CAN-in-/output modules with 8 in- and 8 outputs (relay 1A)

More info

CAN-Interface

Transfer rate

The CAN-bus may have a length of up to 10 km! The selectable transfer rates are 1 Mbit/s, 500 Kbit/s, 250 Kbit/s, 125 Kbit/s, 100 Kbit/s, 50 Kbit/s, 20 Kbit/s or 10 Kbit/s. The transfer rate is configurable by software or by DIP-switches.

CAN-Interface connection (galvanically isolated)

The CAN-interface connection is realized by a 9 pin D-SUB socket connector. The galvanically isolated CAN interface ensures a protection against connected CAN devices by using optocouplers.

CAN-Addressing

The CAN-interface is configurable in three different ways.

Special mode

The usage of this mode is to set the CAN-interface quickly to default values. This is helpfull for a quick and easy setup and facilitates an error analysis or an initial operation.

Software mode

The software mode is to fully setup the module using an included software. It is possible to set up:

• Transfer rate
• CAN 2.0A (11 bit-addressing, "base frame format") oder CAN 2.0B (29 bit-addressing, "extended frame format ")
• CAN-interface address
• Response-Modul-Address (responses are sent to this address)

DIP-switch mode

The DIP-switch mode is to manually configure the CAN-interface using DIP-switches. The DIP-switch configuration may be read out using the DELIB-Configuration Utility. A configuration-check is therefore easy and simple.

Inputs

Visual monitoring of inputs

The state of every input is directly indicated by a LED. That way, wrong wiring is easily noticeable.

Detecting short input pulses

The module won't miss fast state changes, even if the inputs are sampled in larger periods. Fast state changes between two readout-cycles are detected through an additional logic and can be readout by software. A LED (combined for all inputs) indicates a "state change". The LED does not extinguish until the software register for input state changes is read out.

Counter

Every input channel has a 16 bit counter. The maximum counting speed is 10kHz. Herewith the module "counts" additional events.

Input protection using optocoupler

The inputs have AC-suitable optocouplers. Therefore you don't need to pay attention to the polarity while wiring the inputs.

Input voltage

By default the inputs are designed for a voltage of 24V. They can be adjusted (even later) to 15V, 12V or 5V.

Relay Outputs

Relay-outputs (galvanically isolated, permanent load of 1A AC)

Relays ensure a save galvanic isolation of the outputs. They are designed for up to 36V/1A. Maximum switchable power is 20W.

Timeout-protection

If required, a timeout-protection may be enabled, switching automatically off the outputs to prevent damage. This takes place, when e.g. the communication gets lost. Switching off the outputs is indicated by a LED.

Time function for digital outputs

The time function allows the hardware to control outputs.
If the outputs regardless of the software for a certain time on or off, so our O8-R8 Module is ideal, because this function is controlles directly from our module.
Is a set time, then it needs no further attention, because the outputs switch reliably after the time.

Connector

Easy to maintain connector system

The plug and socket consist of a multipoint socket connector and a multipin connector with a throw-off lever. Plug-in and plug-out is easy as well as rewiring the terminal strip. The wire connection itself is realized with a screwless connector system. A tool is included with each module.

Config

CAN-Addressing

The CAN-interface is configurable in three different ways. These are the Special-mode, the Softwaremode and the DIP switch mode.

Special mode

The usage of this mode is, to set the CAN-interface quickly and easily to default values. This is helpful for a quick and easy setup and facilitates an error analysis or an initial operation.

Software mode

The software mode is to fully setup the module, using an included software. It is possible to set up:

• Transfer rate

• CAN-interface address
• Response-Modul-Address (responses are sent to this address)

With this software, it is not only possible to store or load the stored configuration values, but also to see the actual set up values of the module. An error analysis is thus greatly facilitated.

DIP-switch mode

The DIP-switch mode is to manually configure the CAN-interface by using DIP-switches. The DIP-switch configuration may be read out, using the DELIB-Configuration Utility. A configuration-check is therefore easy and simple.

Software

Controlling of the CAN modules

Accessing to the RO-CAN modules over the CAN- interface happens by the following ways.

Automatic Sending Mode

The modules are able to send CAN packets automatically in a definded time interval. The time interval can reach from millisecond to second. The following picture shows a packet, which will be sent to the CAN-address 1234.

Automatic Receiving Mode

An automatic receiving on four different CAN-addresses can be configured individually. Also you can define, if the received CAN datas should be given out to relays or D/A converters. The following picture shows a packet, whose datas are sent to the CAN address 543.

A timeout protection switches the relays or D/A outputs, in failure, automatically of.

Also the user can activate a timeout protection. If the RO-CAN module cannot receive any CAN packets after a defined time interval, the module disables all outputs and set the D/A outputs to 0V.

DEDITEC CAN Addressingmode

A special CAN protocol, which have been developed by us, allows registry control to all functions of our modules. So are BYTE-, WORD- and LONG- accesses possible. A registry- and protocol description can be found in our download area.

Configuration by a graphic Windows configuration software

All CAN-addresses, CAN-speed and packet options can be set up from the user, over a special Configuration Utility for the RO-CAN serie. The configuration works over a free serial interface of a PC. Predefined CAN-addresses and several modes are adjustable by DIP switches.

Software-updates and start-up of the RO-CAN modules

Further to the delivered Windows driver library, the RO-CAN modules can be tested and updated with newer firmware. Over graphical testprograms, the modules can be tested and configured (without using the CAN-interface). So you can do test measurements and check the electrical wirings. Are all settings configured, the module can be connected to the CAN-interface.

Connector

Plug connection

Screwless plug connectors

All input and output connectors have a practical, screwless terminal block. An mechanic ejection guarantees a very quick module change without any special tools. Wire connection happens with screwdriver or an included plastic pin. (s. pic.1)

Connection example of a RO-Module

		RO-MODULE
		Step 1: Push the plastic tool into the small notch at the side of the terminal block, to open the clamp contacts for the wire connection.
		Step 2: When you are looking into the wire hole, you can see, that the clamp contacts have been opened. The end of the wire should be bared 5-7mm. Now put it as deep as possible into the opened hole.
		Step 3: After that, pull the plastic tool out of the notch. The clamp is closed again now.
		Step 4: After correct connecting, pull out the wiring by hand isn't no more possible
