Description
The MSR221P is an input expansion module for the modular
Minotaur MSR200 family of monitoring safety relays. It can be
connected to either the MSR210P or MSR211P to provide
additional inputs.
Up to 10 input modules can be connected to a base unit by simply
removing the terminator, included with each base unit, and
connecting the ribbon cables of the neighboring module. The
connecting ribbon cable provides power to the MSR220P as well as
a check on its status. The terminators must be inserted into the final
output module. The input modules to a base unit can be either
MSR220P or MSR221P in any combination or order.
The MSR221P has two independent inputs, which can be wired in
one of three ways: 1N.C., 2 N.C. or a light curtain. When connected
in the 2 N.C. configuration, the MSR221P does not perform cross
fault monitoring (i.e., checks for shorts between the 2 inputs).
Four LEDs provide status information on the inputs. Green
indicates the input is closed and red indicates the input is open.
