Connecting a Power Supply
Power for the GLT safety relay is provided by an external 24V DC power
supply source.
To comply with the CE Low Voltage Directive (LVD), power for the GLT
safety relay must come from a DC source compliant with safety extra low
voltage (SELV) or protected extra low voltage (PELV).
The following Rockwell Automation Bulletin 1606 power supply catalog
numbers are SELV- and PELV-compliant.
• 1606-XLP30E
• 1606-XLP50E
• 1606-XLP50EZ
• 1606-XLP72E
• 1606-XLP95E
• 1606-XLDNET4
• 1606-XLSDNET4
