Hioki LR8431-20: Identifying SMD component(Relay?)
« on: March 23, 2024, 11:49:32 pm »
Hi,

This data logger has burnt out components on 2 channels, according to the board designation (RY XXX) I assume that these are SMD relays.
The marking code on this suspected relay is W210SB16, a google search turned up nothing, nothing at all. :P
Any ideas ?

My guess is they are AQW210S PhotoMOS relays from Panasonic (previously NAiS or Matsushita - thus the M logo)

Hi Kean,
Thanks, will check the datasheet "tomorrow", but that looks very promising. :-+
