The semiconductor switch has a relatively long service life and no oscillations are generated during the switching process, making it suitable for applications with frequent switching actions.<\/p>\n\n\n\n<p>The standard version of the BMR-P series supports 2-channel outputs covering the output range of 3\u03a9-1M\u03a9, with a step resolution of approximately 0.13\u03a9 and a power rating of up to 0.5W (max. voltage 60V). In terms of accuracy, the series overcomes the disadvantage of large on-resistance of optocouplers, and the initial accuracy of Class B can easily reach \u00b1(0.04%+0.1\u03a9) in the full output range.<\/p>\n\n\n\n<p>BMR-P series supports 6~24V wide voltage power supply, and optional rich communication interfaces (isolated RS485, RS232 and CAN), of which RS485 supports maximum 256 nodes networking.<\/p>\n\n\n\n<p>In addition, the module housing is designed to fit the industrial application scenarios and supports standard DIN rail mounting.<\/p>\n\n\n\n<p><a rel=\"noreferrer noopener\" href=\"http:\/\/www.eastwood.tech\/wp-content\/uploads\/2025\/02\/BMR-P\u9694\u79bb\u5feb\u5207\u578b\u7a0b\u63a7\u7535\u963b\u6a21\u5757\u8bf4\u660e\u4e66_v0.3.pdf\" target=\"_blank\">Specification&amp;manual-CN-v0.32<\/a><\/p>\n\n\n\n<p><a href=\"http:\/\/www.eastwood.tech\/wp-content\/uploads\/2025\/11\/BMR-P-Series-Isolated-Fast-Switching-Programmable-Resistor-Module-SpecManual-v0.31.pdf\">Specification&amp;manual-EN-v0.31<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>BMR-P series programmable resistor modules use optocouplers as switching switches for the resistor network, isolating the drive circuit from the output resistor, featuring a typical switching speed of 1ms.
