The SV9Z-SA2W is a spacer (circuit separator) accessory designed for use with IDEC's 6mm and 14mm slim interface relay modules. This 2mm-wide spacer is used to separate relay circuits and is typically employed when using cut jumper combs to maintain proper spacing and isolation between adjacent relay positions. The spacer dimensions are 71.4 mm × 66.8 mm × 2.0 mm, making it compatible with both 6mm and 14mm relay widths in the RV8 series. It is commonly used in relay panel configurations where modular relay stacking and circuit separation are required, particularly when custom jumper lengths are needed for specific control applications.
