SEL-2600 RTD Module
RTD Connections at the SEL-2600 RTD Module
The SEL-701 Relay is compatible with the SEL-2600 RTD Module that monitors
up to 12 RTD inputs and a single contact input. The module uses a fiber-optic cable to
communicate temperature measurements and the contact status back to the relay.
You may connect any of the four supported RTD types to any of the 12 available
RTD inputs. The SEL-2600 RTD Module has the same RTD input requirements as the
SEL-701 Relay, described in Internal RTD Connections (Relay Models 0701010X &
0701011X) on page 2.18. The module does not require settings.
You can locate the module up to 1600 feet (500 meters) from the relay, near the
protected motor.
Fiber-Optic Connection to SEL-2600 RTD Module
Connect the SEL-2600 RTD Module Fiber-Optic TX port to the SEL-701 Relay
Fiber-Optic RX port using an SEL Fiber-Optic Cable C801FD. The maximum cable
length allowed is 1600 feet (500 meters).
