SPECIFICATION SHEET

DIN-A-MITE® B

The DIN-A-MITE® B power controller provides a low-cost,
highly compact and versatile solid state option for controlling
electric heat. This controller is designed and manufactured
with the quality features expected from Watlow®. DIN-rail
and panel mounting are standard on every control. There is
no need to worry about mercury, the DIN-A-MITE controller is
mercury free.

Features include single-phase and three-phase zero cross
switching up to 40 and 22 amperes, respectively, at 600VAC
(see rating curve). A unique, integrated design removes the
guesswork associated with selecting a proper heat sink and
adequate terminations for the application.

Variable time-base, 4-20mA process control and VAC/VDC
input contactor versions are available. A shorted output
alarm option is also available. All options are model number
dependent and factory configurable. This power controller
includes 200KA short circuit current rating (SCCR) tested up
to 480VAC to minimize damage in the event of a short circuit
when used with required fusing.

information

Control Mode, Zero Cross

• Control option C: VDC input, contactor output

• Control option K: VAC input, contactor output

• To increase service life on contactor models, the cycle time

should be less than three seconds

• Control option F: 4 to 20mA DC input, variable time-base

control output

Control Input

• AC contactor: 24VAC ±10%, 120VAC +10/-25%, 240VAC

+10/-25% @ 25mA max. per controlled leg

• DC contactor: 4.5 to 32VDC: max. current @ 4.5VDC is 6mA

per leg. Add 2mA per LED used to the total current

• Loop powered linear current 4 to 20mA DC: loop-powered,

control option F0 only (requires current source with 8.0VDC
available, no more than two DIN-A-MITE inputs can be
connected in series)

Alarm

Shorted SCR Alarm Option

• Alarm state when the input command signal off and a 10A or

more load current is detected by the current transformer (two
turns required for 5A and three turns for 2.5A)

Alarm Output

• Energizes on alarm, non-latching

• Triac 24 to 240VAC, external supply with a current rating of

300mA @ 77°F (25°C), 200mA @ 122°F (50°C), 100mA @
176°F (80°C) and a holding current of 200 µA with a latching
current of 5mA typical
