RU-87Pn 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 designed to be used in harsh and noisy environment, so the hardware is
manufactured with wide power input range (10~30 V
~ +75℃). 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 I-87K series I/O
modules plugged in the RU-87Pn can be easily integrated into variant software system.

Features
Hot Swap
The RU-87Pn doesn't need to shut down its power to replace or plug I-87K I/O modules.
Therefore, the whole system can keep operating without any interruption.
Auto-Configuration
Configurations of I-87K I/O modules can be pre configured and stored in the nonvolatile
memory of the RU-87Pn. When the RU-87Pn is power on or an I-87K I/O module is
plug in, the RU-87Pn automatically check and restore these configurations to each
I-87K I/O modules on it.
Easy Duplicate System
Using the DCON Utility, you can easily make a backup of the I-87K module
configurations and write to another RU-87Pn. This design can easily and quickly
duplicate many RU-87Pn
