The EC9648 is a microprocessor-controlled displaying, monitoring
and controlling device for universal use.
It has a universal input for standard signals (0..20 mA, 4..20 mA,
0..50 mV, 0..1 V, 0..2 V and 0..10 V), resistance thermometers
(Pt100 and Pt1000), thermocouples (type J, K, N, S and T) and frequency (TTL and switch contact). Additionally the device provides
functions like flow measurement, rotation speed measurement and
counter.
The EC9648 has switching outputs which can be configured as 2point controller, min/max alarm, 3-point controller, 2-point controller
with min/max alarm, etc. The state of the switching outputs (relays)
is indicated by LED “1” and “2”.
The EC 9648 saves the highest and lowest measured value in the
min/max value memory.
Furthermore it automatically detects impermissible operating states
like display or system error and displays a corresponding error
code.
