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.
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.
