Overview
The Guardmaster® MSR35H/HP is a microprocessor-based, two-hand control monitoring safety relay, with safety-rated, solid-state outputs.
The input of the MSR35H/HP accepts two switches, each containing one normally open and one normally closed. Both switches must be actuated within 0.5 seconds of each other.
The MSR35 can alternatively be wired with two switches with normally open contacts to a Category IIIA application per EN 574.
The reset capability of the MSR35H/HP allows it to be set up for manual or automatic reset.
The outputs include two normally-open safety-rated outputs that can be connected to loads up to 2 A at 24V DC. These outputs can be used to send a safety stop signal to a machine or manufacturing system.
The MSR35H/HP also has one solid-state normally-closed auxiliary output, which must only be used to indicate the status of the MSR35H/HP
- Category 4 per EN 954-1
