Already in 1978, DOLD could introduce their first PLC in the standard housing of the automotive and machine tool industry. It goes without saying that the current-generation DOLD PLC is fieldbus-capable. An extensive range of fieldbus-capable input and output modules is also available, as peripheral modules of a PLC, for example. Coupling relays are used as connecting links between the highly-sensitive logic circuitry of a PLC and the raw operation at the machine. DOLD offers products of this kind in a variety of sizes and with different contacts.
