MS2110 Multi purpose TATTLETALE® with dry contacts that can be used to make two circuits and break another when tripped. Operates from 12 or 24 VDC or 24 VAC. The operating coil is intermittent duty and must be disconnected by an external circuit when tripped. The MS2110 is a replacement for 221PH, 169PH, 274 and 274PH.

two circuits and break another when tripped.
Operates from 120 VAC or Capacitor
Discharge Ignition. The operating coil is inter-	6	1	2	3	4	5

replacement for 100PH, 307CD, 307PHCD and 224CD.

MS2120 Multi purpose TATTLETALE® with dry contacts that can be used to make two circuits and break another when tripped. Operates from Magneto Ignition. The operating coil is intermittent duty and must be disconnected by an external circuit when tripped. The MS2120 is a replacement for 307, 307PH and 224.
