Reliance 0-52806-1F PC Board is a Tachometer Loss Overspeed (TLOB) control board from Reliance Electric, designed to monitor the drive’s tachometer input and provide overspeed protection within legacy Reliance Electric drive systems. The part is cataloged as 0-52806-1 (with the 0-52806-1F variant) and is specifically described as a Tachometer Loss Overspeed Board used to detect tachometer loss and trigger protective actions in the drive. The board typically includes LED indicators to signal status and fault conditions and is commonly deployed as a spare/refurbishment component for older Reliance Baldor drive hardware that employs the TLOB protection module.
