This remote I/O terminal provides distributed control capabilities for MICREX-SX SPH systems. It connects field devices to the main controller through OPCN-1 network interfaces. System engineers deploy this module for efficient data acquisition across large manufacturing facilities. Its distributed architecture reduces wiring costs and simplifies system expansion significantly.
I/O Architecture and Field Connectivity
The Fuji NR1JW-16T65DT offers 16 discrete input points for sensor and switch connections. Its output channels provide 0.5 A per point for controlling relays and solenoids. Each input channel accepts 24 VDC signals from standard industrial field devices. The module delivers reliable performance with response times of 3 ms or less. Furthermore, photocoupler isolation protects the control system from electrical noise and transients.
Network Communication and Protocol Support
This module supports OPCN-1 network communication with a transmission speed of 250 Kbps to 1 Mbps. The network distance reaches up to 800 meters depending on the selected baud rate. The module occupies 1 word of memory for every 16 I/O points in the system. Users can connect up to 31 stations in a multi-drop bus topology. Consequently, this module enables flexible system configurations across extensive plant areas.
Mechanical Design and Physical Specifications
The Fuji NR1JW-16T65DT measures 148 mm in width, 50 mm in height, and 40 mm in depth. Its compact size facilitates design standardization across multiple control panels. The unit features a safe terminal block that prevents screw loss during wiring operations. Moreover, the modular design allows network modifications through simple unit replacement without panel redesign.
