Accessories

P1015-18 Quick Connect to Screw Adapter

Screw adapter terminal designed for use with

all modules with 0.25 in. (6.35 mm) male quick

connect terminals.

C103PM (AL) DIN Rail

35 mm aluminum DIN rail available in a 36 in.

(91.4 cm) length.

P1023-20 DIN Rail Adapter

Allows module to be mounted on a 35 mm DIN

type rail with two #10 screws.

External Resistance vs.Time Delay

This chart applies to externally adjustable part numbers.

The time delay is adjustable over the time delay range selected by varying

the resistance across the RT terminals; as the resistance increases the tie

delay increases.

When selecting an external RT, add the tolerances of the timer and the RT

for the full time range adjustment.

Examples: 1 to 50 S adjustable time delay, select time delay range 1 and

a 50 K ohn RT. For 1 to 100 S use a 100 K ohm RT.
