The HA4890G solid state relays from Sensata are industrial mount AC output devices, designed for a wide range of applications such as automation, lighting control, electric heating, etc. It has a panel mount type with IP00 degree of protection, a 530VAC/90A AC in and zero cross LED. The low frequency (<100Hz) PNP output is designed to serve a load with less current consumption than conventional system, providing a long switch off and on period with high precision. Its maximum power temperature of 125 °C and surrounded by an aluminum base, ensures a powerful insulation between the relays and hadles high dielectric, shock and vibration strength. It is an universal AC input for voltage ranging from 85VAC to 265VAC. The relay coil works with safety reverse designed SPST-NO contacts, moreover, a filter circuit with RC value of 5.6spF, is built inside the device for providing to the contact a longer and reliable working life.
