The ETH-Optoin-8 is a compact 10/100Mbit Ethernet module with 8 optocoupler inputs for digital acquisition of voltages in the range of 5V to 30V. Four DIP switches facilitate the network configuration and a number of status LEDs visualize the switching states of the optocouplers. The connection wiring is made via two 8-pole plug-in screw terminals.
- 8 optocoupler inputs: 15V – 30V (optional 5V – 15V) AC / DC
- Galvanic isolation of the inputs: max. 2500V
- 16 bit counter per channel (up to 100Hz)
- Filter for counter / flipflops adjustable from 5ms to 255ms
With our optocoupler inputs, digital signal states can be recorded within a voltage range of 5V to 30V AC or DC. Input and output circuits are galvanically isolated from each other up to 2.5kV.
Digital In Input Filter [New feature since Q4/2020!]
With our Digital-In modules, an input filter can be set in a time interval of 1ms…255ms to filter interference pulses.
This means that AC signals can also be detected cleanly.
Each input has a 16 bit counter that can count up to 65535 pulses. If the maximum counter value is exceeded, the counting process starts again from zero. By means of a software command, the current status of all input counters can be written simultaneously into a separate memory area.
Recording of status changes
Status changes that occur between the readout cycles are reliably detected by internal flip-flops and can be read out separately by software. In addition, such an event is signalled by a status LED. Resetting is done automatically after the flip-flops have been read out.
Each digital input and output has a separate LED that lights up when the signal state is active. Furthermore, the status of the operating voltage, the communication with the interface, error events or the occurrence of a timeout can be displayed.
