galvanic isolation technology is adopted to effectively reduce electrical noise interference and ensure the integrity of signal transmission.
- Physical & Environmental Parameters: There are slight differences in size data from different channels. One version is 22.5 mm in width, 90 mm in height and 120 mm in depth, and another version is 140 mm × 100 mm × 50 mm (length × width × height). Its weight is about 0.5 kg, and it supports DIN rail installation, which is convenient and fast for on - site assembly. It has excellent environmental adaptability, and its working temperature range is - 40 ° C to + 85 ° C. The 316 stainless steel shell gives it good corrosion resistance. However, there are differences in the protection level marked by different channels, with IP20 and IP65 mentioned, which can adapt to dustproof, waterproof and other different harsh environmental needs.
- Configuration & Operation: Users can configure the module through matching configuration tools. It supports parameter setting and logic customization of input and output channels to meet specific control requirements. Meanwhile, it can be configured with the help of GSD files. In the process of use, relevant status indicators can help users monitor the working state of the module in real time, which is convenient for troubleshooting and daily maintenance.
