General Specifications
Operator Interface
• Command signal input and indication light
• Alarm output and indication light
• Input indicator LED
Amperage Rating
• See the output rating curve chart on page 3.
• Ratings are into a resistive heater load.
• Maximum surge current for 16.6 milliseconds, 380 A
peak
• Maximum I 2 t for fusing is 4000 A 2 s
• Latching current: 200mA minimum
• Holding current: 100mA minimum
• Off-state leakage 1mA at 25°C (77°F) maximum
• Power Dissipation: 1.2 watts per amp switched
• 200KA SCCR type 1 and 2 approved with the
recommended fusing (see page 3)
Line Voltage
• 24 to 48V~ (ac) units: 20.4V~ minimum to 53V~
maximum
• 120 to 240V~ (ac) units: 48V~ minimum to 265V~
maximum
• 277 to 600V~ (ac) units: 85V~ minimum to 660V~
maximum
Control Mode, Zero-Cross
• Input Control Signal Type C: V
Î (dc) input contactor.
To increase service life, the cycle time should be less
than 3 seconds.
• Input Control Signal Type K: V~ (ac) input contactor.
To increase service life, the cycle time should be less
than 3 seconds.
• Input Control Signal Type F: 4 to 20mA Î (dc)
proportional variable time base control.
Input Command Signal
• AC contactor
24V Å ±10%, 120V Å +10%/-25%, 240V Å (ac)
+10%/-25% @ 25mA maximum per controlled leg
• Do not use the DIN-A-MITE Vac-input models with a
temperature controller that includes an RC snubber
circuit across its output. Remove the RC snubber
circuit before placing the DIN-A-MITE into service.
• DC Contactor
4.5V Î to 32V Î (dc): maximum current @ 4.5V Î (dc)
is 6mA per leg, plus 2mA per LED used.
• Loop powered linear current
4mA Î to 20mA Î (dc): loop-powered. Input Type
F0 option only. (Requires current source
with 6.2V
Î (dc) available. No more than three
DIN-A-MITE inputs connected in series)
Linearity (Input Control Signal Type F)
• Full on point 19.5 to 19.9mA
Î (dc), maximum voltage
of 6.2V peak.
• ±5% input to output power accuracy, 0% to 100% of
span (4.3 to 19.7mA).
• Temperature stability is less than 0.15%/°C change.
Alarm (not available on multizone models)
Shorted SCR Alarm Option
• Alarm state when the input command signal off and a
10 A 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 240V~ (ac), external supply with a current
rating of 300mA @ 25°C (77°F), 200mA @ 50°C
(122°F), 100mA @ 80°C (176°F) and a holding
current of 200µA with a latching current of 5mA
typical.
