Si5SDOI2-50V-2x16A, Spec Sheet (PDF) |
The Si5SDOI2-50V-2x16A is a Dual, 50V 2x16A Solenoid Driver with an integrated heat sink that uses two independent optically isolated digital control voltages VI1,G and VI2,G (0 to 15V) to turn two load-currents on or off. This board requires a single 6V to 50V DC power source (unregulated and unfiltered) at a 0A to 40A current range to operate normally with a wide range of inductive loads (coils or Solenoids). The digital control inputs are zener-diode protected and optically isolated from the power source Vp (with a breakdown voltage of 1000V) and each requires only 2mA input current at VIn,G=5V to fully turn on a load current. Each load current is off (zero) when its corresponding control voltage VIn,G is: 0< VIn,G<2.5V and the load current is on (max.) when 2.5V< VIn,G<15V. Snubbing circuits and filter capacitors are included to suppress inductive switching transients. Two onboard LEDs (Red and Green) are used to monitor the load-voltages A small (2.3”x2.4”x0.95”) finned integrated heat sink is included with mounting hardware (as shown on the photograph) to operate at 2x16A or 1600W power levels. Higher power-levels (50V, 2x20A or 2000W) can be achieved with more efficient heat-sinks. Please click on this link and read the Board Mounting Instructions and Heat Sink Selection Guide. Typical applications are: Dual Inductive-Plunger Driver, SPDT Solid State Relay, etc. This board can be configured to perform efficiently in many customized applications.
A Typical Application of the Si5SDOI2-50V-2x16A
In this dual application, two high-current (16A at 50V) inductive loads (coils or solenoids) are turned on and off respectively by the optically isolated Digital Control Voltages VI1,G and VI2,G. A load current is off (zero) when its corresponding control voltage VIn,G is: 0< VIn,G<2.5V and the load current is on (max.) when 2.5V< VIn,G<15V.
