Digital display with analogue inputs
Type DA5-IU-C
1.1 Safety instructions and warnings
Only use this display
– in a way according to its intended
purpose
– if its technical condition is perfect
– adhering to the operating
instructions and the general
safety instructions.
1.2 General safety instructions
1. Before carrying out any installation or mainte-
nance work, make sure that the power supply
of the digital display is switched off.
2. Only use this digital display in a way according
to its intended purpose: If its technical condi-
tion is perfect.Adhering to the operating in -
structions and the general safety instructions.
3. Adhere to country or user specific regulations.
4. The digital display is not intended for use in
areas with risks of explosion and in the
branches excluded by the standard EN 61010
Part 1.
5. The digital display should only operate if it has
been correctly mounted in a panel, in accor-
dance with the chapter “Technical features”.
1.3 Use according to the intended purpose
The digital display may be used only as a panel-
mounted device. Applications of this product may
be found in industrial processes and controls, in
manufacturing lines for the metal, wood, plastics,
paper, glass, textile and other processing indus-
tries.
Over-voltages at the terminals of the digital dis-
play must be kept within the limits in Category II
If the digital display is used to monitor machines
or processes in which, in case of a failure of the
device or an error made by the operator, there
might be risks of damaging the machine or caus-
ing accidents to the operators, it is your responsi-
bility to take appropriate safety measures.

2. Inputs
LATCH (Connect 4)
Static input freezing the displayed value.
If this input (pnp) is supplied with
4 ... 30 V DC the actual value is frozen until the
input is released or the signal level gets below 2
V DC. The calculating of max. and min. value is
not af fec ted.
CURRENT INPUT (Terminal 5)
Analogue current input with reverse connection
pro tec tion and current limitation to max. 50 mA.
Connect the signal line with the an sig-
nal with this input.
Caution: To prevent interfering signals caused
by the supply voltage, this input is isolated from
the supply voltage. Thus, for the measurement,
connect the signal line with the most negative
signal to the analogue reference input.
VOLTAGE INPUT
(Terminal 7)
Analogue voltage input. Connect the signal line
with the an signal with this input. In case
of reverse connection, the display shows „Err4“.
