I am currently in search of standard loop diagrams for the following setups: 1. Connecting a 2 wire pressure transmitter to an MTL isolator (preferably 055 range) and then to a PLC analogue card (preferably Siemens or Allen Bradley). 2. Connecting a 4 wire RTD to an MTL isolator (preferably 055 range) and then to a PLC analog card (preferably Siemens or Allen Bradley). 3. Connecting a 2 wire Solenoid valve to an MTL isolator (preferably 055 range) and then to a PLC analog card (preferably Siemens or Allen Bradley). I am also in need of recommendations for cable specifications suitable for connecting to a solenoid valve in a hazardous area. Can anyone provide assistance with this?
Have any information about this topic? Need more details on this? Let's talk about it!
If you are familiar with the pressure transmitter you need, understand MTL devices, and have the specifics on the RTD sensor and solenoid valve models, why not share some links for reference? This will help us further understand the products you are referring to.
For a similar example, check out the data sheet available at: https://www.instrumart.com/assets/MTL-4500-5500_Datasheet.pdf.
Considering the diagrams, you may want to look into technical manuals or contact the manufacturer's support team directly, they usually provide accurate materials for such setups. As for the cable specifications for solenoid valves in hazardous areas, EPR (Ethylene Propylene Rubber) insulated cables are often recommended because they offer excellent flame, heat, and moisture resistance. Nonetheless, cable selection could vary depending on the specific hazardous conditions or standards in your location. Always confirm with a local industry expert or electrician.
You might want to consider using shielded twisted pair cables for your 2-wire and 4-wire connections since these will help limit signal interference. Your choice ultimately depends on environmental factors like surrounding electrical noise, temperature, and humidity. For connecting in a hazardous area, you need to use 'Ex' rated cables which have been designed to handle such environments. As for those specific wiring diagrams, you might have some luck reaching out directly to MTL or Siemens/Allen Bradley technical support. They often have resources like that readily available to provide.
Hey there! For your setups, I recommend checking out the MTL documentation and their specific loop diagrams; they often provide great resources for the isolators. For the two-wire pressure transmitter and solenoid valve, make sure you’re using twisted pair cables to minimize noise, and for RTDs, look into shielded cables to help with interference. Regarding the hazardous areas, you'd want to look into using cables rated for the environment, like LSZH (Low Smoke Zero Halogen) or other similarly rated options to ensure safety. If you haven't already, the Siemens and Allen Bradley manuals can also offer detailed wiring diagrams that could be really helpful. Hope this helps!

Answer: 1. How do I connect a 2-wire pressure transmitter to a PLC with MTL isolators? - To connect a 2-wire pressure transmitter to a PLC with MTL isolators, you can refer to standard loop diagrams for guidance. Typically, you would connect the pressure transmitter to the MTL isolator and then to the PLC analog card.
Answer: - When connecting a 4-wire RTD to a PLC with MTL isolators, you would typically wire the RTD to the MTL isolator and then to the PLC analog card. Refer to standard loop diagrams for detailed instructions.
Answer: - To connect a 2-wire solenoid valve to a PLC using MTL isolators, follow standard loop diagrams. Connect the solenoid valve to the MTL isolator and then to the PLC analog card as per recommended practices.
Answer: - When selecting cable specifications for connecting a solenoid valve in a hazardous area, ensure you choose cables that meet the required safety standards for hazardous environments, such as being explosion-proof or intrinsically safe. Consult relevant guidelines and regulations for specific recommendations.
