Introduction
Analog multi-functional terminal, 2-channel analog input + 2-channel analog output, ±10 V, ±20 mA, 16 bit, 2 ksps
The EL4374 analog input terminal combines two analog inputs and two analog outputs that can be individually parameterized by the controller/TwinCAT via CoE for current or voltage operation. Depending on the setting, the channels process signals with 2 ksps in the range from -10/0 to +10 V or -20/0/+4 to +20 mA.
The inputs are digitized with a 16 bit resolution and transported electrically isolated to the higher-level automation device - the 16 bit resolution outputs also work accordingly. With a technical measuring range of ±107% of the nominal range, the terminal also supports commissioning with sensor values in the limit range and the evaluation according to NAMUR NE43. The outputs are also capable of delivering up to ±107% of their capacity.
Special features:
- combined input/output terminal for standard/unit signals 10 V and 20 mA
- ±107% measuring/output range
- high output power at 20 mA: load up to 750 ohm
- 2 ksps conversion rate per channel for standard automation task
- Output diagnostics (short circuit at voltage output, wire break at current output)
