EL3072 - Introduction

The EL3072, EL3074 and EL3078 analog input terminals are universal 10 V/20 mA input modules in the 16‑bit class for simple control tasks.
Signals in the range -10/0…+10 V or ‑20/0/+4…+20 mA can be processed by each channel.
Voltage and current signals are connected to different terminal points. Each channel can be set to U or I mode. in TwinCAT or by the controller via CoE.

The voltage and current inputs are single‑ended. This means that one channel connection point in each terminal is connected to +24 V or 0 V (power contacts).

All inputs are digitized with a resolution of 16 bits and transmitted electrically isolated to the higher-level automation device.
With a technical measuring range of ±107% of the nominal range, the terminal supports both commissioning with sensor values in the limit range and evaluation in accordance with NAMUR NE43.

The EL3072 has two individually parameterizable inputs and supports the 2‑, 3‑ and 4‑wire connection. It can supply sensors directly with +24 V.

Special features:

• combined input terminal: 10 V / 20 mA
• Measuring range ±107%
• 2 kSps conversion rate per channel for standard automation tasks
