DESCRIPTION

The Series KD and LD solid-state relays are screened utilizing MIL-PRF-28750 test methods and are packaged in low profile hermetically sealed cases. These relays are constructed with state-of-the-art solid state techniques and feature fully floating power FET output technology. This allows the load to be connected to either output terminal and provides a low ON resistance. The input (control) and output are optically isolated to protect input logic circuits from output transients. Available options include short circuit and current overload protection, which provides complete protection for both the relay and system wiring. This feature not only provides protection should a short or overload occur while the relay is on, but will also provide protection should the relay be switched into a short. The second option is a status output line. Switch status returns the true status of the output switch and is optically isolated from the load. It provides status indication independent of the control circuit of the relay. The status line provides a logic 0 (low) when the relay output is off with load voltage and continuity present, and a logic 1 (high) when the output is on. The KD and LD series are ideal for applications switching 36, 28, 14, and 12Vdc. *The Y suffix denotes parameters tested to MIL-PRF-28750 Specifications.

Overload testing to the requirements of MIL-PRF-28750 is constrained to the limits imposed by the short circuit protection characteristics as defined in this specification. System series inductance for “shorted-load” mode of operation should be 50 μH. M aximum repetition rate into a shorted load should not exceed 10 Hz. 5. A status pull up resistor is required for proper operation of the status output. Determine the current (Iso) required by the status interface. Calculate the current (Is) through the status resistor such that the sink current through the status output is 0.6 mA. Select the status resistor such that it does not allow more than 0.6 mA to flow through the status output. R STATUS = ( VSTATUS - 0.4V ) / Iso 6. Inductive loads should be diode suppressed. Input transitions should be ≤1 ms d uration and the input drive should be a bounceless contact type. 7. Parameter Guaranteed by design, but not tested 100% in product acceptance.
