mpatible RTB plug; 1492-RTB8N (screw-style terminals) or 1492-RTB8P (push-in style terminals). Order plugs separately.
(2) Cables are available in lengths of 0.5 m, 1.0 m, 2.5 m, and 5.0 m. To order, insert the code for the desired cable length into the catalog number in place of the x: 005=0.5 m,
010=1.0 m, 025=2.5 m, 050=5 m. Example: 1492-ACABLE025TB is for a 2.5 m cable, and the letters TB.

(1) Cables are available in lengths of 0.5 m, 1.0 m, 2.5 m, and 5.0 m. To order, insert the code for the desired cable
length into the catalog number in place of the x: 005=0.5 m, 010=1.0 m, 025=2.5 m, 050=5 m. Example: 1492-
ACABLE025TB is for a 2.5 m cable, and the letters TB.
(2) Each cable for analog I/O has an overall shield with a ring lug on a 200 mm (8.87 in.) exposed drain wire at the
I/O module end of the cable.
(3) Not every connection is always used.
