FAQs
To install the CR-M3LSH socket, align the socket with the CR-M relay, insert the plug-in interface correctly, and secure the screw terminals with appropriate conductor sizes (2x20-16 AWG for flexible, 2x20-14 AWG for rigid). Verify 24 V AC control supply is present and that the output contacts can switch up to 250 V at 7 A. After mounting, test continuity and signal integrity. This minimizes downtime and ensures reliable operation within panel layouts constrained by narrow spaces.
Key ratings include a 24 V AC control supply, 250 V output with 7 A maximum switching capacity, and an AC-12 rating of 10 A at 230 V. The socket supports operation from -40 to +70 °C and up to 2000 m altitude, with can/csa, CE, and RoHS compliance. It uses screw terminals for durable connections and is designed for CR-M miniature relays with 3 changeover contacts.
Ideal for machine control panels, automation racks, and safety interlock circuits in manufacturing environments. Its compact 16 mm width and 69 mm height fit tight enclosures, while the 24 V AC control and 250 V output support PLC interfaces and signaling circuits common in automotive, food and beverage, and general industrial automation. The plasmic modular design also suits retrofit projects requiring quick, reliable relay socket replacements.
The socket carries UL 508 and cURus certifications, along with CE marking and CAN/CSA compliance, meeting North American and European safety standards. UKCA is also listed for certain regions, ensuring alignment with evolving regulatory regimes. This broad certification footprint simplifies supplier qualification, audits, and cross-border deployments for global manufacturers.
By enabling plug-in replacement of CR-M relays, the socket reduces downtime and spare parts inventory while speeding maintenance workflows. Screw terminals provide secure connections, lowering rework due to loose contacts. The availability of accessories such as function modules and markers supports faster commissioning and diagnostics, delivering a favorable return on investment through improved uptime and easier future upgrades.
