Power, Ground, and Wire
Connect a Power Supply
An external 24V DC power supply source must provide power for safety relays.
To comply with the CE (European) Low Voltage Directive (LVD), a DC
source compliant with safety extra low voltage (SELV) or protected extra low
voltage (PELV) must power the safety relays. Bulletin 1606 power supplies are
SELV- and PELV-compliant.
shows the power supply connections. The DI, DIS, EM, EMD, and SI
safety relays have the power supply connections at the top. The CI safety relay,
which is backward compatible with the MSR127 monitoring safety relay, has
A1 at the top and A2 at the bottom.

Safety Inputs
GSR relays can be connected to the following devices:
• Devices with mechanical contacts
• Devices with OSSD output
• Safety mats
• Safedge™ safety edges
Devices with Mechanical Contacts
The GSR family of safety relays can be connected to safety devices that have
mechanical contacts. The relays can accommodate either 1 N.C. or 2 N.C.
