1. INSTRUMENT DESCRIPTION

1.1

General description

TC42 is a microprocessor based digital timer/pulse coun-
ter/power limiter.
The instrument used as a timer offers the possibility to
program: up to 3 timings (Set point), 6 operating modes for
OUT1 output, 10 operating modes for OUT2 output, 4 time
scales (which allow a count from a maximum of 9999 hours
to a minimum of 0.01 seconds), 6 counting enabling func-
tioning modes and 2 counting modes (UP or DOWN).
The instrument used as a pulse counter offers the pos-
sibility to program: up to 2 Set points, 3 operating modes
for OUT1 output, 4 operating modes for OUT2 output and
offers the possibility of counting division.
Moreover, the instrument can also be used as a power
limiter by programming a duty-cycle from 0 ÷ 100% and a
total cycle time from 1 ÷ 900 s.
The upper 4-digit display normally shows the counting
status while the lower 4-digit display the selected timing
(set-point), the status of the outputs is shown by 2 LEDs.
The instrument has 1 counting/counting enabling input
(CNT) and 1 digital input with programmable operation
(RESET or reverse counting) whose signals can come from
free of voltage contacts, from devices with NPN or PNP
transistor output. It can have up to 2 relay outputs or for
driving Solid State Relays (SSR).
