Bulletin 1485 PowerTap Connection

IMPORTANT: Power: 15.0 Amps maximum total current; 7.5 Amps each trunk at 25°C (1485T–P2T5–T5).

Power: 6.0 Amps maximum total current; 3.0 Amps each trunk at 25°C (1485T–P2T5–T5C).

ATTENTION: Under some conditions of load

current and ambient temperature the fuse current

value should be decreased. As shipped, the

1485T–P2T5–T5 PowerTap connection is fused to

supply up to 7.5 Amps to one trunk line, the

1485T–P2T5–T5C 3.0 Amps.

Description

For power requirements on your DeviceNet network,

Allen-Bradley is introducing its PowerTap connection. The

PowerTap connection is a passive coupling device used to

limit trunk current and is also used to permit the connection of

multiple power supplies to the trunk without mutual

interference.
