Relay amplifier board | Transistor amplifier board | |
Response speed | >10msMore than 10ms | The response speed is as fast as 0.5ms and more than 10 times per minute. It is recommended to use transistor type amplifier |
Service life | The greater the current, the shorter the service life, generally between hundreds of thousands and millions of times, subject to the relay mechanism.械结构 | Compared with relays, it has a longer lifespan and only ages, with no limit on the number of uses. |
Load Capacity | Depends on the relay used, the load capacity is generally 5A rated current | Using high-power transistors, the load capacity is the same as that of relays |
Space usage | Requires a larger location for installation | The space used is about ⅓ of the relay amplifier board |
Wire outlet method | Complex wiring | Compatible with DC24V positive and negative input, flexible wiring. Output NPN, PNP optional |
Cost-effectiveness | Relays are expensive and have a short lifespan | The price per channel is half of the relay amplifier board, with a longer service life, more stability, faster speed, and less worry for customers. |
