MSR200 Modular Safety Relays
|
Features/Benefits
Using plug-and-play digital I/O expansion modules, the MSR200 expandable modular relay system supports up to 22 diverse inputs (mats, light curtains, switches, etc.) to allow safety control of larger, more complex manufacturing equipment with a single relay system. The MSR200 family’s microprocessor-based design offers enhanced diagnostic and communication functionality over multiple protocols. It also allows the relay to deliver output and error status over a fieldbus network to an HMI. Simple plug-in connectivity between modules provides simple system expansion with reduced wiring. Offering SIL3, delayed output support and an optional dedicated display module, the MSR200 system provides substantial cabinet space savings over dedicated single-function relays.
Applications
- Wide range of general purpose applications
- Automotive
- Packaging
- Food and beverage
- Semiconductor
- Material handling
- PLC controlled applications
- Medium size machines
Common Misapplications
- Dedicated input connections for input devices
- Not economical when communication is needed (MSR300 recommended)
MSR300 Configurable Safety Relays
|
Features/Benefits
The MSR300 family of expandable modular safety relays handles larger, more complicated safety systems by allowing connection of multiple input modules to a single base unit. It offers a logic configuration with multiple inputs and the control of multiple independent outputs. The system supports up to 20 diverse inputs and can control up to 3 zones, performing simple function block logic configurations through rotary switch settings as opposed to software configuration. Modules can be mixed and matched to work with various input device types, reducing the need for multiple single-purpose relays, simplifying setup, wiring, maintenance and saving valuable panel space. The MSR300’s diagnostic capabilities over multiple protocols provide input, output and error status. Offering SIL3, two-hand control support and monitoring through HMI, the MSR300 is easily customized and expanded thanks to plug-in connections that reduce wiring for the addition of inputs and outputs.
Applications
- Wide range of general purpose applications
- Automotive
- Packaging
- Food and beverage
- Semiconductor
- Material handling
- Wide variety of input types
- Reduced inventory
Common Misapplications
- Single zone applications with no communications requirements
