Limit switch GS225

• Limit switch for monitoring unit signals
• Two adjustable limit values ​​(floating)
• Switching function min. or max.
• Potentiometer with scale 0...100%
• Hysteresis and time delay is adjustable
• Inputs 0/0, 2...1 V, 0/2...10 V, 0/4...20 mA
• Supply voltage 18...30 Vdc unregulated
• Supply voltage 230 Vac/115 Vac or 24 Vac or 24 Vdc
• Plastic housing for mounting on a 35 mm standard mounting
  DIN-rail according to EN 50022 

Serves for controlling measuring values which are represented as electrical currents. A potential-free contact is switched when the corresponding presetted nomial value eith is fallen short (min.-function) or is exceded (max. function). Hysteresis and time delay are adjustable inside the unit by trimmers.
