NTRODUCTION

The Digital Futronic module uses the latest integrated microcontroller technology to enable one
electronics module to perform valve actuator modulating and positioning control from analog control
signals. The control module uses EIM’s M2CP TBM01 termination panel for interface of all analog control
types. The Digital Futronic module converts 4-20mA analog input to digital for processing and from digital
to 4-20mA analog output for position feedback. The Digital Futronic module controls four EIM motor
control starter types.

1) Futronic II Electro-mechanical AC motor starter

2) Futronic III SCR H-Bridge Solid-state DC motor starter (Powered by 115VAC, 1-Ph)

3) Futronic IV Triac Solid-state (SSR) AC motor starter

4) Futronic VII MOSFET Solid-state pure DC motor starter (Powered by 24VDC or 48VDC)

EATURES AND SPECIFICATIONS

Digital microcontroller adapts to any actuator and valve size, speed/stoke-time, process pressure, etc. by
automatically tuning controls to obtain maximum accuracy without any user adjustments for dead band,
delay time, etc.

Automatic calibration of position input to valve travel limits.
Built-in protection for motor and motor controls.
DC motor speed control for Futronic III and Futronic VII.
Easy setup and calibration to user’s external analog control signal input and analog feedback output. All

setup and calibration adjustments by on-board DIP switches and two miniature push buttons.
LED indicators for normal/fault operating conditions, setup mode, loss of analog signal, and solid-state

motor control output.
Isolated Analog Input: 4-20mA with 12-bit (.025%) resolution (calibration range of 0-24mA). 210 Ohms

input resistance. Operates from 10V to 32V loop supply. Allows up to 750 Ohms loop resistance at 24V.
Isolated Analog Output: 4-20mA with 16-bit (.0015%) resolution (calibration range of 0-24mA). Drive loop

resistance up to 750 Ohms. True current source with internal 24VDC power supply. No external power
source required to power loop. Internal automatic resetting fuse for 24VDC power supply.

Isolation dielectric strength: 2500V AC for 1 Minute (Input to output and I/O to ground).
Inverted Analog I/O Option: where 20mA = close valve position and 4mA = open valve position.
Go To Default Position Option: On loss of control signal, user selected default valve position anywhere

between 0 and 100%.
Control Accuracy: Futronic II mode +/- 1.0% @ 15 second stroke time or greater

Futronic III mode +/- 0.25% @ 15 second stroke time or greater
Futronic IV mode +/- 0.5% @ 15 second stroke time or greater
Futronic VII mode +/- 0.25% @ 15 second stroke time or greater

Nonlinearity: <0.05% of calibrated analog input and output over full range of 0-100%.
Operating Temperature Range: -40C to +85C (-40F to +185F), Humidity: 10% - 95% (Non-condensate)

NSTALLATION AND WIRING

Refer to the wiring diagram supplied with the actuator for wiring details and options supplied with the
system. Figure 1 below is generic and provided primarily for wiring 4-20mA analog input and output
signals. Refer to Figure 1 for proper wiring of analog I/O and associated polarities relative to external
equipment and power supplies. Use the following rules when wiring analog I/O signals.

1) Route analog I/O cables into actuator enclosure through separate conduit entries from power wiring.

2) Always use twisted-pair instrumentation cable for wiring 4-20mA analog input and output signals.

3) Use shielded cable when analog signals are being installed in or routed through high noise areas.

4) If shielded cable is used, earth ground the shield by connecting only one end of the shield to earth.

5) Instruments or control equipment must source current to the analog input of the Digital Futronic.

6) Remote current source to analog input must have own power source, or an external supply is required.

7) Do not connect an external power source to the 4-20mA analog output of the Digital Futronic module.

8) The Digital Futronic module contains its own internal 24VDC power supply for the 4-20mA output and
sources current to external instruments or control equipment.
