Description

The compact CAN repeater CRep S26 transmits and amplifies signals transparent to the CAN protocol. Each of the 26 CAN connections has the physical behaviour of a single bus node. CRep S26 permits a flexible design of the network topology and offers special support for star structured networks. Furthermore tree structures and long stub lines are supported. Through the possibility to use the network structure that fits the application best a reduction of installation costs can be reached. The maximum data rate in CAN networks, depending on signal propagation delays, can be increased, if CRep S26 is used to improve the network structure. An increase of the maximum node count in a CAN network can be reached by splitting the network in subnets that are connected by CRep S26. Each subnet makes the number of CAN nodes possible permitted by the drivers output current. Where CAN signals have to be transmitted over long distances, CRep S26 can be used for signal conditioning. The capability to detach erroneous segments from the rest of the CAN system reduces the impact on the intact bus segments for the most commonly occuring errors. The presence of power is indicated by a LED. Furthermore each CAN channel is provided with a LED indicating that this channel has originated a CAN message when the LED is on.

Technical Data

Layout and Connection

A CRep S26 device includes 26 CAN segments with male SUB­D9 connectors.

Pin Name Function
2 CAN_L CAN low bus line
3 GND Ground
7 CAN_H CAN high bus line
1,4,5,6,8,9 NC Not connected

The power supply of CRep S26 is galvanically separated from the CAN system and wired by a terminal block with 2 clamps. The following table shows the terminal assignment of the power connector:

Pin Name Function
1 Power + Positive supply +24V
2 Power – Ground of power supply

The power supply is galvanicly decoupled from the CAN system.

Limiting Values

Parameter Minimum Maximum Unit
Storage temperature -40 +80 °C
Operating temperature 0 +60 °C
Power supply voltage -100 +35 V
Voltage on signal lines -30 +30 V
Maximum power dissipation (at 60°C) n.s. tbd mW

Any (also temporary) stress in excess of the limiting values may cause permanent damage on CRep S26 and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.

Nominal Values

Parameter Minimal Typical Maximal Unit
Current consumption (running idle) n.s. 100 n.s. mA
Current consumption (250 kBits/s, 100% busload) n.s. 280 n.s. mA
Supply voltage 19 24 30 V
Propagation delay between two arbitrary channels n.s. 140 180 ns

All values, unless otherwise specified, refer to a supply voltage of 24V and an environmental temperature of 20°C.
