Acc24E3 Amp Enable Relay
#2
(07-18-2018, 07:16 AM)JeffLowe Wrote: Three times in the past few weeks we have had failures of the Amp Enable on the Acc24E3 cards at three different customer sites. These are operating Glentek and Trust drives, both at TTL levels with internal 10k pullups to 5V. These machines have been functioning normally for periods up to two years. Are these physical relays, and if so, what is the MTBF/MTTF?

We have seen similar failures on Acc-24E3 boards: on the amplifier mezzanine card, the 'Clare LBA716 Dual Single-Pole OptoMOS® Relays Normally Open & Normally Closed' relays have failed. Most of the systems have been running for years without problems.
