BNC In-line

Terminators

A Modicon 60-0513-000 BNC In-line Terminator is used to terminate the end of a

drop cable for nodes that require external 75 Ω termination with BNC-type

connections—i.e., the older J890/J892-00x Adapters and the Modicon 410 and

3240 Motion products (see the list in RIO Network Cable System, p. 16).

The 60-0513-000 In-line Terminator has two BNC connectors—a female for the

incoming drop cable and a male to connect to the drop adapter. It has a return loss

of 20 dB (VSWR 1.2:1), a frequency range from DC ... 300 MHz, and an insertion

loss of 0.03 dB.

Self-terminating

BNC Adapters

for Hot Standby

Systems and

Drop Cables

Modicon 52-0370-000 Self-terminating BNC Adapters are used in 984 Hot Standby

systems and on drop cables. They allow one Hot Standby PLC to be disconnected

from the network without causing open-circuit communications errors in the other

PLC. Used on the end of a drop cable, they maintain proper termination when an

RIO drop is removed from the network. One side of the terminator has a female F

connector, and the other side has a female BNC connector. The adapter stays on

the cable active side and only the BNC side should be disconnected while the

network is operating. Disconnecting the F connection side will cause an impedance

mismatch on the trunk.

The 52-0370-000 Self-terminating BNC Adapter has a return loss of 40 dB, a

frequency range from 100 kHz ... 30 MHz, and an insertion loss of 0.03 dB.
