In-rush current in DC solenoids explained
DC solenoids are an inductive load that present a momentary short to it's driver circuit. For example even a small 6W 24V DC that has a steady state current of 250 mA will have an in-rush current of 750mA to 1A. This in-rush current could last only a few µs but the output transistor or Mosfet driving it needs to have a capability of handling 1A. Therefore a prudent automation engineer will put in an external solid state relay to drive this DC solenoid. A typical solid state relay (such as Crydom) will cost $57 for each SSR and there would be at least a lobor cost of $5 to mount and connect each solid state relay.
Now solid state relays are not short circuit proof leaving the Automation engineer no choice but to put a fast acting fuse in series with the coil of the DC solenoid costing additional material and labor.
Each PLC output driving a DC solenoid will cost at least additional $75 per output.
On first glance it would appear that the problem is solved even though it costs substantial additional money, but these fuses present a maintenance problem in that the engineer/technician troubleshooting it has to find this fuse and replace it in case the solenoid shorted.
7. Unique Patent Pending High Current (HC) DC Output modules for DC solenoids and Fans with Surge Current saving a lot of cost.
These High Current (HC) modules are specified to carry 1 Amp Steady State current to drive 24W solenoid and 4 Amp Surge current for 20 milliseconds. These DC inductive loads have 3-4 times in-rush current needing external solid-state relay, that costs $, Panel space and labor and yet no Short Circuit Protection. For short circuit protection, AutomationDirect recommends adding fast acting fuses for each output. No such need with HC Modules.
