Additional Information
Installation & Configuration
The Honeywell 2108B2001N digital input module is designed for easy installation in ControlEdge PLC systems. The module mounts on standard 35mm DIN rail or can be panel-mounted using the provided hardware. Wiring should be performed using shielded cables for best noise immunity, with the shield connected to the dedicated ground terminal.
Configuration is performed using Honeywell's ControlEdge Studio software, which allows for setting input filter times, enabling open wire detection, and configuring diagnostic parameters. The module supports auto-addressing via the backplane, eliminating the need for manual DIP switch settings. Firmware updates can be performed remotely through the ControlEdge Studio software.
For optimal performance, the module should be mounted in a clean, dry environment within the specified temperature and humidity ranges. Adequate ventilation should be provided to ensure proper heat dissipation. Regular maintenance includes periodic inspection of connections and cleaning of the module housing to prevent dust accumulation.
