Connectors / Cables / Terminal Blocks

If control systems with integrated switching outputs reach their limits in the application, coupling relays and contact extension modules are used. Their task is contact amplification, contact multiplication and, due to the galvanic isolation between input and output, decoupling of the control and power levels. The centrepiece of the extension module RK 6929 of the SAFEMASTER series, which is only 17.5 mm narrow, is the safety relay OA 5642 from Dold, which also opens up fields of application in the area of functional safety up to Cat. 4 / PL e or SIL 3 due to its forcibly guided contacts in accordance with IEC 61810-3.
