Example: Optical isolation SCD00CFW Low profile hermetic ceramic package Built and tested to the requirements of ELECTRICAL SPECIFICATIONS MIL-PRF-28750 (-55C TO +105C UNLESS OTHERWISE NOTED) DESCRIPTION INPUT (CONTROL) SPECIFICATION This all solid-state relay utilizes the When used in 2 terminal configuration latest technology to provide a low ON resistance. The control (input) and load (TTL or direct control) (See Fig. 1) Min Typ Max Units (output) are optically isolated to protect input logic circuits from voltage and Input Current V = 5 Vdc (See Fig. 2) 14 15 mA IN current transients which can occur on the output supply. The optical isolation Turn-Off Voltage (Guaranteed Off) 1.5 Vdc also provides a full floating output, thus allowing the load to be connected to Turn-On Voltage (Guaranteed On) 3.8 Vdc either output terminal. The control circuit is buffered to enable the relay to be Reverse Voltage Protection -32 Vdc driven directly from standard CMOS or open collector TTL logic circuits. Input Supply Range (See Note 4) 3.8 6 Vdc Available options include short circuit and current overload protection, which INPUT (CONTROL) SPECIFICATION provides complete protection for both the relay and the system wiring. This When used in 3 terminal configuration feature not only provides protection (CMOS or open collector TTL) (See Fig. 1) Min Typ Max Units should a short or overload occur while the relay is on, but will also provide Control Current protection should the relay be switched V = 5 Vdc 250 A into a short. In either case, the relay will CONTROL sense the short circuit condition and V = 18 Vdc 1 mA CONTROL then block it indefinitely until the short is removed and the unit is reset by cycling Control Voltage Range 0 18 Vdc the input control. The second option is a status output, which provides a built-in- Bias Supply Voltage (See Note 4) 3.8 6 Vdc test function. This feature checks the input circuitry of the relay and provides a Bias Supply Current V = 5 Vdc 14 15 mA BIAS logic (0) low when the input circuit is turned on and operational. Both options Turn-Off Voltage (Guaranteed Off) 3.2 Vdc are available either together or separately as standard features.
