Product overview
EL31xx-00xx
29
Version: 5.9
4-channel analog input, -10/0…+10 V (-3/0...+3 V), -20/0/+4…+20 mA, 16 bit
The EL3174, EL3174-0090 and EL3174‑0002 analog input terminal has four individually parameterisable
inputs. Signals in the range from -10/0 to +10 V or -20/0/+4 to +20 mA can be processed per channel. The
EL3174‑0032 measurement ranges are identical but for voltage from -3 V to + 3 V.
Each channel should be set by the controller/TwinCAT to U or I mode via CoE. The input voltage or the input
current will be digitalized with a resolution of 16 bit incl. sign and transported electrically isolated from the
fieldbus to the higher-level automation device. With a technical measuring range of ±107 % of the nominal
range, the terminal also supports commissioning with sensor values in the limit range and diagnostics
according to NAMUR NE43.
In addition to the full functionality of the EL3174, the EL3174-0090 supports TwinSAFE SC (Single Channel)
technology. This enables the use of standard signals for safety tasks in any networks of fieldbuses.
•
EL3174/ EL3174-0090:
◦ Feeding of Voltage and current signal on different terminal points
◦ The voltage inputs operate differential
◦ The current inputs operate single ended to reference ground
◦ EL3174-0090 additionally supports TwinSAFE SC technology
•
EL3174‑0002/ EL3174‑0032:
◦ Common used inputs for voltage and current. After the terminal have been switched on, the
channel is in high impedance voltage mode and a connected, already operating current sensor
with mA output have to strain against the high liability as long as the channel is switched into the
mA operation mode via EtherCAT.
◦ The voltage inputs operate differential
◦ The current inputs operate differential
◦ The four differential inputs of the EL3174‑0002/ EL3174‑0032 are electrically isolated against each
other and against the fieldbus (2,500 V DC testing voltage, 7 seconds production test).
107% Extended Range
The EL3174/ EL3174‑00xx are preconfigured to a measurement range of 107% (e.g. 0x7FFF corre-
spond to +10.737 V or 3.22 V accordingly). You also can reset to the legacy range by CoE access.
Then 0x7FFF correspond to the full scale value or e.g. 10 V (3 V) as before.
