Review: Does the job perfectly - Good quality, you can choose high and low trigger voltage. Terminals could be a bit bigger. Well-packed, individually in antistatic bags.
Review: Good value - These relays work well with both high and low level inputs. One thing that lets them down is the quality of the screw terminal blocks - I have seen better.
