Description
Thermal Current (non switching) 1x6A, 2x4A
The MSR211P forms one of the base units for the modular
Minotaur MSR200 family of monitoring safety relays. It can be
combined with other modules of the MSR200 Series to configure a
safety control system with numbers of inputs and outputs matching
users’ specific application requirements, as well as diagnostic and
networking capabilities. Up to 10 input modules and 2 output
modules can be connected to one base unit by simply removing the
terminator, included with each base unit, and connecting the ribbon
cables of the neighboring module. The terminators must be inserted
into the final input and output modules.

The MSR211P has two inputs. Each input can be wired in one of
three ways: 1N.C., 2 N.C., or 2 PNP connections from a light
curtain. The MSR211P does not perform cross fault monitoring,
and would not detect a short across the inputs of a 2 N.C. input.
When connected to light curtains, the light curtain must perform the
cross fault detection.
Recovery Time
40-145 ms, depending on
expansion modules used

Green = Input 1 closed
Red = Input 1 open
Green = Input 2 closed
Red = Input 2 open
Green = CH1 output active
Green = CH2 output active
Green = Power
The MSR211P has the capability to perform external device
monitoring (EDM). The EDM capability works in conjunction with
the reset option. The user selects EDM and the reset function by
jumpers across terminals Y40, Y41 and Y42.
Green = Run (outputs active)
Red = Stop (outputs off) +
diagnostics
Amber = Ready (inputs closed)
The MSR211P has two semiconductor outputs designed to send
status information to a PLC. Terminal Y33 indicates the inputs are
closed (the Ready LED is on). Terminal Y32 indicates the outputs
are active.

The outputs include 2 normally open safety rated outputs and 1
normally closed auxiliary output. The safety outputs have
independent and redundant internal contacts to help ensure the
safety function.
