RC Series PCB Relays IDEC RC Series PCB Relays feature low-profile, high-capacity, and compact relays. These relays provide multiple options for operating voltages and extended electrical and mechanical life. The PCB relays operate at -40°C to 85°C temperature range and 10Hz to 55Hz frequency range. These RC relays consist of a 110VDC operating coil voltage and flux resistance type (RTII). The RC series PCB relays are UL, c-UL, VDE, and CQC-certified products. These low-profile relays are 12.8mm x 16.5mm in dimensions. The RC series PCB relays are UL, c-UL, VDE, and CQC-certified products. Typical applications of these relays include industrial equipment, control high temperatures, and are suitable for small equipment.
