Frequently asked questions
Common questions about AIROTRONICS from 3G Electric.
What are the available operating modes for AIROTRONICS multi-function timing relays?
AIROTRONICS multi-function encapsulated timing relays offer several selectable operating modes depending on the model. Common modes include repeat cycle on/off delay, resettable single shot/watchdog, delay on make, one shot on break, interval on, and single shot. The specific modes available for a given part number are indicated in the product specifications. For example, the MC2003601H supports repeat cycle on/off delay, while the MC1003631H provides delay on make. Always verify the mode against your application requirements before ordering.
What voltage and current ratings are typical for AIROTRONICS surface-mounted timing relays?
AIROTRONICS surface-mounted timing relays are available in standard control voltages of 24V DC, 120V AC, and 230V AC. Current ratings are typically 10 A or 25 A, depending on the model. For instance, the MC4003601H is rated at 24V DC and 10 A, while the MC1004531J is rated at 120V AC and 25 A. These ratings are specified for resistive loads; derating may be required for inductive or capacitive loads. Consult the datasheet for exact specifications.
How are AIROTRONICS current sensor relays configured and installed?
AIROTRONICS current sensor relays, such as the HCSDC030A, are surface-mounted devices with quick-connect tab terminations for electrical connections. They feature an adjustable trip point ranging from 6 to 30 A, set via a potentiometer or DIP switch (depending on model). The relay operates on a 3 to 50V DC supply and provides a switched output when the sensed current exceeds or falls below the set point. Installation involves mounting the relay on a panel or DIN rail and wiring the load current through the sensing aperture or terminals. No status indicator is included on this model, so external indication may be needed.
What is the timing range for AIROTRONICS encapsulated timing relays?
AIROTRONICS encapsulated timing relays offer adjustable timing ranges that vary by model. For example, the MC4003601H (24V DC, 10 A) provides a timing range of 1 second to 100 minutes. Other models may have different ranges, such as 0.1 seconds to 10 minutes or 1 second to 30 minutes. The specific range is listed in the product specifications for each SKU. Timing is typically set via a potentiometer or DIP switch on the relay housing.
Are AIROTRONICS relays suitable for outdoor or washdown environments?
AIROTRONICS encapsulated relays are designed for surface mounting in indoor industrial environments. The encapsulation provides protection against dust, moisture, and vibration, but the relays are not rated for direct outdoor exposure or high-pressure washdown. For outdoor or wet locations, the relay should be installed inside a weatherproof enclosure with an appropriate IP rating. The relays themselves do not carry an IP rating in the available specifications; consult the manufacturer for detailed environmental ratings.
