ETH0621 - 24v Motor controller and ethernet relay module

Devantech

Overview

The ETH0621 offers 6 digital inputs (accepting 10V - 24V), 2 independently switched 24V 5A outputs and a 24 volt, 5A motor controller that effortlessly integrates motion control over Ethernet. The ETH0621 also includes a motor surge protection circuit that shuts the motor down in the event of the current exceeding 22A.

Operating Temperature

-40C to +85C

LED indication

The ETH0621 provides a blue LED for indication of power to the board, this will pulse quickly in the event of the firmware being updated and for 400ms every 2 seconds in the event that the board has detected a current surge and shut the motor down. There are red LED's mounted next to the digital outputs and relays to indicate there state. Green LED's are mounted next to each of the 6 inputs to indicate active inputs.

Relay power rating

If the contact load voltage and current of the relay are in the region enclosed by the solid and dotted lines in the figure below, the relay can perform stable switching operation. If the relay is used at a voltage or current exceeding this region, the life of the contacts may be significantly shortened.

load type	Typical applications	Rating	Max DC load capacity
AC1	Non inductive or  slightly inductive loads	16A @ 250V AC
AC15	Control of   electromagnetic load   (>72VA)	3A @ 120V AC    1.5A @ 240V AC
AC3	Control of motor	750W
DC1	Non inductive or  slightly inductive loads	16A @ 24V DC
DC13	Control of electromagnetic   loads	0.22A @ 120V DC  0.1A @ 250V DC

Control

The relay board communicates via TCP/IP and is controlled with a set of commands, which are sent to the board's IP-address on a configurable port. The commands are sequences of bytes, for example:
The sequence 0x20, 0x01, 0x32 will turn on relay number 1 for 5 seconds. A full specification can be found at the manufacturer's spec (see link below).

Control via ASCII-commands and also a long requested feature of control via http is possible with all available firmware versions. For example: Sending a http GET to
192.168.0.200/io.cgi?DOI1=10
sets relay 1 on active for 1 second (This would use the default address 192.168.0.200). You can test these functions by typing them directly into the address bar of most internet browsers. Also be aware that you may need to disable http authentication in the http configuration if your control device does not support it. A full specification and firmware updates can be found at the manufacturer's spec (see link 'Technical Specification' below).

Connections

Mapped inputs

Digital inputs of the ETH484, ETH044, ETH8020 or WIFI484 are able to be configured to remotely control outputs on all of Devantech's new ethernet relay boards (both wired and WIFI), the older ETH-RLY02 and ETH-RLY16 are not compatible however. The mapped inputs offer simple linking and versatile usage, an input in one country can control a output in another, or across a small network.
Possible target boards are:

• ETH002
• ETH008
• ETH044
• ETH0621
• ETH484
• ETH8020
• WIFI002
• WIFI008
• WIFI484
• WIFI8020

The independent inputs can be mapped to different relays (on the same or different boards). As address of target board you can enter an IP address or hostname (which will be converted to an IP address by the DNS server supplied in the board configuration). If the module is on the local network then you can use the assigned IP address, if the target is over the internet then you need to supply the gateway in the configuration (internet source IP like your router) and the "Address of target board" is the IP address of the targets internet connection (to point at the router).
