1) Coil data
(1) AC coils (50/60Hz)
(2) DC coils
Notes: 1. The allowable coil resistance range is ±10% when within 1,000Ω and ±15% when. 1,000Ω or higher.
2. The maximum applied voltage is the maximum voltage fluctuation value for the coil power supply. This value is not a permissible value for continuous operation.
(This value differs depending on the ambient temperature. Please contact us for details.)
2) Specifications
Notes: *1. This value can change due to the switching frequency, environmental conditions and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. Other specifications are same as standard type HC relay. Please see the standard type HC relay.
*3. Please maintain (reset) the relay more than once a year. Leaving it in the set position for long periods of time will cause the magnet to attenuate over the years.
This will decrease the holding power and cause failure of the set position.
4. With diode type (For DC)
1) Coil data
Same coil data as HC relay standard type for DC. Please refer to standard type information.
Please connect DC coil type built-in diode correctly by verifying the coil polarity.
2) Specifications
Notes: Other specifications are same as standard type HC relay. Please see the standard type HC relay.
* The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
5. With CR circuit type
1) Coil data
Same coil data as HC relay standard type for AC. Please refer to standard type information.
2) Specifications
Notes: Other specifications are same as standard type HC relay. Please see the standard type HC relay.
* The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
