I
NPUTS
2 inputs (IN1, IN2) with start/stop or reset functions for timer or counter and counter input with maximum frequency of 100Hz.
IN1
Available from voltage-free contacts, open collector (24Vdc/1Ma) or control in Vac (same voltage as instrument).
IN2
Available only if IN1 is not in Vac with control from voltage-free contact or open collector (24Vdc/1mA) active when open or closed.

Panel mounting.
Faceplate dimensions: 48x48mm./1.89”x1.89” (1/16DIN); depth: 100mm/3.94”
Cut-out dimension: 45(+0.6/-0)x45(+0.6/-0)mm/1.77” (+0.02/ -0)x1.77”(+0.02/-0)”.
To attach the instrument, insert the two brackets in the housings on the top and bottom of the case
and tighten with the screws. To mount two or more instruments in a row or column, use the clips
and respect the following cut-out dimensions:
Row: Base (48 x n) -3, (1.89”x n) -0.11” Height 92 (+0.8/ -0) /3.62” (+0.03/ -0)
Column: Base 45 (+0.6/-0)1.77”(+0.02/-0) Height (96xn)-4/(3.78”xn)0.15”
where “n” is the number of instruments.
CE MARKING:
The instrument conforms to the European Directives 2004/108/CE and
2006/95/CE with reference to the generic standards:
EN 61000-6-2 (immunity in industrial
environment) EN 61000-6-3 (emission in residential environment) EN 61010-1 (safety).
MAINTENANCE: Repairs may be done only by trained and specialized personnel. Cut power to
the instrument before accessing internal parts. Do not clean the case with hydrocarbon-based sol-
vents (trichloroethylene, gasoline, etc.). The use of such solvents will compromise the instrument’s
mechanical reliability. Use a clean cloth moistened with ethyl alcohol or water to clean external
plastic parts.
TECHNICAL SERVICE: GEFRAN has a technical service department. Defects deriving from any
use not conforming to this manual are excluded from the warranty.
