Low Signal Relays CUI Devices Low Signal Relays are ideal for applications in need of low-level current switching with maximum switching currents of 2A or 3A. CUI Devices Low Signal Relays feature SPDT (1 Form C) or DPDT (2 Form C) contact forms, contact ratings of 120VAC, 125VAC, or 24VDC at 1A, and AuAg overlay contact material. These signal relays carry coil power ratings from 150mW to 450mW and coil voltages from 3VDC to 24VDC. With maximum switching voltages of 120VAC, 125VAC, 220VAC, or 30VDC, 60VDC, these signal relays can be used in industrial devices, test and measurement equipment, security systems, and more.
