• RS-485 Port for Multi-Drop Topology
• DCON Protocol
• 9 I/O Slots for I-87K Modules
• Operating Temperature: -25 ~ +75 °C


I-87K9 is an I/O expansion unit to expand I/O via the RS-485. It is designed to be used in harsh and noisy environment, so the hardware is manufactured with wide power input range (10 ~ 30 VDC), isolated power input and can operate under wide temperature (-25 ~ +75 °C). To simplify installation and maintenance of I/O modules. 

​​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. The I-87K series I/O modules plugged in the I-87Kn can be easily integrated into variant software system.
