When ordering, add the rated coil voltage to the model number. Example: G2R-1A 12 VDC Rated coil voltage 2. OMRON has also prepared the above relays with AgSnIn contacts, which are more tolerant of large inrush currents and physical movement compared with relays with standard contacts. When ordering, add "-ASI" to the model number. Example: G2R-1A-ASI 3. Standard, NO contact type relays are TV-3 class products in accordance with the TV standards of the UL/CSA. Models with AgSnIn contacts are TV-5 class products. Example: G2R-1A-ASI When ordering a TV-8 class model, insert "-TV8" into the model number as follows: Example: G2R-1A-E-ASI-TV8 4. BEAB approval relates to High Capacity type only.

The above minimum mounting space is necessary due to mutual thermal interference generated by the relays. This restriction may be ignored, however, depending on the operating conditions of the relays. Consult OMRON for details. There is no restriction on the mounting direction of each relay on the PCB. When using this circuit, confirm the set and reset states and then take into account the circuit constant. 1 15 (2.1)
