Lovato 31L48MM240 Multifunction Time Relay 24-240 V AC/DC
Description
A multi-voltage multifunction timer in a 48 mm plug-in housing
The 31L48MM240 is an electronic multifunction time relay from Lovato Electric with a 48 x 48 mm plug-in housing. A single unit covers supplies from 24 to 240 V AC or DC, so one part number can serve several control voltages in a panel, and the time range is selected with DIP switches and set on a front knob.
Selectable functions include on-delay, pulse on energising and two flasher modes, with an external reset input and a stop input that stores the elapsed time. Two relay outputs each provide a changeover contact, and both are delayed. It plugs into an 11-pin socket and can be flush-mounted in a door with the optional bracket. The data below comes from the Lovato catalogue.

Functions and settings
The catalogue lists the selectable functions as delay on make, pulse on energising, and flasher starting with either the OFF or the ON interval. A reset contact on terminals 7 and 6 resets the relay, and a contact on terminals 7 and 5 stops timing and keeps the elapsed time until it is opened again. LEDs show power on and relay state. The sister model 31L48MH240 covers longer ranges from 0.05 min to 10 h.
Sockets and ordering
The relay needs an 11-pin socket. Lovato lists the HR7XS2 socket for screw or DIN-rail fixing and the 31L48P11 loose socket with the 31L48AP flush door-mounting bracket. The sockets are rated 10 A, 250 V AC with a maximum conductor section of 2 x 2.5 mm2. Please confirm the control voltage and the required function and time range before ordering. The Lovato web page lists weight as 135 g in the data sheet and 134 g in the logistics data. Browse more automation accessories or send us your requirement.
