Electronic drivers type E-ME-T
analog, Eurocard format, for proportional valves with transducer
E-ME-T drivers control the current to
the solenoid of Atos proportional valves
with position transducer, regulating the
spool position or the flow according to
the electronic reference signal, adju-
sted by transducer’s feedback.
Features:
• bias regulation
• scale and dissymmetrical ramps
regulation
• voltage (standard) or current
(/I option) reference signal
• voltage (standard) or current
(/C option) feedback signal
• test point for reference and feedback
control on front panel
• factory pre-setted
• Eurocard format (DIN 41494 - plug-in
unit)
• electronic filters on input and output
lines
• CE marking granting the conformity
to the EMC Directive (Electro ma gne -
tic compatibility)
• both sides of the card with shielded
cover with E faston connector
Applications:
Position or flow open or closed-loop
regulation systems, according to the
block diagram .

T = driver for -T proportional valve with
transducer
01H = for single solenoid proportional valves
05H = for double solenoid proportional valves
Options:
- = standard with rising and falling ramps
/C = suitable to receive current feedback signals
4 ÷ 20 mA (available only for ex-proof and
armoured valves).
/I = suitable to receive current reference signal
4 ÷ 20 mA.
