Latching / interface / switching relays

Latching / interface / switching relays

Links between logic and load

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 overcurrent and/or overloads and are significantly less expensive that semiconductors with medium to low switching frequency.
