CHAPTER 2: PRODUCT DESCRIPTION ORDER CODESD30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 2-1322.3.3 Replacement modulesReplacement modules can be ordered separately. When ordering a replacement CPU module or faceplate, provide theserial number of your existing unit.Not all replacement modules apply to the D30 relay. The modules specified in the order codes for the D30 are available asreplacement modules for the D30.The order codes shown here are subject to change without notice. See the ordering page athttp://www.gedigitalenergy.com/multilin/order.htm for the latest options.Table 2-8: UR order codes for replacement modules, horizontal units7L Channel 1 - RS422; Channel 2 - 820 nm, multimode, LED7M Channel 1 - RS422; Channel 2 - 1300 nm, multimode, LED7N Channel 1 - RS422; Channel 2 - 1300 nm, single-mode, ELED7P Channel 1 - RS422; Channel 2 - 1300 nm, single-mode, Laser7Q Channel 1 - G.703; Channel 2 - 1300 nm, single-mode Laser7R G.703, 1 Channel7S G.703, 2 Channels7T RS422, 1 Channel7W RS422, 2 ChannelsUR - ** - *POWER SUPPLY (redundant supply onlyavailable in horizontal units and must besame type as main supply) (for redundantsupply, must swap both power supplies whenswitching from RH to SH)| SH A | 125 / 300 V AC/DC| RL H | 24 to 48 V (DC only)CPU | T | RS485 with 3 100Base-FX Ethernet, multimode, SFP with LC| U | RS485 with 1 100Base-TX Ethernet, SFP RJ-45 + 2 100Base-FX Ethernet, multimode, SFP with LC| V | RS485 with 3 100Base-TX Ethernet, SFP with RJ-45FACEPLATE/DISPLAY | 3C | Horizontal faceplate with keypad and English display| 3D | Horizontal faceplate with keypad and French display| 3R | Horizontal faceplate with keypad and Russian display| 3A | Horizontal faceplate with keypad and Chinese display| 3P | Horizontal faceplate with keypad, user-programmable pushbuttons, and English display| 3G | Horizontal faceplate with keypad, user-programmable pushbuttons, and French display| 3S | Horizontal faceplate with keypad, user-programmable pushbuttons, and Russian display| 3B | Horizontal faceplate with keypad, user-programmable pushbuttons, and Chinese display| 3K | Enhanced front panel with English display| 3M | Enhanced front panel with French display| 3Q | Enhanced front panel with Russian display| 3U | Enhanced front panel with Chinese display| 3L | Enhanced front panel with English display and user-programmable pushbuttons| 3N | Enhanced front panel with French display and user-programmable pushbuttons| 3T | Enhanced front panel with Russian display and user-programmable pushbuttons| 3V | Enhanced front panel with Chinese display and user-programmable pushbuttons| 3I | Enhanced front panel with German display| 3J | Enhanced front panel with German display and user-programmable pushbuttonsCONTACT INPUTS AND OUTPUTS | 4A | 4 Solid-State (no monitoring) MOSFET outputs| 4B | 4 Solid-State (voltage with optional current) MOSFET outputs| 4C | 4 Solid-State (current with optional voltage) MOSFET outputs| 4D | 16 Contact inputs with Auto-Burnishing| 4L | 14 Form-A (no monitoring) Latching outputs| 67 | 8 Form-A (no monitoring) outputs| 6A | 2 Form-A (voltage with optional current) and 2 Form-C outputs, 8 contact inputs| 6B | 2 Form-A (voltage with optional current) and 4 Form-C outputs, 4 contact inputs| 6C | 8 Form-C outputs| 6D | 16 Contact inputs| 6E | 4 Form-C outputs, 8 contact inputs| 6F | 8 Fast Form-C outputs| 6G | 4 Form-A (voltage with optional current) outputs, 8 contact inputs| 6H | 6 Form-A (voltage with optional current) outputs, 4 contact inputs| 6K | 4 Form-C and 4 Fast Form-C outputs| 6L | 2 Form-A (current with optional voltage) and 2 Form-C outputs, 8 contact inputs| 6M | 2 Form-A (current with optional voltage) and 4 Form-C outputs, 4 contact inputs| 6N | 4 Form-A (current with optional voltage) outputs, 8 contact inputs| 6P | 6 Form-A (current with optional voltage) outputs, 4 contact inputs| 6R | 2 Form-A (no monitoring) and 2 Form-C outputs, 8 contact inputs| 6S | 2 Form-A (no monitoring) and 4 Form-C outputs, 4 contact inputs| 6T | 4 Form-A (no monitoring) outputs, 8 contact inputs| 6U | 6 Form-A (no monitoring) outputs, 4 contact inputs| 6V | 2 Form-A outputs, 1 Form-C output, 2 Form-A (no monitoring) latching outputs, 8 contact inputsCT/VT MODULES(not available for the C30)| 8L | Standard 4CT/4VT with enhanced diagnostics| 8N | Standard 8CT with enhanced diagnostics| 8M | Sensitive Ground 4CT/4VT with enhanced diagnostics| 8R | Sensitive Ground 8CT with enhanced diagnosticsINTER-RELAY COMMUNICATIONS | 2A | C37.94SM, 1300 nm single-mode, ELED, 1 channel single-mode| 2B | C37.94SM, 1300 nm single-mode, ELED, 2 channel single-mode| 2E | Bi-phase, single channel| 2F | Bi-phase, dual channel| 2G | IEEE C37.94, 820 nm, 128 kbps, multimode, LED, 1 Channel| 2H | IEEE C37.94, 820 nm, 128 kbps, multimode, LED, 2 Channels| 2I | Channel 1 - IEEE C37.94, multimode, 64/128 kbps; Channel 2 - 1300 nm, single-mode, Laser| 2J | Channel 1 - IEEE C37.94, multimode, 64/128 kbps; Channel 2 - 1550 nm, single-mode, LaserD30 - * ** - * * * - F ** - H ** - M ** - P/R ** Reduced Size Vertical Mount (see note regarding P/R slot below)
