Product Data Sheet
8501RS miniature plug in relays are designed for use in Class 1 Division 2 hazardous locations. These relays are designed to be plugged into a relay socket. This makes for very easy replacement. This relay plugs into an 8501NR45 or 8501NR45B relay socket. Relay is available with 4PDT contact arrangements. It has four normally open and four normally closed contacts. The contacts have a 5 ampere resistive rating at 240 VAC, at 120 VAC and at 30 VDC. Relays can be ordered with a wide variety of coil voltages. This relay has a 24 VDC nonreplaceable coil. Relay does not have a green LED indicator. 8501RS relays are UL listed with Square D relay sockets, UL component recognized and CSA certified.
