FEATURES
• Fast Switching Speed: Where speed is important
• Floating Output: Eliminates ground loops and
signal-level ground noise.
• Low Off-State Leakage Current: High offstate
impedance
• High Dielectric Strength: For safety and
protection of signal-level circuits.
DESCRIPTION
The 603-1 and 603-2 optically coupled solid-state
relays are rated at 2 Adc and 5 Adc at 50 Vdc,
and are available with TTL compatible inputs.
Packages are available in three different
configurations with a choice of screw terminals,
quick disconnect terminals or through hole solder
pins. This allows for maximum flexibility for
mounting onto printed circuit boards, panels, or
heat sink mounting with optimal mechanical and
thermal considerations.
The 603-3 and 603-4 relays were designed
specifically for high-voltage loads up to 5A at 250
Vdc. They utilize a Teledyne transformer coupled
driver/isolator to provide high input/output isolation
and low offstate leakage. The adaptive package
design offers a choice of screw or quick
disconnect terminals for chassis, panel, or heat
sink mounting, and solder pins for direct mounting
on PC boards.

NOTES
1. The basic part number provides for screw terminals only.
To order PC mounting pins, add suffix “P” to part number.
For quick-disconnect terminals, add sufffix “Q” to part
number.
2. Relays mounted on heat sink with silicon grease.
3. Rise and fall times of input signal must be less than 1 ms or
damage to output stage may result.
4. All electrical parameters at 25°C unless otherwise
specified.
