Table 1. Specifications for Fisher 3582 and 3582i Valve Positioners
Note: Specifications for 3582 positioners include
3582A, 3582C, 3582D, 3582G, and 3582NS unless
otherwise indicated
Input Signal
3582:
J 0.2 to 1.0 bar (3 to 15 psig), J 0.4 to 2.0 bar
(6 to 30 psig), or J split range, see table 10
3582i:
4 to 20 mA DC constant current with 30 VDC
maximum compliance voltage, can be split range, see
table 10
Equivalent Circuit for 3582i
The 582i converter equivalent circuit is 120 ohms,
shunted by three 5.6‐volt zener diodes
(see figure 10)
Output Signal
Type: Pneumatic pressure as required by actuator up
to 95 percent of maximum supply
Action: Field‐reversible between J direct and
J reverse within the pneumatic valve positioner
Supply Pressure
(1)
Recommended: 0.3 bar (5 psi) above actuator
requirement
Maximum: 3.4 bar (50 psig) or pressure rating of
actuator, whichever is lower
Supply Medium: air or natural gas
(2)
Note: The 3582i is not approved for use with natural
gas as the supply medium
Input Bellows Pressure Rating

Electromagnetic Compatibility for 582i
electro‐pneumatic converter
Meets EN 61326‐1 (First Edition)
Immunity—Industrial locations per Table 2 of
the EN 61326‐1 standard. Performance is
shown in table 3 below.
Emissions—Class A
ISM equipment rating: Group 1, Class A
Note: The electromagnetic compatibility
specifications also apply to the 3582i
3582 and 3582i
Typical Open Loop Gain (Output Signal):
J 100 in the range of 0.2 to 1.0 bar (3 to 15 psig)
J 55 in the range of 0.4 to 2.0 bar (6 to 30 psig)
Operating Influences
Supply Pressure—3582: Valve travel changes less than
1.67 percent per bar (0.25 percent per 2 psi) change
in supply pressure
Supply Pressure—3582i: Valve travel changes less
than 3.62 percent per bar (1.5 percent per 2 psi)
change in supply pressure
