Manufactured by Rockwell Automation and made in Germany, this unit operates on a 24V DC, 3W supply and monitors motor standstill by measuring the induced back EMF voltage across two redundant channels. When both channels simultaneously detect a voltage drop to zero, the output relay energizes to indicate standstill. The adjustable voltage threshold accommodates different motor types, and the adjustable delay time (Ts) allows integration across a range of applications.\u003c\/p\u003e\n  \u003cp\u003eThe contact output configuration consists of 3 N.O. safety contacts and 1 N.C. auxiliary contact, rated B 300 pilot duty. At 40°C, contacts are rated 5A 250Vac G.P. and 5A 24Vdc; at 60°C, ratings are 2A 250Vac G.P. and 2A 24Vdc. The unit carries UL Listing for industrial control equipment (4B51), CE marking, EAC certification, and TÜV certification as visible on the nameplate. Terminal connections are removable screw type and spring clamp. Lot number 2023\/04\/24 28195 and PN 533949 are visible on the product label.
