Pulse-Contact Protection Relays with Additional DC Voltage Output Model MSR
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.
