E-DIO24
Ethernet-Based 24-Channel Digital I/O

MC E DIO24 Ethernet Based 24 Channel Digital I O -

The E-DIO24 provides 24 lines of digital I/O with ±24 mA drive capability

Overview

The E-DIO24 digital I/O device is ideal for network-based applications and remote monitoring and control. The device provides 24 high-drive channels for driving relays, and one counter channel.
The E-DIO24 is functionally equivalent to USB-DIO24 Series and USB-1024 Series devices, making application migration easy.

Features

24 digital I/O lines
±24 mA drive capability
Digital output alarm
One 32-bit event counter (shared with a DIO pin)
Remote network configuration
DIN-rail compatible
Available with enclosure and screw terminals, or board-only OEM with header connectors
External power supply included with standard version

Supported Operating Systems

Windows® 11/10/8/7/Vista® 32/64-bit
Linux®
Android™

Ethernet Interface
The E-DIO24 has a built-in high-speed communication port. Users can remotely access and configure the device with software over the internet.
Digital I/O
The E-DIO24 has 24 digital I/O lines configured as three 8-bit ports. Each bit is individually configurable for input or output.
Users can enable a digital bit configured for output to change state when a host connection is established or broken.
Data can be transferred at rates up to 5 kS/s when the device and host are connected by Ethernet to the same local network.
Typical throughput is system-dependent.
All DIO lines are pulled high by default to 5 V through 47 kΩ resistors through three onboard jumpers. Each jumper configures one 8-bit digital port, and can easily be changed to pull-down.
Counter Input
The 32-bit event counter pin counts TTL pulses, and accepts frequency inputs up to 10 MHz. Users access the counter using the pin shared with digital port 2 bit 7 (P2D7).
External Power
The E-DIO24 requires 5 VDC power to operate. A 5 volt, 1 amp adapter ships with the standard device (MCC p/n PS-5V1AEPS). OEM users can connect a 5 V supply to a 2-pin terminal block header or to the barrel connector on the board.
E-DIO24-OEM
The E-DIO24-OEM has a board-only form factor with header connectors for OEM and embedded applications (no case, CD, or Ethernet cable). The device can be further customized to meet customer needs.

Specifications
These specifications apply to both E-DIO24 standard and OEM version unless noted otherwise.
Digital input/output
Digital type: 5 V TTL input / CMOS output
Number of I/O: 24, configured as 3 ports of 8 bits each (Port 0, Port 1, Port 2) Configuration: Each bit can be independently configured for input or output Pull-up configuration: Each port has 47 kΩ resistors configurable as pull-up (default) or pull-down via internal jumpers.
Digital I/O transfer rate (system paced): 100 to 5000 reads/writes per second, typical, on a local network.
This is the typical throughput when the device and host are both connected by Ethernet to the same local network. Throughput can vary significantly. Typical throughput is not guaranteed if a wireless connection is involved or data is sent over the internet.
Alarm functionality A digital output bit may be configured to change state when an Ethernet connection with a host is established or lost.
Power on and reset state: All input, unless the alarm functionality is enabled.
