The CRep S4 4-channel CAN Bus repeater transmits and amplifies CAN signals transparent to the CAN protocol. The CRep S4 allows the design of flexible wiring topologies, with star and tree structures and stub lines easily realized.

Key Features

  • Protocol transparent 4-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

CRep S4 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 S4 added

When a CRep S4 repeater is used, the effect of the propagation delay through the repeater must be included in the cable length calculation.

For a CRep S4 repeater, the typical and maximum propagation delays is 130ns and 200ns, respectively. Assuming a 5.5ns/m propagation delay for cable, the maximum propagation delay through the repeater is equivalent to a cable length of roughly 37m (rounding-up).

500kbit/s100 – 37 = 63m
250kbit/s250 – 37 = 213m
125kbit/s500 – 37 = 463m
50kbit/s1000 – 37 = 963m

Specifications

Layout and Connection

The CRep S4 device includes 4 CAN segments, wired by terminal blocks with 3 clamps. The power supply of CRep S4 is separately wired by a terminal block with 2 clamps.
