Introduction
|
|
| Our CYDO 48HV digital output-only high-voltage direct-drive board acts like a
set of nonisolated solid-state relays--each circuit is an NPN Darlington
transistor configuration. All outputs are open collector and incorporate
clamping diodes for transient protection. Because there is a small amount of OFF
current flowing, like a solid-state relay, the HV is not ideal for switching
very low-level signals. If you have a circuit that is suitable for solid-state
relays and does not need isolation, then this might be the answer. The ability
to withstand transients, connect directly up to 50V, and sink as much as 500mA
make the HV ideal for controlling lamps, relays, printer hammers, and similar
loads. |
