OVERVIEW
MOSAIC is a modular safety controller. It consists of a master unit (MOSAIC M1,
MOSAIC M1S or MOSAIC M1S COM), which can be configured using the MSD
graphic interface, and a number of expansion units connected to the main unit via
the proprietary MSC bus.
The MOSAIC M1, MOSAIC M1S, MOSAIC M1S COM can also be used as a stand-alone
device and they are equipped with:
• MOSAIC M1: 8 safety inputs, 2 independent programmable dual channel
safety outputs (OSSD) and 2 SIL 1/PL c outputs
• MOSAIC M1S: 8 safety inputs, 4 independent programmable single channel
safety outputs (OSSD) and up to 4 SIL 1/PL c outputs
• MOSAIC M1S COM: 8 safety inputs, 4 independent programmable single
channel safety outputs (OSSD), up to 4 SIL 1 / PL c outputs and enhanced
communications features (see "MOSAIC M1S COM key features").

The following expansions are available: I/O expansions (MI8O2 and MI8O4 (MI8O4 with
MOSAIC M1S, MOSAIC M1S COM only)), input expansions (MI8, MI12T8, MI16), output
expansions (MO2, MO4 and MO4LHCS8 and MO4L (MO4L for MOSAIC M1S, MOSAIC M1S COM
only)), SIL 1/PL c output expansions (MOS8 and MOS16), guided contact safety relay output
modules (MR2, MR4, MR8, MOR4 and MOR4S8), encoder and proximity input expansions (MV2,
MV, MV0), modules with analog inputs (MA2, MA4 only for MOSAIC M1S, MOSAIC M1S COM)
and diagnostic connections to the main fieldbuses: MBP (PROFIBUS), MBC (CanOpen), MBD
(DeviceNet), MBEI (ETHERNET/IP), MBEP (Profinet), MBEC (ETHERCAT), MBMR (Modbus RTU),
MBEM (Modbus/TCP) MBCCL (CC-link).
MOSAIC is capable of monitoring the following safety sensors and commands:
optoelectronic sensors (safety light curtains, scanners, safety photocells),
mechanical switches, safety mats, emergency stops, two-hand controls, all
managed by a single flexible and expandable device.
Master MOSAIC M1 / MOSAIC M1S / MOSAIC M1S COM
The system must consist of just one Master MOSAIC M1, MOSAIC M1S, MOSAIC M1S
COM and a number of electronic expansions that can range from 0 to a maximum
of 14, not more than 4 of which of the same type. There is no limit to the number
of relay modules MR2 e MR4 that can be installed.
With 14 expansions, the system can have up to:
• with MOSAIC M1: 128 inputs, 16 safety outputs and 32 SIL 1/ PL c outputs.
• with MOSAIC M1S, MOSAIC M1S COM: 128 inputs, 32 safety outputs and 48
SIL 1/ PL c outputs.
MASTER and its SLAVE units communicate via the 5-way MSC bus (ReeR proprietary
bus), physically arranged on the rear panel of each unit.
Furthermore, by means of MBx Fieldbus interfaces or MOSAIC M1S COM or both,
are available:
• All inputs states (with diagnostics)
• All safety outputs states (with diagnostics)
