Input Power Connections

The SIMPRO-100 Relay power supply has a
broad operating range that can accept ac or dc
inputs.
Power Supply Operating Range:
• 95 – 240 ± 10% Vac 50/60 Hz
• 20 – 250 ± 20% Vdc
• < 15 VA, typical
The relay power supply is fused internally. If the
fuse operates, make sure that the cause of the
fuse operation has been isolated and corrected
before replacing the fuse and returning the relay
to service. See Section 10: Maintenance &
Troubleshooting for instructions on how to
replace the power supply fuse.
Replacement Power Supply Fuse Ratings:
• T 2 A/250 V, high breaking capacity
2.4.2 Relay Chassis Ground
Connection
Terminals D01 and D10 are the chassis ground
terminals. At least one of these terminals must be
solidly connected to the cabinet ground bus for
correct relay operation and personal safety.
