PRODUCT HIGHLIGHTS

LOWER INSTALLATION COSTS

For repeat cycle applications, a single 342 timer does the job of

two ordinary timers. Installation cost is cut by more than half; a

single panel cutout is required and wiring is simplified since the

342 is prewired to perform flip-flop repeat cycle timing control.

MULTIPLE RANGES REDUCE INVENTORY REQUIREMENTS

The 342 incorporates six switch-selected ranges for each of its

two timing circuits. A single 342 thus provides any dial-adjustable

timing period between 50 ms and 10 hours for each cycle of the

flip-flop operation. Thus you need stock only one timer—and only

one model of that timer—to satisfy all your needs.

PROGRAMMABLE RELAY OPERATION

The 342’s DPDT relay can be energized either during the first

timing cycle (T1) or during the second (T2) simply by moving a

push-on connector from one programming pin to another on the

circuit board. Thus you can change load operation from one set

of contacts to the other (N O to N C) without changing the wiring.

CYCLE PROGRESS INDICATION

The 342’s two pilot lights provide a unique and effective method

of cycle progress indication in the minutes and hours timing

ranges ... blinking at an ever-increasing rate as the cycle

progresses. In the 1 and 10-second ranges, the pilot light is off

before timing cycles and steady on during timing.

DESIGNED FOR INDUSTRIAL SERVICE

In the 342, a number of features and characteristics have been

incorporated to ensure a long trouble-free life expectancy, even

in difficult industrial environments: transformer-isolation for high

noise immunity; reliable relay rated for 100,000,000 mechanical

operations; oscillator-based timing circuit for high accuracy

even with changes in temperature and voltage; and a versatile

mounting capability in a compact housing that is dust and

impact-resistant.
