2.3 Technical Specifications
2.3.1 Analog Inputs
Table 2-3 - Analog Inputs
Analog
conversion type:
10-bit A/D converter
Number of
Inputs: 6
Type of analog
input:
(configurable
via software
parameter) NTC Emerson Retail Solutions
(-50T110°C; 10K
Ω ±1% at 25°C)
PTC Emerson Retail Solutions
(-55T115°C; 990
Ω ±1% at 25°C)
Digital input (potential free
contact)
Voltage: 0 - V, 0 - 5V, 0 - 10V
(input resistance 3.7K
Ω )
Current: 0 - 20mA, 4 - 20mA
(input resistance 100
Ω )
Accuracy: NTC, PTC: ±1
0-1V: ±20mV
0-5V: ±100mV
0-10V:±200mV
2-20mA, 4-20mA: ±0.30mA
Additional
power:
+12V: 200mA in total (between
+12V and analog outputs)
+5V: 100mA
CAUTION! Any inputs that are powered
with a voltage that differs from that supplied
by the device (+12V or +5V) must be pow-
ered separately with another transformer (do not use
the same secondary of the controller’s power) in or-
der to prevent the inputs from malfunctioning or be-
ing damaged.
2.3.2 Digital Inputs
Table 2-4 - Digital Inputs
Type:
(configurable
via software
parameter) Opto-insulated live contact
(24VAC/DC)
External power 24VAC/DC ±20%
Number of
Inputs: 11
Digital input
status variation
detection time: 100ms (in any case it depends on
the cycle time set by the user in
the given application)
CAUTION! Use another transformer (do
not use the same secondary of the control-
ler’s power) in order to prevent the inputs
from malfunctioning or being damaged.
