Foxboro SMI983-I7ZZZN-L Positioner

SMI983-I7ZZZN-L Electrical Position Transmitter

The electrical position transmitter SMI983 converts the linear or rotary movement of a valve/actuator into a 4 to 20 mA standard electrical signal. The configuration of the feedback signal in correspondence to the position of the actuator is easily performed by the two push-buttons.
For complete specifications, refer to Product Specification Sheet PSS EVE0202 A-(en).g  Non-reactive conversion of valve-/actuator-position into 
a load-independent 4 to 20 mA DC signal 
g  Two-wire circuit 
g  Easy adjustment of zero and span by two push buttons
g  Operating condition is displayed by two LEDs
g  Easy configuration of the feedback signal from ‘direct’ to ‘reverse’
g  The feedback signal can be randomly adjusted between 4 to 20 mA
g  Wear-free, high linear scanning with conductive plastic precision potentiometer 
g  Mounting on linear actuators according to NAMUR:
IEC 534 Part 6 
Stroke range 8 to 100 mm (0.3 to4 in) 
(larger strokes on request)
g  Mounting on rotary actuators acc. to VDI/VDE 3845 for rotation angles up to 120°
• Angular range 
 linear: 30° to 120° 
 equal percentage: 90°; linear from 70°
g  Protection class IP54 or IP65
g  Explosion protection:
• II 2 G EEx i (intrinsic safety) according to ATEX 
• Intrinsic safety according to FM (in preparation)
g  Ambient temperature* –40 to 80°C (–40 to 176°F)
g  EMC in accordance with international standards and laws (CE)
