SC75-2SH Teledyne

Series C75 Optically Isolated 1.0A with Short-Circuit Protection & Trip Status DC Solid-State Relay FEATURES/BENEFITS Short Circuit Protected: Prevents damage to system components, assemblies and system wiring Trip Status: Provides status monitoring and feedback of the protection state Optical Isolation: Isolates control circuits from load transients Eliminates ground loops and signal ground noise Low Off-State Leakage: For high off-state impedance Switches High Currents: To 1.0 Adc High Dielectric Strength: For safety and for protection of control and signal level circuits DESCRIPTION The C75-2S solid state relay utilizes a power FET switch that is protected against overload and short circuit currents. Protection is provided against turn-on into a short circuit, shorts that occur while conducting loads up to rated or for long term overload currents above rated that slowly overheat the relay. Once the protection trips the relay off it will remain off until reset by cycling the input control. Using the C75-2S to switch power loads can prevent res, damage to system assemblies and system wiring. The power FET output offers low On resistance and can switch loads in either the high or the low side of the power line. The C75-2 is packaged in a 16 pin DIP, with surface mount or through hole mounting available. The C75-2SH also provides an open collector trip status feedback to the relays control side for short circuit and thermal trip monitoring. H = Relay has an internal over voltage suppressor for inductive loads. 2004 TELEDYNE RELAYS (800) 284-7007 www.teledynerelays.com C75 1 C75 112004 Q1Series C75 ELECTRICAL CHARACTERISTICS 3.5 3.0 2.5 TYPICAL 2.0 40C 1.5 TYPICAL +25C +85C 1.0 0.5 0 TRIP TIME (SECONDS) TYPICAL TRIPP CURRENT VS.
