Configurable safety relay Mosaic | ReeR

Programmable safety relay | ReeR Mosaic

The capabilities of the configurable safety controller 'Mosaic' of ReeR are no longer limited to the basic functions as an emergency stop or two-hand control. The Mosaic is practically applicable for most security issues. Read more about programmable safety relay ReeR Mosaic.

A Mosaic system realizes

  • Reduction of the number of components and wiring
  • Rapid assembly of complete security
  • Simple logic functions programmable with simple software
  • Reliable setting up a security system

Besides the basic controller (equipped with, inter alia, eight inputs and two dual outputs) the Mosaic can be extended with o.a .:

  • Speed monitoring (MV)
  • Directly controllable relay contacts (mor4 / mor4 S8)
  • Configure Remote I / O without (MCT)
  • Bus modules (among others Profibus, EtherCAT, CANopen, etc.)
  • Various I / O modules

Features programmable safety relay

Configurable safety relay - SIL3 / PLe
Reer Mosaic is a modular, configurable safety relays for protecting machines or plants to a safety level PLe / SIL 3.

Speed monitoring
With the MV-module, the speed of a machine can be monitored at a standstill, maximum speed and direction. By applying the Safecoder (safe encoder) can be achieved with a single encoder, the maximum level of safety.

Relay contacts
The base unit M1 is equipped with two safety OSSD outputs (both in duplicate). If relay contacts are required, can be connected to a relay unit (same design) to convert the OSSD to relay contacts. Another possibility is to extend the I / O directly with controllable relay contacts. The mor4 contains four directly controllable safety contacts, the mor4 S8 also features eight programmable signal outputs.

Remote I / O
With the MCT units can I / O units are placed at a distance while it is still an integral part of the safety controller. The maximum distance between two MCT units is 50 m, the total distance: 250 m..

Bus modules
A Mosaic system can communicate with the outside world through a bus module. The bus modules are available for the most common industrial fieldbus systems:

  • Profibus DP (MBP)
  • DeviceNET (MBD)
  • CANopen (MBC)
  • Ethernet IP (MBEI)
  • EtherCAT (MBEC)
  • PROFINET (MBEP)
  • Universal Serial Bus (MBU)

Expandings
A Mosaic system can be expanded with up to 14 I / O Units and thus achieves total (maximum): 128 Entries, 16 OSSD (pairs) outputs, 16 feedback / restart status inputs and 32 outputs.

The I / O units that are currently available:

  • MI8O2 (8 IN, 2 OUT)
  • MI8 / MI16 (8/16 inputs)
  • M12T8 (12 IN, 8 test outputs)
  • MO2 / MO4 (2/4 OSSD Output Save)
  • MR2 / MR4 (2/4 relays 2/4 NO + 1/2 NC connectable: 1/2 + 1/2 OSSD pair NC contact for External Device Monitoring (EDM)

Mosiac is configurable via the MSD (Mosaic Safety Designer) graphical interface that is provided at no additional cost with each base unit.

  • IEC / TS 62046 Ed. 2 "Safety of machinery - Application of protective equipment to detect the presence of persons"

Many new features
The Mosaic of ReeR has been enhanced with new functionality in the configuration software and with five new expansion modules.

Software: "Inter Page Operator" for Mosaic MSD
MSD software release 1.3.4 integrates a new feature: "Operator Interpage" which connections can be made in the schedule without drawing the connection. This Operator Interpage be large schemes even clearer.

New expansions
The expanders three fieldbus and two speed monitoring modules have been added:

Fieldbus

  • MBEI2B Ethernet IP module with two connectors
  • MBMR ModBus RTU module
  • MBEM ModBus TCP / IP module

Speed monitoring

  • MV1TB expansion modules for safety speed monitoring: 1 TTL input for 24 VDC incremental encoder and two PNP / NPN proximity switches.
  • MV2TB expansion modules for safety speed monitoring: two TTL inputs for 24 VDC incremental encoders and 2 PNP / NPN proximity switches.
