APPLICATION:
'DEEPL' Automatic Semaphore Indicators are used in mimic diagram
on Control and Instrumental Panel to indicate open or close
position of isolator, Earth switch, Circuit Breaker, PT On/Off
switch. The pointer takes up position of the supervised equipment
and turns right angle when breaker, isolator etc. is in open
position, it takes up intermediate position i.e. 45 °
on failure supply. Our indicators are enclosed in Glass cover
with Black dial which matches with all mimic colours and hence
there is no necessity to paint the mimic colour on the dial.
SPECIAL FEATURES:
- Type
Tested as per IS-3231 -
1965 at IDEMI Bombay.
- High Operating torque and positive
action.
- Coils are continuously rated for
24-30 V DC.
- Withstands 2.5 KV HV Test.
- Very Low Burden (Less than 15mA)
- Indicator is dust proof.
- Available in round bazel having 36mm, 48mm and 63mm dia
- We make two types high-burden and low-burden semaphores. High-burden semaphores are supplied for voltage upto
30V DC for direct operation and 1K 6W resistor for 50V DC, 3K 6W resistor for 110V DC and 9K 12W resistor for 220V DC.
Low-burden semaphores can be used for higher DC voltage of 110V DC using 6K Ohms, 6W resistor
and for 220V DC using 16-18K Ohms 12W Screw in type resistor,
in series on centre terminal.
- Fully type tested including for 1 lakh Mechanical operations.
