Xnet (500 Kbps) port for MEx I/O expansion modules. Local access port. |
| Universal Inputs: | Twelve configurable universal inputs with 14-bit A/D resolution. Supported input types include: 0-5 V-dc, 0-10 V-dc, 0-20 mA, Thermistor (10k Ohm Type II), 1k Ohm RTD (Platinum, Nickel or Balco), and Dry Contact. All inputs support pulse counting up to 40 cycles per second (25mSec minimum pulse). |
| Universal Outputs: | Eight universal outputs are jumper configurable as 0-10V-dc, or 0-20mAdc with 12-bit A/D or 24V-dc @ 50mA relay drive. HOA (hand/off/auto) switches for all outputs, including potentiometer for manual adjustment of analog outputs |
| Expansion: | Six MEx I/O expansion modules can be connected – one mounted directly on top of the controller, mounted locally in a stack configuration or remote-mounted up to 100ft away. |
| Microprocessor: | Powerful 32-bit Motorola Power PC microprocessor. High-performance 32-bit communication co-processor. I/O expansion CAN co-processor |
| Memory: | 32-bit memory bus structure, 8 Mbyte flash memory, 16 Mbyte SDRAM battery-backed. Battery CR123A has life of 10 years with 720 hours of cumulative power outage |
| Real-time Clock: | Battery-backed real-time clock |
| Status Indicator: | LED status indicators for EIA-232/485 communication, and low battery status. Seven-segment status display for running, error, and power status |
| Module Addressing: | Rotary dip switches for intuitive network addressing of modules. |
| Protection: | Built-in surge and transient protection circuitry for power, communications and I/O |
