TIME MARK 261XBXPR RELAY 120

Description:

The Time Mark 261XBXPR-120 alternating relay is designed to alternate electrical loads in duplex pumping and lead/lag control applications using a 120 VAC/DC power supply. Commonly installed in wastewater lift stations, sump pump systems, water treatment facilities, and industrial pumping equipment where equalized motor run time extends equipment life. Maintenance technicians, OEMs, and control panel builders use the 261XBXPR-120 for replacement, repair, retrofit, and preventive maintenance to provide reliable pump alternation and reduce wear on primary equipment.

Applications:

The Time Mark 261XBXPR-120 is a solid-state alternating relay that changes the active output each time the control switch opens, allowing duplex pumps or other alternating loads to share operating hours evenly. It is widely used in municipal water and wastewater systems, industrial pumping stations, HVAC equipment, lift stations, and process control applications requiring dependable load alternation and improved equipment longevity.
