Approvals and Conformity
The safety approval, performed by TÜV Rheinland is available on
www.ab.com. The actual list of relevant safety data and applied standards
is given in these documents.
MSR42, MSR41 or MSR45E units can only
achieve their function as a safety
controller module, if the instructions
given in this instruction manual and the
within mentioned documents are exactly
followed, as well as consulting the valid
laws and regulations at the time of
installation. Should these instructions not
be carefully followed, serious injury or
death may occur. The installer or system
integrator is responsible for a safe
integration of this product. This
instruction manual is to be used in
conjunction with the MSR42, MSR41 and
MSR45E module. It must be kept
accessible together with the other
machine documentation during its entire
life cycle for all personnel responsible for
assembly, installation, operation and
maintenance.
Introduction
The MSR4x is a family of compact safety modules. The main controlling
module allows the connection and the control of the GuardShield
Micro400 safety light curtain systems (Figure 1). Depending on the
configuration, other safety components can also be connected and
monitored simultaneously.

Figure 1: MSR42 controller with all safety components which can be connected (depending
on individual configuration)
Both the MSR42 and MSR41 offer two safety PNP outputs. Additional
safety relay expansion modules can be applied for applications, which
require more outputs (MSR41 or 42) and/or dry contacts (MSR45e) to
switch loads. Up to three expansion modules can be controlled and daisy
chained to one main module.
In addition to the expansion relays, models are offered in special
configurations which are described in the appendix at the end of this
manual.
