High Reliability, DC Solid State Relay

Transcription

1 High Reliability, DC Solid State Relay esigned for the highest levels of reliability, the Cole R-series D Solid State Relay has no moving parts, making it immune to all contact related problems such as contamination, arcing erosion, and bouncing associated with electromechanical relays. The R-series operates as an SPST, normally open ( Form A) switch. Its circuitry is encapsulated in a non-hermetic plastic package and is suitable for PC mount applications. It is configured for switching DC current and can be operated as a unidirectional high-side or low-side switch. Cole s R-Series employs an optocoupler as an optical isolation barrier between its control input and output (load) that eliminates the system ground loop noise. The control input that actuates the switch contains a light emitting diode (LED) with low forward voltage and current. This low power LED is compatible with most TTL and CMOS devices. The output circuitry contains at least one MOSFET with low onstate resistance to minimize its internal power dissipation over the operating temperature range of -0 C to 85 C. Therefore no heat sink is required for applications where the R-Series is operated within its specified ratings. The Cole R-Series Solid State Relay is ideal for COTS military applications, avionics, industrial automation, programmable logic controllers, office and test equipment, and motor, solenoid, display, and lamp drivers. Quality construction and exceedingly stringent manufacturing processes, inspection and testing, ensure the R-Series will meet the demands of your most challenging applications.

Guaranteed, but not tested.. Applying appropriate transient suppression technique between output terminals would be necessary for inductive loads.. Times are measured as follows: Rise time: from to 9 of load current (or 9 to of output voltage). Fall time: from 9 to of load current (or to 9 of output voltage). Turn-on time: from 5 of the rising edge of the input foward current to 9 of load current (or of output voltage). Turn-off time: from 5 of the falling edge of the input forward current to of load current (or 9 of the output Voltage).. Test voltage should be applied momentarily, not a steady state operating condition.
