The ED4078 analog output terminal is a universal 10 V/20 mA output module in the 16-bit class for simple control tasks. Standard signals in the -10/0...+10 V or -20/0/+4...+20 mA ranges can be generated per channel. CoE can be used to set each channel to U or I mode in TwinCAT or from the controller.
The voltage and current outputs are single-ended, meaning that they each refer to the 0 V DC power contact. All outputs are digitized with a 16-bit resolution and transmitted to the higher-level automation system under electrical isolation. With a technical output range of ±107% of the nominal range, unconventional setpoints, such as for error reporting purposes, can also be output. The current outputs can have high load resistances and report overload, wire break, or – in the case of voltage outputs – a short circuit.
Special features:
- combined output terminal: 10 V/20 mA
- output range ±107%
- 2 ksps conversion rate per channel for standard automation tasks
- high output power at 20 mA: load up to 300 Ω
- output diagnostics: short circuit for voltage output, wire break for current output
The ED-series EtherCAT Terminals have push-in connection technology which makes wiring easy and tool-free.
