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. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to “6. Usage, Storage and Transport Conditions“ in AMBIENT ENVIRONMENT section in Relay Technical Information. - *3. When using relays in a high ambient temperature, consider the pick-up voltage rise due to the high temperature (a rise of approx. 0.4% V for each 1C 33.8F with 20C 68F as a reference) and use a coil impressed voltage that is within the maximum applied voltage range. ds_61B05_en_js: 010611D 3 JS ## **REFERENCE DATA** ## 2.-(1) Coil temperature rise 2.-(2) Coil temperature rise Sample: 5 pcs., JS1a-24V-F Measured portion: Inside the coil Contact current: 10 A 1.
