From Fortune 500 enterprises to innovative startups, leading companies choose Marvo for reliable automation and control components.
"Excellent service, especially from Mark, who stayed late to make sure the part arrived the same day since it was a critical component for me, even though it was my first time using Marvo. I will definitely use them again."
The Pepperl + Fuchs KCD2-RR2-EX1 is a high-performance temperature repeater designed for use in control and instrumentation technology. This device is engineered to provide galvanic isolation of signals, such as 20 mA and 10 V standard signals, ensuring reliable signal transmission in both hazardous and non-hazardous areas. It is particularly suited for transferring resistance values from RTDs or potentiometers, supporting 2-, 3-, or 4-wire techniques to meet varying accuracy requirements.
The KCD2-RR2-EX1 is an associated apparatus according to IEC/EN 60079-11, making it ideal for applications in Zone 2 hazardous areas. It is designed for stationary use and can be easily mounted on a 35 mm DIN rail, adhering to EN 60715 standards. The device features intrinsically safe circuits, allowing it to operate safely with intrinsically safe field devices in potentially explosive environments.
With a focus on functional safety, the KCD2-RR2-EX1 is compliant with IEC/EN 61508 standards, supporting up to SIL2 applications. It ensures a high level of safety by maintaining a safe state with a high impedance output or fault state, and a reaction time of less than 20 ms. This makes it a reliable choice for industries requiring stringent safety measures and precise signal isolation.

Big thanks to Rob for helping with an urgent request we had on a Friday afternoon. The part we needed was in Europe, and Rob went out of his way to get it ordered and delivered to us by the following Tuesday.City Bearings
Absolutely fantastic service. Rob was very helpful. Great communication. The requested part was shipped in no time.Konrad Eliaszuk
Found the component I was looking for at a great price. Excellent support from the staff as I was paying by wire transfer. Fast delivery and very good packaging.Adriano Tiberi
Extremely helpful. They shipped me a replacement unit the next day, and I was up and running within 24 hours. A brand-new replacement from the machinery manufacturer would have had a 7-day lead time.Sean Conlin
Found the part we needed at the best price. I spoke with Rob to make sure it was actually in stock, as many companies don’t really have it available to ship. It was ready, checked, and shipped, and we received it within a few days from their German stock. Would definitely use again and recommend.Chris Sentance
