This module is specifically designed to provide clean, stable power to sensitive field devices or low-voltage control electronics that require an 8 V DC reference. By maintaining a low residual ripple of less than 5 mV, the KL9508 ensures optimal signal integrity for connected instrumentation, effectively mitigating noise-related errors and preventing intermittent performance issues in complex industrial automation sequences.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe KL9508 utilizes a robust terminal housing that integrates seamlessly into Beckhoff Bus Terminal nodes. It features an efficient DC-DC conversion stage that accepts a nominal 24 V DC input with a tolerance range of -15 % to +20 %. To ensure operational reliability, the module includes an integrated overcurrent protection circuit, clearly indicated by a front-mounted status LED. The terminal supports standard spring-actuated connections, compatible with the KSxxxx series for pluggable wiring, allowing for rapid deployment and simplified maintenance in dense control cabinet environments.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eKL9508\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBECKHOFF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 V DC (-15 % \/ +20 %)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e8 V DC +\/- 1 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003e0.5 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResidual Ripple\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 5 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the primary application for an 8 V DC output terminal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe KL9508 is typically used to power specialized sensors, communication transceivers, or low-voltage transducers that operate outside the standard 24 V DC or 5 V DC industrial logic levels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the KL9508 require external cooling?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo, the terminal is designed for convection cooling within a standard control cabinet environment.
