Rơ le trung gian OMRON G7T

Công ty TNHH Ngân Anh Phát chuyên cung cấp dòng sản phẩm Rơ le trung gian OMRON G7T chính hãng xuất xứ Japan tại thị trường Việt Nam.

Đặc điểm nổi bật của Rơ le trung gian OMRON G7T

• Có các dạng tiếp điểm SPST-NO, SPST-NC và SPDT cho đầu ra (chỉ SPST-NO cho đầu vào).

• Vỏ ngoài siêu mỏng với kích thước 29 (R) x 10 (S) x 32 (C) mm.

• Tất cả các rơ le đầu ra cung cấp độ bền lâu dài (1.000.000 lần hoạt động ở 5 A), trong khi tất cả các rơ le đầu vào cung cấp công suất chuyển mạch vi mô (100 μA ở 1 V).

• Được chứng nhận bởi các tiêu chuẩn UL và CSA.

Note: 1. The rated current and coil resistance values are measured at a coil temperature of 23°C. Tolerances of AC rated
              current are +15%, –20% and tolerances of coil resistance are ±15%.
           2. Four rated voltages or currents are available to single AC models used with the P7TF-05 Socket. Only three
                rated voltages or currents are available, however, when the Relay is used in place of the G7TC.
           3. The operating characteristics values are for a coil temperature of 23°C.
           4. The maximum voltage is one that is applicable to the Relay coil instantaneously at 23°C and not continuously.

Note: 1. The above values are all initial values.
           2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
           3. The operate and the release times were measured with the rated voltage imposed with any contact bounce
                 ignored at an ambient temperature of 23°C.
           4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used
                 for checking the dielectric strength.
           5. The electrical endurance was measured at an ambient temperature of 23°C.
           6. This value was measured at a switching frequency of 120 operations per minute.
