Product Specs
The DRF series DIN rail signal conditioners are designed to accept a broad range of input signals, such as ac and dc voltage and current, frequency, temperature (thermocouple and RTD), and process transducers, and provide standard process outputs of either 4 to 20 mA, or 0 to 10 Vdc. The DRF series feature a modern housing design, that is easily mounted on standard 35 mm DIN rails. Connections are safely and securely made through pluggable screw terminal connectors, with input and output connections on the opposite sides of the module.
The DRF-VDC and the DRF-VAC voltage signal conditioners accept dc and ac voltages respectively and provide an isolated 0 to 10 Vdc or 4 to 20 mA output. Models are available with three different power options, 24 Vdc, 120 Vac and 240 Vac.
The DRF-VDC and DRF-VAC are ideally suited for industrial applications. All models mount on a standard 35mm DIN rail and provide galvanic isolation between input, output and power up to 3500 Veff (model specific).

10% failure out of the box. LONG lead times.
My machine is a tester for AC motorized units. Originally bought 10 pieces for voltage isolation. Six week lead time. One unit bad out of box (replaced after 5 week wait). I needed 10 more to add current measurements. Again, one of ten bad out of box. That's 2 bad out of 21. Bought for price but not worth it.

Pretty reliable
We had eighteen of these installed on a system upgrade in 2010. We had one fail now in 2019, so I feel that these are pretty reliable.

According the the manual, the DRF sensors can be set, using DIP switches, to different input ranges. Can the DRF-VDC-24VDC-65V-0/10 bet set for a 650 Vdc input>
Yes, as long as you have a stable calibrated source you can change range and adjust per procedure in the manual.
