Features & Benefits
Transmit 12 RTD-based temperature measurements and a single contact status
up to 500 meters using inexpensive fiber-optic cable with the SEL-2600 RTD
Module. The SEL-2600 connects directly to the SEL-701 Motor Relay using fiber-
optic connectors built into each device and also connects to the SEL-2030 Commu-
nications Processor using a single SEL-2800 Fiber-Optic Transceiver. The fiber-
optic link eliminates expensive cable pulls and provides electrical noise immunity
and ground isolation.
Measure up to 12 RTD temperatures plus one contact input with
zero settings.
LEDs indicate device status, transmit status, and contact
input status.
Power from 120 Vac or 240 Vac.
Operates in extreme ambient temperatures from – 40º to +85º C .

Ground the SEL-2600 by connecting Terminal 26 to an appropriate electrical ground. Step 5. Connect as many as 12 RTDs to the SEL-2600 terminal blocks (see Figure 5 on page 13). Step 6. Record the type and location of each RTD in Table 1 on page 4. -
Page 4: Sel-701 Motor Relay Application
SEL-701 Motor Relay accurately tracks the heating effects of overloads and unbalance current. Combining the SEL-2600 and the SEL-701 Motor Relay enhances this list of protection features by adding remote RTD-based thermal protection. Fiber-Optic Ports (built into SEL-2600 &... - Page 5 Set the SEL-701 Motor Relay to accept the RTD temperature data packets (see Data Packet Definition on page 11) sent by the SEL-2600. You can use any of the following three methods to enter the settings. Relay front-panel menus: Set Relay\Relay Elements\RTD CONFIGURATION.

(see Table 3 on page 11) into the reserved USER data region at the addresses shown in Table 2 on page 9. The SEL-2600 data packet includes temperature information for each of the four types of RTDs. To access the correct temperature, use the memory map loca- tion associated with the correct RTD type. - Page 9 Line 4: Copies the sign bit (Bit 15) of 034h into Bit 0 of 035h. Line 5: Clears Bit 0 of 35h if RTD is shorted. Line 6: Clears Bit 0 of 35h if RTD is open.

Page 11: Data Packet Definition
Data Packet Definition Data Packet Definition The SEL-2600 RTD Module sends a binary data packet every 0.5 seconds. The packet contains data for all four types of supported RTDs so no settings are required in the SEL-2600 (patent pending). Using the SEL-2800 Fiber-Optic Transceiver, any EIA-232 device can be configured to understand the binary data packet con- tents shown in Table 3. -
