Safety Configurable Relays

Programmable Relays

The Schmersal PROTECT SELECT programmable relay is an easy-to-set-up monitoring device that closes the gap between conventional safety relay modules and complex safety controllers, requiring no programming experience. This device can simultaneously monitor up to 4 separate safety circuits, replacing up to 8 individual safety relays. Each safety circuit has its own safety program. Select from 4 pre-configured programs that can be chosen and modified to meet your application needs. This module provides monitoring of all common safety sensors, including emergency stop devices, safety light curtains, safety switches, four-wire safety mats, two-hand control devices, and safe monitoring of analog signals.

• Up to 18 digital safety inputs (9 pairs)
• 4 semiconductor (OSSD) safety outputs
• 2 safety relay outputs
• 4 signaling (status) outputs
• 3 clock outputs
• Safety level up to PLe/SIL 3
• Error, status, and message log in plain text on graphic color display
• A simple multilingual configuration menu and rotary switches require no programming experience
• Models with cage clamp or screw terminal connections
• Temperature range -25°C to 55°C
