The 2800 series field displays are modular and easy
to assemble. According to customers wishes. The
basic construction consists of mother board with tree
slots, A, B and C. Slot A determines meter type and
provides always input signal. Slot B and C are inter-
changeable. As factory delivery input signal is always
installed into slot A , mA output into slot B and alarms
into slot C. In case of f.ex 4 alarms and relay card with

Slots A-C
Change of meter type:
Input card is placed always to
slot A. By changing input card
you can get an other type of
meter. You can change meter
with pulse input to meter with
current input, thermocouple,
strain gage etc.
Additional slots:
Additional cards provide output
4..20 mA, alarms, serial interface,
BCD output etc. Meter data sheet
dictates possible combinations.
grey connectors allow line voltage
110..240 VAC
(relay contacts).
Power supply:
There are two different mother
boards power supply
85..240VAC and 12..32 VDC.
mother board accepts
24 VAC. Connectors are colour
coded.
only closing or opening relay contacts, you need only
one relay card with 4 relays placed into slot C. The
slot B is now usable for other optional outputs.
You can have different types of meters by only
changing the input card in slot A. Data sheet of each
type of meter dictates the possible combinations.
Recalibration of card is not needed; only scaling and
other settings must be set by front panel keys.
All cards have calibration
