The Relpol RM87N-2011-35-1012 is a general-purpose electromechanical relay with a 12 V DC coil and one changeover contact (1 CO, SPDT). In the de-energised state, the common contact is connected to the normally closed (NC) contact. When the coil is energised, it switches to the normally open (NO) contact and returns to its original position when the coil is de-energised.
It uses AgNi contacts. The rated load is 12 A / 250 V AC in AC1 and 12 A / 24 V DC in DC1. For inductive loads, motors or other utilisation categories, the corresponding ratings must be observed, as the switching capacity may be lower than for resistive loads.
The relay can be mounted directly on a printed circuit board (PCB) or used with a compatible socket. The RM87N version has a 3.5 mm terminal pitch and an IP67 cover protection rating.
The relay must be selected, connected and used within the limits specified by the manufacturer. Installation and servicing must be carried out by qualified personnel; incorrect connection may cause malfunction, excessive heating and a risk of fire.
