• Operating temperature: -25°C to +70°C (-13°F to +158°F)
• Tandem input/output circuitry (906 models only) connects input buffers with open-source outputs for convenient loopback monitoring of the output state
• Watchdog timers provide a configurable failsafe output state for use when host I/O communication is lost
• Three-way isolation eliminates potential ground loops between power, I/O, and network circuitry
• Self-diagnostics monitor microcontroller activity to detect operational failures (lock-up) and execute a reset to restore communication
• Standard Modbus RTU protocol with high-speed RS-485 communication (up to 115K bps)
• Twelve I/O channels in a single inch-wide unit reduces system costs and saves panel space
• High-voltage, high-current, open-source outputs enable direct (high-side) control of external devices
• High-voltage buffered inputs monitor discrete levels from a variety of industrial devices
