The Allen-Bradley 1606-XLSRED is a redundancy module from the Bulletin 1606-XLS series, designed for use in industrial 1+1 or N+1 redundancy systems. It features two input channels compatible with power supplies rated up to 10 Amps and a single output channel that can handle nominal currents up to 20 Amps. Operating within an input voltage range of 24 to 28 Volts DC, the 1606-XLSRED provides reliable power backup for automation systems and industrial applications. Unlike some redundancy modules, it does not include monitoring circuitry, focusing instead on compact and efficient redundancy performance.
