Life expectancy UID - 0016R

Recommended Posts

Hello MartinIT,


Unitronics spec sheet for UID - 0016R gives a life expectancy of 100K operations.

Maximum switching current is 2A for resistive load.


To prevent wearing out the outputs, Its strongly recommended to:

- Install a flyback diode across a DC inductive load

- Install an R-C suppressor across AC inductive load


Even miniature general purpose relays, such as Omron G2R series, are producing big voltage spikes when turned off which can seriously damage your output. 


In general, when output switching frequency is high, use transistor output instead.
