BD AC DESCRIPTION The RA series of solid state relays (SSRs) is designed for use in AC power switching applications where safety and reliability are primary concerns. These SSRs are rated for load voltages up to 250 Vrms from 40 to 440 Hz and are ideal for resistive and reactive loads with power factors as low as 0.2. Inverse parallel SCRs are configured for zero voltage turn on and can handle current surges up to 100 A. Optical isolation to 1500 Vrms between the control (input) and load (output) allows the load to be safely controlled by logic circuitry. The RA series is available with thermal protection and thermal TRIP status. In case of a thermal runaway condition, the SSR will shut down the output switch and latch off until the input is reset and the junction temperature returns to a safe level. When the output does latch off, the TRIP status line will yield a logic level output indicating the protection state of the SSR. This feature provides the user with failure mode indication while enhancing the system diagnostic capability. These SSRs are packaged in low profile hermetically sealed cases.

Control input is compatible with CMOS or open collector TTL (with pull up resistor). 2. For bias voltages above 6 Vdc, a series resistor is recommended. Use a standard resistor value equal to or less than the value found from Figure 5. 3. Unless otherwise noted, the input voltage for functional tests shall be 5 Vdc. 4. Transient suppression must be used to limit the voltage to < 500 Vpeak when switching inductive loads. Load voltage must be applied before turning ON an inductive load. 5. Control input implies presence of bias voltage. DC A D SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE AC-12 25
