The G3VM-401G1(TR) is a miniature, panel-mount photocoupler manufactured by Omron. It is a single-channel photocoupler which can be used for TDM (Time-Division Multiplexing) and PLC (Programable Logic Controller) signal isolation. The G3VM-401G1(TR) features high ambient temperature operation and excellent CTR value (Current Transfer Ratio), making it ideal for use in harsh environments where other isolators cannot guarantee an acceptable level of reliability. The G3VM-401G1(TR) has a high load capability and can safely transfer signals even when the load current is as high as 50mA. It has a wide control range, allowing it to be used in various applications. Additionally, it is also very compact in size, making it easy to install in any system.
