Operate and release time excluding contact bounce. (2) Unless otherwise specified, all tests are under room temperature and humidity. (3) Consider the heat of PCB is necessary, please check the actual condition of PCB. (4) Applying no diode to this relay. The life expectancy will be lower when a diode is used. To use a varistor (ZNR) could absorb the coil surge of relay that is recommended. (5) Do not use the relay exceeding the coil rating, contact rating and life expectancy, or this may cause the risk of overheating. (6) To assure optimum performance, avoid the relay from dropping, hitting, or other unnecessary shocks. (7) Do not switch the contacts without any load as the contact resistance may become increased rapidly. (8) Use suitable harnesses and bus bars according to the current as below 2 10A typeMin. 2.0 mm 2 25A typeMin. 6.0 mm (9) Usage, transport and storage conditions !"#+70C $' *# <#=>' ?<@ J@K Y [ * \ ] [ * within the range indicated in the graph below.
