1. Introduction
ET-87P2/4/8 series is a remote intelligent I/O expansion unit to expand I-87K series
I/O modules over the Ethernet for industrial monitoring and controlling applications. It
offers two Ethernet switch ports to form a daisy-chain topology. The daisy-chain
feature allows ET-87P2/4/8 to connect in series to each other or other Ethernet
devices. Users can easily simplify the cabling and save installation space with the
feature.
ET-87P2/4/8 is designed to be used in harsh and noisy environment, so the hardware
is manufactured with wide power input range (10~30 V
DC
), isolated power input and
can operate under wide temperature (-25 °C ~ +75 °C). To simplify installation and
maintenance of I/O modules, it provides many useful features, such as: hot swap
allowed, auto configuration, LED indicators for fault detection, dual watchdog to keep
alive, programmable power on and safe values for safety.
There are more than 30 I/O modules supported with the unit, including analog
input/output, digital input/output, counter, frequency I/O modules. We provide various
software development kits (SDK) and demos, such as DLL, ActiveX, Labview driver,
InduSoft driver, Linux driver, OPC server, etc. The I-87K series I/O modules plugged
in the ET-87P2/4/8 can be easily integrated into variant software system.
