Siemens 6EP3336-7SB00-3AX0

As a professional supplier, Yueyang Tongtu recommends this Siemens 6EP3336-7SB00-3AX0 multi-channel analog input module to you. This module is responsible for converting various analog signals received from the site, through high-quality isolation and conversion, into standard digital signals that can be recognized by the main controller of the system. We recommend this high-quality product that has undergone full-channel accuracy calibration and isolation withstand voltage tests. The purpose is to provide you with a replacement component with extremely high measurement accuracy, completely independent channels and no interference among them, so as to ensure the stability of the underlying measurement. If you need it, please come and purchase at any time.

Characteristics

The most distinctive feature of this Siemens 6EP3336-7SB00-3AX0 card is "extensive physical isolation between channels". Some cheaper input cards on the market only have simple optocoupler isolation, but this card with the specific suffix is truly a high-frequency transformer isolation. This isolation method not only prevents interference but also can firmly protect other channels from being affected when a severe short circuit or grounding fault occurs in the on-site cable of a certain channel. It will not spread the fault to the system backplane either.  When the system is running with power, as long as you pull out the handle according to the specifications, the system can smoothly remove this card without causing the entire node to crash or affecting other normal operating modules. This brings great convenience for on-site emergency troubleshooting.

Application scenario

This Siemens 6EP3336-7SB00-3AX0 is used in those places that require intensive collection of conventional analog signals. The most typical example is the temperature and pressure measurement circuits of the constant pressure and vacuum units in large oil refineries. The thermocouple signals from dozens of temperature measurement points are uniformly integrated into the DeltaV system. In the reaction vessel area of the chemical workshop, the 4-20mA signals from various level transmitters and pressure transmitters are all received and isolated by it. In addition, in the auxiliary control system of the hydropower plant or the wide area of the sewage treatment plant, it is used to access the field instruments that are very far away and susceptible to the interference of the ground potential difference. For all occasions that use the DeltaV system and require high reliability and high anti-interference analog input, it is the standard configuration.

Customer review

Many overseas customers express their approval in emails after using our products. A North American instrumentation engineer said he used to be afraid of this type of input card, which looked new, but the aging internal sampling circuit caused the reading to drift by a few percent. Troubleshooting such issues could drive him crazy. But the Siemens 6EP3336-7SB00-3AX0 purchased from Tongtu in Yueyang, from the meticulous packaging alone, can be seen to be sent by someone who is knowledgeable. After powering it on and using a calibration instrument to measure the full range, the error was so small that it could almost be ignored. The feel when screwing on the terminal block was extremely firm. This quality made these engineers who specialize in homosexual base measurement feel very reliable. From now on, they will definitely choose our key spare parts.
