Introduction
RU-87Pn (n: means 1/2/4/8 slots) series 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 30 I/O modules supported with the unit, including analog
input/output, digital input/output, and counter/frequency I/O modules. RU-87Pn is the best
choice for ISaGRAF PACs connecting to I-87K Remote I/O modules.
Visit to the website for new products about I-87K (High Profile) remote I/O modules.
RU-87Pn is designed to be used in harsh and noisy environment, so the hardware is
manufactured with wide power input range (10 ~ 30 V
DC
) and operating temperature (-25 ~ +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 DLL, ActiveX, Labview
driver, Indusoft driver, Linux driver, OPC Server, etc. The ISaGRAF PACs can connect to the
RU-87Pn directly. The I-87K series I/O modules plugged in the RU-87Pn can be easily integrated
into variant software system.
