ROCKWELL Automation has released a new speed monitoring safety relay, the Allen-Bradley Guardmaster MSR57P.
Rockwell says the Allen-Bradley Guardmaster MSR57P provides a complete solution to monitor all motion for small to mid-size machines and appropriate safety control, and is the first of its kind on the market.
The unit effectively combines the functionality of a speed sensing module with a configurable safety controller, according to Rockwell.
The MSR57P is designed for safety applications where access is required to guarded areas, under defined and controlled conditions, while a machine is still running.
Able to monitor up to two encoders and five dual-channel safety sensors, the MSR57P supports a wide range of safety modes, and is suited to safety applications up to SIL3 and Cat4, says Rockwell.
The unit is able to concurrently monitor motion, E-stop devices, guards, enabling switches and selection switches, and further permits monitoring of single- and multi-axis machines with one dedicated MSR57P per axis. It also supports six safety outputs and four auxiliary outputs, the company says.
