2 Product and functional description
2.1 Use as intended
The EA16 is a measuring value display unit for measuring transducers with out-
put signals for current and voltage acc. to IEC 60381. Up to four measuring
transducers in two or three-conductor versions can be connected.
Typical applications
• Measured value display in clean room
Important features
• 3.5" (8.9 cm) TFT Touch LCD colour display
• Configurable colour switching
• 2 or 4 channel mode with …
– 2 or 4 configurable analogue inputs
for uniform signals (0/4 … 20 mA, 0 … 10 V) acc. to IEC 60381
(signal ranges ca be selected freely within the limits; see Technical
Data)
– 2 or 4 configurable analogue outputs
with possibility of characteristic curve spread and reversal with any off-
set
– 2 or 4 configurable switching outputs
with potential-free relay contacts or semiconductor switches
• USB interface
• Optional Modbus RTU interface
• Optional data logger function with data storage on Micro SD card
• Configuration of all parameters and a measuring point protocol
