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
connecting to I-87K Remote I/O (only support High Profile) 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
℃
). 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.
