MEX IO EXPANDERS Mex816u

MEX IO EXPANDERS Mex816u

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.

Description

Specification
Brand/ ManufacturerALC
Communication Ports:Xnet I/O Expander bus for 500 Kbps communications between ME controller and I/O Expanders.
Universal Inputs: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 (12.5mSec minimum pulse duration).
Universal Outputs:Universal outputs that are jumper configurable as 0-10V-dc, or 0-20mAdc with 12-bit D/A or 24V-dc @ 50mA relay drive. HOA (hand/off/auto) switches for all outputs, including potentiometer for manual adjust- ment of analog outputs.
Expansion:Five 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. Compatible with legacy Mx I/O expanders using the 9-pin Sub-D connector only.
Status Indicators:LED status indicators for Power, Run, Error, Xnet TX and Xnet Rx.
Addressing:Rotary dip switches for intuitive network addressing of modules.
Protection: Built-in surge and transient protection circuitry for power, communications and I/O.
Listed By:UL916 (Canadian Std C22.2 No. 205-M1983), CE, FCC Part 15 – Subpart B – Class A.
Environmental Operating Range:-20oF to 140oF (-29oC to 60oC); 10 to 90% relative humidity, non-condensing.
Power Requirements:24 V-ac ± 10%, 50-60Hz, 45VA, or 26 V-dc ± 10%, 21W. NOTE: Power consumption will increase when BACview6 or other accessories are attached.
