GENERAL
The catalogues of timers and counters
are often packed with different models
and versions: the 550 offers one model
for every application.
By limiting the number of faceplate keys
to those strictly necessary, there is a larger space for the display.
The miniaturisation achieved with SMT
reduces the dimensions and increases
the reliability.
The microprocessor enables the required
performance to be selected, by means of
setting only three parameters (Typ, out,
in.2) by following the configuration described later.
There are two settings SP1 and SP2, five
time bases: from hundredths of a second
to hours and minutes, five prescaler ranges for the counter.
TECHNICAL DATA
INPUTS
2 inputs (IN1, IN2) with start/stop or reset
function of the timer or counter, and counter input for frequencies up to 100Hz.
IN1
From voltage free contacts, open collector (24Vdc/1mA) or in Vac (at the same
voltage as the instrument supply).
IN2
Available only if IN1 is not in Vac, for voltage free contact or open collector
(24Vdc/1mA), active either when closed
or when open.

Delay timer
Relay 1 repeats the variation in the command signal on IN2 with a delay pulses time
t (=SP1). To function correctly, tk>t, where tk is
the pulse duration of the command pulse.
typ = 4
out = 9
in2 = 1
Non cyclic single timer, with reset
The timer is activated by a command on IN1.
Relay 1 energises at the end of the preset time t (=SP1) and disenergises with a
command on IN2 (reset). The action of relay 2 depends on the configuration of OUT.
typ = 0
out = 1÷4
in2 = 1
Non cyclic double timer with reset
The timing begins if there is a command signal on IN1. Relay 1 disenergises for the
preset time t1 (=SP1) and energises for the preset time t2 (=SP2). It then rests
except when the setting Out=6. To begin a new cycle, a command signal on IN2 is
required (reset). The action of relay 2 depends on the configuration of OUT.
typ = 1
out = 1÷6
in2 = 1
Non cyclic double timer without reset
The timing begins with a command signal on IN1.
Relay 1 disenergises for the preset time t1 (=SP1) and energises for the preset time
t2 (=SP2) if then rests except in the case of setting Out=6. The timer is reset by
removing the command on IN1. The action of relay 2
depends on the configuration of OUT.
typ = 1
out = 1÷6
in2 = 0
Non cyclic single timer, without reset
The timing begins with a command on IN1.
Relay 1 energises at the end of the preset time t (=SP1) and disenergises when the
command on IN1 is removed.
The action of relay 2 depends on the configuration of OUT.

Double cyclic timer
The timer is activated when there is a command signal on IN1. Relay 1 remains disenergised for a preset time t1 (=SP1) and energises for a time t2 (=SP2). When time
t2 has expired, the cycle begins again at t1. It repeats the cycle continuously. The
action of relay 2 depends on the configuration of OUT.

Revolution monitor
The unit becomes active when there is a command signal on IN1.
The two relays remain disenergised when the time between two pulses is between
time t1 (=SP1) and t2 (=SP2). If the time exceeds t1, relay 1 energises. If the time is
shorter than t2, relay 2 energises..

Cyclic double counter
The countdown starts at the value n1 (=SP1). When the zero is reached, the value
n2 (=SP2) begins to countdown to zero. When this count has reached zero, n1
begins to countdown once more.
Relay 1 is disenergised during the
countdown of n1 and is energised
during the countdown of n2.

Cyclic monostable counter with block count
The countdown begins at the preset value n (=SP1) and continues down to zero.
The pulses at IN1 are counted while there is a command signal on IN2. When zero is reached,
relay 1 is energised.
The relay remains energised for a time t (=SP2),
after which the cycle starts again at the beginning.

from the beginning and relay 1 is energised.
The relay remains energised for a time t (=SP2).

FUNCTIONALITY
Standard counter
The countdown begins at the preset value n (=SP1), and continues down to zero.
The pulses on IN1 are counted while there is a command signal on IN2. Relay 1
energises when the count reaches zero and
disenergieses again when the command signal
on IN2 is removed. The function of relay 2
depends on the configuration of OUT.

when the zero is reached and remains energised for a time t (=SP2). Relay 2 depends on
the configuration of OUT.
