universal indicator controller / LED / recessed
On/off control mode
● Universal input for standard signals, frequency,
Pt100/Pt1000 and thermocouples
● Switching outputs variably configurable
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
The EC9648 has switching outputs which can be configured as 2-
point 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
