Description

KOBOLD Multifunctional relays, comprising power supply unit, pulse generator, isolation amplifier and switching amplifier, serve to increase the switch capacity, as the control loop is connected to low voltage. The switch capacity of reed contacts, especially when switching capacitive and inductive loads, is very often exceeded; this causes the reeds to stick – thus giving rise to dangerous faults.

A contact protection relay is used to eliminate this problem, the switch capacity and service life of the reed contacts is significantly improved. On the other hand, the KOBOLD models MSR-010 and MSR-020 have a time response. The chatter effect is thus almost totally eliminated, and no switching operation occurs when the contact opens or closes for a short period.

The switching operation is thus clearly defined. Model MSR-011 is a bistable interval relay with self-holding and is thus suitable for an interval circuit, for example for pump control. Design and construction of the contact protection relay satisfy VDE re gulations. The housing made of polyamide 6.6 can be mounted by clip-on mounting on standard mounting rail 35 x 7.5 mm, or in series, by individual screw fixing.
