The Siemens SIMATIC ET 200SP HA AI 8xI HART HA (6DL1131-6BL00-0PH1) is a high-density HART-enabled analog input module for the ET 200SP High Availability distributed I/O system. It provides 8 channels of 4-20 mA current input with integrated HART communication and 16-bit resolution. The module features channel-by-channel 24V DC encoder supply (max 24 mA per channel), channel-wise isolation, and is certified for SIL 3 (EN IEC 62061) / PL e (ISO 13849-1) safety applications. With a relative error limit of approximately 0.1-0.2%, it delivers high-accuracy measurements for critical process variables. The module supports 1-wire connection via corresponding Base Units and is designed for redundant configurations with S7-410 automation systems. Ideal for safety-critical applications in oil & gas, chemical, and pharmaceutical industries.
FAQ
Q: What safety level does this module achieve?
A: The module is capable of SIL 3 per EN IEC 62061 and PL e per ISO 13849-1 when properly configured in a safety system.
Q: How many HART channels operate simultaneously?
A: 4 channels can operate with HART communication simultaneously; the remaining 4 channels operate without HART.
Q: What is the measurement accuracy?
A: The relative error limit is approximately 0.1-0.2% of the upper limit value, providing high-accuracy measurements.
Q: Is channel isolation provided?
A: Yes, each channel is individually isolated from others (channel-wise isolation).
Q: Can this module replace a standard ET 200SP analog input?
A: No. This is an HA (High Availability) module that requires specific HA Base Units and is designed for redundant systems. It cannot be used with standard ET 200SP Base Units.
Q: What encoder supply is available?
A: Channel-by-channel 24V DC encoder supply is provided, with a maximum source current of 24 mA per channel.
