MS2100 Multi purpose TATTLETALE ®
with dry contacts that can be used to make
two circuits and break another when tripped.
Operates from 120 VAC or Capacitor
Discharge Ignition. The operating coil is inter-
mittent duty and must be disconnected by an
external circuit when tripped. The MS2100 is a
replacement for 100PH, 307CD, 307PHCD and 224CD.

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.

NOTES
The chart above indicates features/configurations available for each model.
1. Coil Voltage-Coils are specific voltage rated or multiple voltage rated.
2. Contacts-This is the control circuit output. In the latched position the NCH con-
tact has a “hot” output; in the tripped position the NOH contact has a “hot” out-
put. In the latched position, the NCG has a “grounded” output; in the tripped
position, the NOG has a “grounded” output.
3. Latch Type-Refers to whether the magnetic coil is momentarily energized to trip
or requires continuous power in the operating mode and de-energizes to trip.
4. Reset Type-Refers to manual or electric reset; manual indicating type is a TAT-
TLETALE ® .
5. Time Delay-Indicates operation of the time delay.
6. Coil Resistances in OHMS, or coil and resistor
