Measured values:
Range:
2 x temperature by an external
Guilcor
Pt1000/0 probe
2 x binary input intended for voltage to be applied to
it or a voltage-free contact (an open-collector
transistor) to be connected to it. This device is not
suitable for c
atching the „voltage applied/not applied”
states
.
Temperature: (-200 to +
260) °
C, Pt1000/3850 ppm
Measuring current: ca 0.5 mA in ca 60 ms long pulses
Both voltage and no-voltage contact can be connected
to the binary input without the need for configuration.
Voltage levels:
„L“ level
input voltage:
< 0.8 V
(*)
„H“ level input voltage:
> 2 V
Minimum voltage applicable: 0 V
Maximum voltage applicable: +30 V DC
(*)
The voltage necessary for establishing the „L“
level must factually be applied. Should the input be
disconnected, the device will sense the „H“ level.
Parameters of the voltage-free contact:
Contact resistance in „switched
-
on“ state:
< 10 kΩ
Contact resistance in the „switched
-
off“ state:
> 2 M
Ω
Excitation voltage: approx. 3 V
Minimum state duration necessary for latching
the state: 1s
Input accuracy (without probes):
±0
.
2 °C in the range of
-20
0 to +100 °C
±0
.2 % of the measurement value in the range
of +100 to +260 °C
The accuracy of the device with the temperature probe
connected is determined by the above input accuracy
and the accuracy of the probe used.
Connection mode:
Split connection block, maximum wire cross section
1.5 mm
2
. Recommended length of the Pt1000 probe
cables is maximum 15 m, a length of 30 m should not
be exceeded. Maximum length of the binary inputs
cables is 30 m. It is recommended to use shielded
cables.
CAUTION: The inputs are not galvanically separated!
