The control (input) and load (output) are optically isolated to protect input logic circuits from voltage and current transients which can occur on the output supply. The optical isolation also provides a full floating output, thus allowing the load to be connected to either output terminal. The control circuit is buffered to enable the relay to be driven directly from standard CMOS or open collector TTL logic circuits. Available options include short-circuit and current overload protection, which provides complete protection for both the relay and the 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. In either case, the relay will sense the short-circuit condition and then block it indefinitely until the short is removed and the unit is reset by cycling the input control. The second option is a status output line. This feature is available in either switch status or trip status configurations. 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 input circuit is off and load circuit continuity is present. The status line provides a logic 1 (high) when the output is on. Trip status, available only with HD24 Series relays, returns a logic 0 (low) if the output trips off and a logic 1 (high) when the output is in a normal mode (on or off). These options are available either together or separately as standard features.

Control input is compatible with CMOS or open collector TTL (with pull up resistor). For bias voltages above 6V, a series resistor is required. Use the standard resistor value equal to or less than the value found in Figure 8. 2. The rated input voltage is 5V for all tests unless otherwise specified. 3. Transient blocking voltage test is performed per MIL-STD-704 (28 Vdc systems). 4. To calculate the maximum ON resistance for a given junction temperature, find the normalized ON resistance factor (NR) from Figure 4. Calculate the new ON resistance as follows: R(ON) = NR • RON @ 25°C 5. 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 30 mH MAXIMUM. Maximum repetition rate into a shorted load should not exceed 10 Hz. 6. 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. VSTATUS - 0.4V RSTATUS = 0.6 mA - Iso 7. Inductive loads should be diode suppressed. Input transitions should be ≤ 1 ms duration and the input drive should be a bounceless contact type. HD 48 SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE © 2002 TELEDYNE RELAYS HD\072002\Q1
