Function & Feature 1. Isolate the DC input signal from the DC Output signal, which is directly proportional to the input signal. 2. These isolators can be used to prevent earth loops, which occur when a measuring source 3. Excellent temperature characteristic and good working stability. 4. It have an advantage over loop powered units, in that if for any reason the output lead should become disconnected, the input will not be saturated. 5. Fixed in a standard 35mm DIN rail or screwed on the cabinet. 6. Ultra-thin dimension, suitable for limited space, the control cabinet.
