2-channel CAN Bus repeater. Non-isolated. Transmits and amplifies CAN signals transparent to CAN protocol, with low propagation delay, and shutdown of erroneous bus segments. Allows the design of flexible wiring topologies. Rail-mountable.

SKU: WU-12-01-0xx-20 Categories: ,

The CRep N 2-channel CAN Bus repeater transmits and amplifies CAN signals transparent to the CAN protocol. CRep N allows the design of flexible wiring topologies, with star and tree structures and stub lines easily realized.

Key Features

  • Protocol transparent 2-channel CAN repeater
  • Low propagation delay
  • Shutdown of erroneous bus segments
  • Choice of Baud Rate: 10/20/50/125/250/500kBaud (selected at order time via factory set inhibit time)
  • Rail Mountable
  • FCC Class A Verified (use restricted to commercial, business, and industrial environments)
  • Backed by 25+ years CAN expertise

Baud Rate Settings & Overall Cable Length Restrictions

CRepN repeaters are available in a number of baud rate configurations. The maximum CAN cable length, which is the distance between the furthest two nodes in the network, is related to the operating baud rate as follows:

Baud RateMaximum Cable Length with single CRep N added

When a CRep N repeater is used, the effect of the propagation delay through the repeater must be included in the cable length calculation.

For a CRep N repeater, the typical and maximum propagation delays is 100ns and 175ns, respectively. Assuming a 5.5ns/m propagation delay for cable, the maximum propagation delay through the CRep N repeater is equivalent to a cable length of roughly 32m (rounding-up).

500kbit/s100 – 32 = 68m
250kbit/s250 – 32 = 218m
125kbit/s500 – 32 = 468m
50kbit/s1000 – 32 = 968m

Layout and Connection

CRep N devices include 2 CAN segments, wired by a terminal block with 8 clamps. Besides the CAN signals the terminal block also carries the power supply for CRep N. The following table shows the terminal assignment.
