The OP4250-1 features 32 optically isolated input channels. All are sampled simultaneously for additional simulation accuracy. It is perfectly suited to interface real-life environment signals to TTL or differential levels for RT-LAB simulator, providing perfect electrical isolation and discharge protection.
- 32 optically isolated input
- All inputs are sampled simultaneously, at up to 1 Mb/s
- Inputs are read in parallel for any size bus
- Choice of sink or source inputs connection (anode and cathode side available).
- Minimum current input of 3.6 mA
- 5V to 30V input voltage
- 30V maximum reverse
The optically isolated inputs accept a wide input voltage range, from 5 to 30 Volts, according to user requirements. They have a low threshold current; typically 3.6 mA.
Each input has reverse voltage protection of up to 30 Volts provided by a Schottky diode.
When current flows from Din + to Din -, the output of optocoupler A is low and the Din_FPGA signal is low.
When no current flows, the optocoupler output A is high and the Din_FPGA signal is high.
The signal conditioning module inputs have both anode and cathode sides available to the user (on the I/O connector).
The diagrams below illustrate typical application examples.
