5. Configuration codes
To activate the desired input signal range, activate the range configuration
code (see Table 2) into ‘ configuration mode ’ (see section 10.2). See
connections at section 8.
INPUT SIGNAL RANGES
process 4/20 mA, 0/10 Vdc
type of signal active and passive, the instrument provides
excitation voltage to power the transducer.
excitation voltage +15 Vdc, max. 25 mA, shortcircuit protected
input impedance (mA) variable impedance, voltage drop on terminals <1.2 Vdc
input impedance (Vdc) 1 MOhm
maximum oversignal
*
25 mA for mA
25 Vdc for Vdc
*
‘maximum oversignal’ is the maximum signal accepted by the instrument. Higher signal
values may cause instrument damage. Lower values are non destructive but may be out
of accuracy specifications.
ACCURACY AT 25 ºC 0.5 % F.S. for mA, 0.3 % F.S. for Vdc
(see section 10.5)
THERMAL DRIFT <100 ppm/º (F.S.)
STEP RESPONSE
0 to 99 % of signal
<200 mSec. in ‘ Mode 1 ’, <550 mSec. in ‘ Mode 2 ’
(see section 10.5)
OUTPUT SIGNAL 1

Codes with ‘ no function assigned ’ will display message ‘ nA ’
indicating the code is ‘ not available ’.
To select the ‘ active ’ or ‘ passive ’ mA versions at the input and
output signals, configure the connection terminals as explained
at section 8.
To measure process signals and provide dual outputs in standard
4/20 mA signals. Inputs and outputs are isolated.
Single and dual signal retransmission to one or two remote acquisition
devices (HMI, PLC, Scada, ...). Local and remote verification of process
values.
