Specs & cross references: 12 VDC coil, SPDT (1 Form C) contacts, 16 A resistive rating, max switching 380 VAC / 125 VDC, coil resistance ≈275 Ω (≈43.6 mA), operate/release 15 ms / 5 ms, dielectric 5 kV (coil-to-contacts), surge 10 kV, operating temp −40 to 70 °C, size 29 × 13 × 25.5 mm. Compatible with Omron G2R-1-E DC12 aliases such as G2R-1E-DC12 / G2R1EDC12 part codes.
Install & location: PCB through-hole mounting; SPDT pin layout for G2R-1-E footprint. Typical board locations: fan/blower output, compressor/contactor drive, pump/motor interposing relay, heater/aux output. Observe creepage/clearance, use a diode or TVS across the coil for DC drive, and an RC snubber or MOV on inductive loads. Note: socket bases like P2RF-xx are for G2R-1-S plug-in versions; this -E model does not fit sockets.
Application compatibility (equipment categories): Compatible with control boards that specify “G2R-1-E DC12” for the relay position—HVAC air handlers/furnaces/boilers/condensing units, dehumidifiers, vending/coffee machines, refrigeration, PLC I/O panels, CNC/3D-printer controllers, alarm/automation panels, lab and test gear. Use as a fan relay / heat relay / cool relay / pump relay / general interposer where an SPDT 16 A PCB relay is required.
Fixes common faults: Designed to replace failed on-board SPDT relays causing no-start fans or pumps, compressor not engaging, intermittent outputs, audible chattering/clicking, welded NO/NC contacts, or overheated relay pads. Match coil voltage, footprint and contact rating before installation; reflow with proper solder technique to avoid pad lift on aged boards.
Complementary parts for a complete repair: Pair with a flyback diode on the coil (e.g., 1N400x class) and an RC snubber/MOV on inductive loads to extend relay life. If your system uses a socket-mount relay, select a Compatible with Omron G2R-1-S plug-in versionand the matching Compatible with Omron P2RF socket instead; the PCB G2R-1-E is for direct soldering; the PCB G2R-1-E is for direct soldering. Add fuses/terminal blocks as required by your panel design.
وصف
