The displays Q-DISP-C, prepared for
mounting on the back panel, 96x48mm, will
allow you to count and totalize.

It is possible to have a high power or low
voltage AC / DC and have up to congurable
outputs of relay outputs and analog outputs

1. Meter Q-DISP-C

Panel meter 96x48mm counter, ratemeter, periodmeter

Panel meter congurable as impulse counter, ratemeter and
periodmeter. Accepts wide range of signal types such as
Push-pull, NPN, PNP, Namur, TTL, inductive, mechanical,
... also monodirectional and bidirectional encoder signals
(quadrature signals).

Highly congurable, with pull-up/pull-down resistors, trigger
levels, pulse detection on raising or falling edge, excitation
voltage and antirrebound lters. ‘Trigger Sense’ utility for easy
trigger level adjustment.

Scalable reading by congurable multiplier and divider fac­tors (1 to 999999). Congurable decimal point position.
Resolution 6 digits (999999/-199999).

Excitation voltage congurable to 5V, 9V, 15V and 18V.

Up to 3 relay outputs controlled from the instrument alarms,
can be increased to 6 relay outputs (with simplied function­ality, see section 2). Congurable direct access to setpoint
values modication on key UP (5).

Standard 96x48mm DIN size. Universal AC and DC power
options. Up to three control and/or signal retransmission
modules. IP54 front protection, with optional IP65.

Connections via plug-in screw terminals and conguration via
three front push-buttons. For industrial applications.

Counter modes

Counter functionality allows to choose between 5 counting
modes (simple counter, quadrature counter, counter with
inhibit control, differential counter and counter with add/sub­stract control). Instrument has two impulse input channels
(A and B) and selectable ascending or descending counting
modes.

Reset function is accessible from rear terminal and front
push-button. The front reset can be enabled or disabled. Con­gurable preset value. Alarm activation can be associated
to an action : ‘reset to zero’, ‘return to preset’ or ‘no action’.
Relays activation and deactivation times are independent
and congurable.

Alarm functions with ‘reset to zero’ or ‘return to preset’ create
a continuous counting cycle (instrument cycles from ‘preset
value’ to ‘alarm value’). Instrument provides a internal cycle
counter, accessible to the operator.

Memory retention in case of power loss or deactivation. When
power is back again, instrument recovers the last reading
and conguration.

Maximum counting frequency is 250 KHz in ‘FAST’ mode.

Ratemeter mode

Ratemeter function allows to choose between normal rate­meter (one single input channel) or bidirectional ratemeter
(quadrature ratemeter) with detection of clockwise / counter­clockwise sense of turn.

In ratemeter mode, the instrument counts the number of
impulses during a xed period of time, and calculates the
frequency.

For low frequency applications, a special ‘SLOW’ mode is
available, which offers the fastest response time for low fre­quency applications. See section 1.13 for more information.

Recursive lter ‘Average’ to stabilize unstable readings.

Maximum frequency in ratemeter mode is 900KHz and
minimum frequency (with ‘SLOW’ mode activated) is 0.001
Hz (1mHz).

Periodmeter mode

Periodmeter mode detects the signal time between impulses.
For long period applications, a special ‘SLOW’ mode is avail­able which offers the fastest response time for low frequency
applications. See section 1.13 for more information.

Earth connection - Although a terminal is
offered for earth connection, the connec­tion is optional. The instrument does not
need this connection for correct function­ing nor for compliance with the security
regulations.

Fuse - To comply with security regulation
61010-1, add to the power line a protection
fuse acting as disconnection element, eas­ily accessible to the operator and identied
as a protection device.
