Frequently asked questions

Common questions about AIROTRONICS from 3G Electric.

What are the available coil voltages for Airotronics encapsulated timing relays?

Airotronics encapsulated timing relays are available with coil voltages including 12V DC, 24V DC, 120V AC, and 230V AC. For example, the MC1003631H operates at 120V AC, while the MC4003601H operates at 24V DC. The TGKAD7102S3/102S3EE1HS is a 12V DC model. These options cover common industrial control voltages, allowing selection based on the available power supply in the control panel. When selecting a relay, confirm the coil voltage matches the control circuit voltage to ensure proper operation.

What operation modes are offered in Airotronics multi-function timing relays?

Airotronics multi-function encapsulated timing relays support several operation modes, including Delay On Make, Interval On, Single Shot, Resettable Single Shot/Watchdog, and Repeat Cycle On/Off Delay. For instance, the MC1003631H provides Delay On Make, the MC4003601H and MC7003601H provide Interval On, the MC4003631H provides Single Shot, the MC7003631H provides Resettable Single Shot/Watchdog, and the MC2003601H provides Repeat Cycle On/Off Delay. These modes allow engineers to implement various timing sequences with a single relay family. The specific mode is determined by the part number and is typically set at the factory or via external wiring, depending on the model.

What is the timing range of Airotronics encapsulated timing relays?

Select Airotronics multi-function encapsulated timing relays have an adjustable timing range from 1 second to 100 minutes. This range is available on models such as the MC4003601H and MC7003601H. Other models may have fixed or different timing ranges. The wide adjustment range allows the same relay to be used in applications requiring short delays (e.g., 1 second) up to long delays (e.g., 100 minutes). The timing range is typically set via an onboard potentiometer or external resistor, depending on the model. Always refer to the specific datasheet for the exact timing range and adjustment method.

What is the switching capacity of Airotronics surface-mounted relays?

Airotronics surface-mounted encapsulated timing relays are rated for switching capacities up to 10 A. For example, the MC2003601H, MC7003631H, MC4003601H, MC7003601H, MC4003631H, and MC1003631H are all rated at 10 A. This capacity is suitable for controlling small motors, solenoids, lamps, and other loads within the relay's rating. The actual load should not exceed the relay's contact rating, and the type of load (resistive, inductive, etc.) may affect the maximum switching capacity. Consult the datasheet for derating information and contact life expectancy.

Are Airotronics timing relays encapsulated, and what does that mean for installation?

Yes, Airotronics timing relays in the surface-mounted family are encapsulated. Encapsulation means the internal components are potted in a protective compound, which helps shield them from environmental contaminants such as dust, moisture, and vibration. This construction is beneficial in industrial environments where control panels may be exposed to such conditions. The relays are designed for surface mounting, allowing them to be attached directly to a panel or enclosure surface. This mounting style simplifies installation and saves space compared to DIN-rail or socket-mounted relays. Ensure the mounting surface is clean and flat for proper adhesion or fastening.

What part numbers are available for Airotronics single-function timing relays?

Airotronics single-function encapsulated timing relays include part numbers such as TGKAD7102S3/102S3EE1HS and THCU102S3E. The TGKAD7102S3/102S3EE1HS is a 12V DC relay with a single time-delay function, while the THCU102S3E is a single-function relay designed for surface mounting on panel doors. These models provide a fixed operation mode, which can be simpler to specify and install when only one timing function is needed. They are suitable for applications such as delay-on-make or interval timing where a dedicated function is required. For multi-function needs, consider the MC-series relays.
