1.1 Description of the Module Fig. 1: Block circuit diagram of the CAN-CBX-REL4 module The CAN-CBX-REL4 module offers four monostable relay outputs. Two of these are normally open contacts and two are change over contacts. The individual channels are electrically isolated and therefore various voltages can be applied to the CAN-CBX-REL4 module simultaneously.

5.1.1 General Rules Note: esd grants the EU Conformity of the product, if the CAN wiring is carried out with at least single shielded single twisted pair cables that match the requirements of ISO 118982-2. Single shielded double twisted pair cable wiring as described in chapter 5.2 ensures the EU Conformity as well.
If the used CAN interface is not equipped with an integrated CAN termination and it is at an end of the bus, use external termination plugs. 9-pin DSUB-termination connectors with male and female contacts and earth terminal are available as accessories CAN-CBX-REL4 Page 31 of 99 Manual • Doc.-No.: C.3012.21 / Rev. 1.1...
Select a working combination of bit rate and cable length. Keep away cables from disturbing sources. If this cannot be avoided, double shielded wires are recommended. Fig. 14: CAN wiring for heavy industrial environment Page 32 of 99 Manual • Doc.-No.: C.3012.21 / Rev. 1.1 CAN-CBX-REL4...
DSUB9-connector from ERNI (ERBIC CAN BUS MAX, order no.:154039). The usage of esd’s T-connector type C.1311.03 is not recommended for single shielded double twisted pair cables because the shield potential of the conductive DSUB housing is not looped through this T-connector type.
Optical couplers are delaying the CAN signals. By using fast digital isolators and testing each board at 1 Mbit/s, esd modules typically reach a wire length of 37 m at 1 Mbit/s within a closed net without impedance disturbances like e.g. longer stub.

Via the objects 1600 to 1603 the four relays of the CAN-CBX-REL4 can be switched by mapping of bit-objects with one PDO. In the example below, the relays are switched with the bits 4 - 7 of the first data byte of the RPDO.
With the objects from 1600 to 1603 the four relays of the CAN-CBX-REL4 can be independently switched by individual PDOs. In the example below the relays are switched by bit 0 of the first data byte of the corresponding RPDOs.
