ME812u Controller Series

ME812u Controller Series

Superior Performance and Reliability

The MEx series of I/O expanders is designed for the powerful ME series of controllers, and for the most demanding control applications in the industry. The MEx I/O expanders can be remote mounted or directly mounted on the ME controllers.

All Models have
Rnet port for Rnet communicating devices such as ZS room sensors and Touch interfaces. 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
