This is a twopiece pack of SLA18VDCSLC relays, each with a 30A contact rating and an 18V DC coil. The T90 variant uses a 5pin configuration with common, normally closed, and normally open contacts. Designed for 18V DC control circuits, these relays are a practical conversion solution for welding equipment and similar applications. Key benefits current switching: each relay supports up to 30A, enabling reliable control of heavy loads. 18V DC coil compatibility: specifically suited for control circuits powered by 18V DC, common in welding machines and other equipment. Dualrelay pack: two identical relays in one provide two switching channels or a spare unit for redundancy. Flexible contact arrangement: 5pin design with common, normally open, and normally closed contacts allows versatile wiring options for control and load circuits. Ready for 18V DC conversion use: marketed as an 18V DC conversion type suitable for replacing or implementing 18V control relay functionality in compatible systems. Key attributes Brand/model: SLA18VDCSLC Coil voltage: 18V DC Contact rating: 30A Pin count: 5 pins per relay (typical SPDT configuration with common, NC, NO) Configuration: 2 relays per pack (2PC) Application scope: intended for current switching in 18V DC circuits, including welding machines and similar equipment Performance and compatibility Suitable for switching 18V DC loads up to 30A per relay, enabling dependable operation in control and automation scenarios. Follows the SLA18VDCSLC series specifications, ensuring compatibility with common 18V control circuits and replacement parts. Use cases Welding machine control: or implement the switching function for a current load driven by an 18V DC control line, using the two relays for dual circuits or redundancy. 18V DC motor or actuator control: drive a 30A DC motor, pump, or actuator from an 18V control signal, utilizing the SPDT contacts for on/off switching with a defined OFF state. Dualchannel control or modular panels: wire two independent 18V DC loads in a single package, enabling compact, twochannel control in automation or test rigs. Note: This description reflects the product's stated features—two 30A, 18V DC coil relays in a 5pin SLA18VDCSLC format—without adding specifications beyond what is provided in the product title.
