Product description
This product was updated. Alternative devices with small deviations are: MSR220K type T228111
Modification: Version with spring terminals RoHS/REACH compliant.
Further information can be found in our customer information: “New terminals for K-type devices”
The MS220K is a particularly econommical standard design in a 22.5 mm wide housing with vertically arranged terminals. Each terminal remains accessible even if all others are already occupied.
- 1 PTC resistor set 1...6 PTC resistors, or bimetal contacts
- Output relay with 1 change-over contact, 1 normally open
- Operating status display with LED
- Housing design K, vertical terminals order
- Width 22.5 mm
- Snap mounting on 35 mm standard DIN rail or screw mounting
Ein Ruhestrom überwacht den ohmschen Widerstand im Fühlerkreis. Im kalten Zustand liegt der Widerstand bei ≤ 250 Ω je Fühler (Fühlerkreis ≤ 1, 5 kΩ). Das Gerät ist eingeschaltet und die Klemmen 11,14 bzw. 21,24 geschlossen. Der Fühlerwiderstand ändert sich sprunghaft bei der Ansprechtemperatur NAT. Das Gerät schaltet ab bei einem Widerstand von 3...4 kΩ. Kontakt 11,12 schließt un d 11,14 bzw. 21,24 öffnet. Auslösegeräte Typ MS schalten selbsttätig wieder ein, wenn die Temperatur um ca. 5°C abgekühlt ist.
