ET-87Pn series is an Ethernet compatible remote intelligent I/O expansion desinged to house and power the range of I-87K series I/O modules. The unit provides two Ethernet switch ports which can form a daisy-chain topology. This feature permits the ET-87Pn to connect in series with other similar devices or other Ethernet devices. Thus simplify the cabling and saving installation cost.
ET-87Pn is designed to be used in harsh and noisy environments. \The hardware operated within a wide power input range (10 ~ 30 VDC), and can operate under a wide temperature range (-25 °C ~ +75 °C).
To simplify installation and maintenance of I/O modules, it provides many useful features, such as: Hot swapability, auto configuration, LED indicators for fault detection, dual watchdog, programmable power on and fail safe values on power failiure are features incorporated to increase reliability and simplify installation and maintenance.
The unit supports more than 30 I/O modules including analog input/output, digital input/output, counter, frequency I/O modules.
