Sensor isolation
Compact and powerful solid-state relays for isolation sensor signals
In order to reliably decouple sensor signals from the field, space-
saving and fast-switching coupling elements are required. We offer
special solid-state relays for sensor isolation, as well as relay modules
with gold-plated contacts for reliable switching of small currents and
voltages, as they typically occur when switching sensor signals.
Solid-state relay for sensor isolation
As there is often a high number of switching cycles in sensor isolation,
it makes sense to use solid-state relays. They have no mechanical wear
and therefore work reliably in the long term. Our solid-state relays are
extremely compact and, thanks to suitable accessories, enable quick
installation. By using TERMSERIES interface adapters in conjunction
with pre-assembled cables, the wiring time can be reduced further.
Electromechanical relays with gold contacts
In applications where sensor isolation is only carried out at longer intervals
and with low power (<30V/10mA), oxide layers can form on the contacts.
This usually occurs in applications where signals are forwarded to control
inputs or PLC systems. Due to the low loads, there is not enough light arcing
at the contacts to remove the oxide layer during switching. Therefore,
relay modules with oxidation-resistant gold contacts are used.
