4–20 mA current input
Self-powered by the current loop without an auxiliary power supply
1 Threshold adjustable via multi-turn potentiometer and open-loop detection
2 outputs, normally open contacts: 1 contact closed below the threshold, 1 contact closed above the threshold
both contacts open when the 4–20 mA loop is interrupted
Functional safety level: SIL2 / SIL3 according to IEC 61508
The DSL1-35mA-A is specifically designed for applications requiring a very high level of functional safety
; its analog design allows for complete control over failure modes,
and the absence of an auxiliary power supply significantly improves the product’s reliability.
