Control Mode, Zero Cross
• Input Control Signal Type C: VÎ (dc) input contactor. To increase
service life, the cycle time should be less than three seconds.
• Input Control Signal Type K: VÅ (ac) input contactor. To increase
service life, the cycle time should be less than three seconds.
• Input Control Signal Type F: 4 to 20mAÎ (dc) variable time base

Input Command Signal
• AC contactor
24VÅ ±10%, 120VÅ +10% / -25%, 240VÅ (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
4.5VÎ to 32VÎ (dc): maximum current @ 4.5VÎ (dc) is 6mA per leg.
Add 3mA if alarm option is included
• Loop powered linear current
4mAÎ to 20mAÎ (dc): loop-powered. Input Type F0 and F1 options
only. (Requires current source with 6.2VÎ (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 19.9mAÎ (dc), maximum voltage of 6.2V peak.
• ±5% input to output power accuracy, 0% to 100% of span (4.3 to
19.7mA or 12.3 to 19.7mA).
• Temperature stability is less than 0.15%/°C change.
Alarm
Shorted SCR Alarm Option
• Alarm state when the input command signal off and a 15A or more
load current is detected by the current transformer.
Alarm Output
• Energizes on alarm, non-latching
• Triac 24 to 240VÅ (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 200 µA with a latching current of 5mA typical
Current Sensing
• On-board current transformer (CT), typically 0.2VÅ (ac) output signal
per ampere sensed
