The DOLD toggle, coupling and switch relays are the first choice for all interface applications in demanding
control systems. They connect the highly sensitive logic level of the SPS, a shelf system or process computer
with the raw operation of the power levels of a machine. Installation and maintenance of the relays can be
conducted in a time-saving manner with the snap-on plug-in sockets on the top-hat rail.
Your additional benefit: They are not sensitive to over-current and/or overloads and are significantly less
expensive that semiconductors with medium to low switching frequency.
