EVM32 Specifications
Parameter
Specification
Power (DC input)
V+ ..................................................................... User-supplied voltage that drives output circuitry.
V+ range ........................................................... 12-24VDC.
V+ current ......................................................... 1.5A @ 12VDC or 0.75A @ 24VDC;
plus the sum of the load current on outputs that are in sourcing mode.
Environmental
Operating temperature ...................................... 32 to 122
°
F (0 to 50
°
C)
Storage temperature ......................................... -22 to 185
°
F (-30 to 85
°
C)
Humidity ............................................................ 0 to 95% non-condensing
Dimensions
EMV32 module ................................................. 3.3 inches x 6.25 inches (83.82 mm x 158.75 mm)
Digital Inputs
Switching levels ................................................ Low
≤
1/3 V+ voltage; High
≥
2/3 V+ voltage.
Voltage range ................................................... Voltage range = 0-24VDC. Voltage of input signals should not exceed voltage level of
V+. (Input circuitry of EVM32 has diodes to protect against voltages that exceed V+,
but performance may degrade.)
Sinking/Sourcing ............................................... Sinking: Connect jumper for selected SIM board to position 3 (factory default).
Sourcing: Connect jumper for selected SIM board to position 1.
Impedance ........................................................ 6 K
Ω
, minimum. Requires input current (sinking or sourcing) of 0.111mA per volt of
user-supplied voltage to V+ (e.g., 2.67mA if V+ = 24V).
Active level ....................................................... Set by the 6K controller (
INLVL
command setting) — default is active low, but can
be set to active high.
Input frequency ................................................. 50 kHz (the maximum frequency is limited practically to 500 Hz by the 2 ms update
rate of the 6K controller).
Status ............................................................... Check with the
TIO
command.
Digital Outputs
Sinking/Sourcing ............................................... Sinking: Connect jumper for selected SIM board to position 3 (factory default).
Sourcing: Connect jumper for selected SIM board to position 1.
Voltage (sinking — jumper in position 3) ........... Output voltage level is less than or equal to 0.4VDC when sinking up to 50mA.
(
≤
0.4 VDC for 50 mA).
Output voltage level is less than or equal to 2.5VDC when sinking up to 300mA.
(
≤
2.5 VDC for 300 mA).
Voltage (sourcing — jumper in position 1) ......... Output voltage level may be up to 2 volts less than the user-supplied voltage V+
when sourcing up to 50mA.
Output voltage level may be up to 2.5 volts less than the user-supplied voltage V+
when sourcing up to 300mA.
Current .............................................................. 300mA maximum per output; continuous duty at 50
°
C ambient temperature.
Active level ....................................................... Set with the
OUTLVL
command — default is active low.
Rise time, Fall time ........................................... Load dependent; typically 40ns per 1000 pF.
Under-voltage protection ................................... The under-voltage lockout circuit is meant to prevent the output driver from sinking or
sourcing when the user-supplied voltage at V+ drops below +5VDC.
Thermal shutdown ............................................ The thermal shutdown protection is intended to protect the device from marginal
environmental factors. It must not be considered short circuit protection. The
thermal resistance between the FET junction and the thermal protection circuit on the
SIM cards is great enough that the rapid rise in junction temperature caused by a
short circuit will not transfer fast enough to protect the device from damage.
Short-circuit protection ...................................... Digital outputs are NOT short-circuit protected.
Status ................................................................ Check with the
TIO
command.
Analog Inputs
Input voltage range ........................................... 12-bit A/D converter,
±
10VDC; unipolar/bipolar range selectable
ANIRNG
command.
Unipolar: 0V to 10VDC, or 0V to 5V;
Bipolar: -10 to +10V (factory default), or -5V to +5V.
Input current (worst case load) .......................... Unipolar: 720
µ
A @ 0V to 10VDC range; 360
µ
A @ 0V to 5V range.
Bipolar: -1200
µ
A @ -10V and 720
µ
A @ +10V; -600
µ
A @ -5V and 360
µ
A @ +5V.
Input dynamic resistance .................................. Unipolar: 21K
Ω
; Bipolar: 16K
Ω
Fault tolerance ..................................................
±
16.5V
Sample rate ...................................................... Each input requires 2ms (e.g., 4 ms for 2 inputs, 16ms for 8 inputs); therefore, to
maximize performance, you should disable unused inputs with
ANIEN
command.
Status ................................................................ Check with the
TIO
command.
