ENVIRONMENT
Operating temperature -40ºC to +85ºC
Storage temperature -40ºC to +115ºC
PERFORMANCE - the following applies to the EX200 only, characteristics of the feedback element and actuator system
response will have additional effects.
Conversion 10 bit max normal conversion range (4-20mA) = 1 in 800.
O/P switch res. +/-1 bit theoretically, modified to up to +/-5% of span by dead band.
Accuracy (Theo.) 0.125% span based on conversion resolution of 1 in 800.
Accuracy (actual) 0.5% span based on 25% turn down of feedback range.
