TRANSMITTER Z202-LP

GENERAL FEATURES

The Z202-LP module is a loop-powered voltage transmitter that measures the alternate
(mean value adjusted to the rms value) and direct voltage input value and converts it into a
current signal output. The instrument stands out for its precision class, low power
consumption and wide range of configuration options.
These are its general features:
Voltage input up to 500Vac in 5 preset ranges, which can be selected by DIP-switch.
Each range can be set and extended to the next one, and it's possible to calibrate the
instrument on any intermediate point in the continuous range of 0..500 Vac, without
either over-setting the fixed ranges, or opening the instrument (multi-rev trimmer
accessible from front panel).
High precision class: 0.3 (on 300 Vac of maximum range).
Wide range of frequency input (20 Hz..400 Hz).
Extremely short response time (< 100 ms).
3750 Vac galvanic insulation between voltage input and output ports.
Low output ripple and fast response time to input change.
