RU-87P8 is a remote intelligent I/O expansion unit that used to expand I-87K series I/O modules over the RS-485 for industrial monitoring and controlling applications. There are more than 50 I/O modules supported with the unit, including analog input/output, digital input/output, and counter/frequency I/O modules.

RU-87P8 is designed to be used in harsh and noisy environment, so the hardware is manufactured with wide power input range (10 ~ 30 VDC) and operating temperature (-25 °C ~ +75 °C). It simplifies installation and maintenance of I/O modules with hot swappable and auto configuration, fault and error detection, dual watchdog, programmable power on and Safe Values.

Various software development kits (SDK) and demos are provided, such as PACSDK, LabVIEW driver, InduSoft driver, Linux driver, OPC Server, etc. The I-87K series I/O modules plugged in the RU-87Pn can be easily integrated into variant software system.
