Safety Relays Two Hand Relays Minotaur MSR35H/HP Specifications Housing with removable terminals shown. Description The Minotaur 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 reset capability of the MSR35H/HP allows it to set up for manual or automatic start and restart. The outputs include two normally-open safety rated outputs that can be connected to loads up to 2A 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.
