For Class-1 safety requirements, the normal pin distance governed by an 8-way DIL socket is adequate.Analog Devices is in the process of updating our website. This device boasting a breakdown voltage specification of 5,300 V, it is Class-2 compliant provided the distance between the pins is greater than 6 mm. Good results were obtained with, among others, the Siemens CNY17-2. In general, the lower the value, the less sensitive the interface will become.Īlmost any opto-isolator device may be used provided its transfer is close to 100% (or ‘1’ - check datasheets). The circuit may be modified for compatibility with 4/20 mA industrial current-loop systems by carefully matching the value of R2 to the opto-isolator used. This resistor will typically be between 330 Ω and 1 kΩ, and the LED current should always be kept well below 50 mA to prevent damage to the opto-isolator.

If voltage drive is used instead of 0/20 mA pure current drive, a current limiting resistor is required at the opto-isolator input. Notes: This item is new as shown in an open box. Resistor R2 speeds up turn-off time.ĭiode D7 has been included to protect the optoisolator against excessive reverse voltages - these may occur when the interface is accidentally wired back to front. Opto-isolator devices normally switch on reasonably fast but are relatively slow to switch off. The positive and negative supply rails for IC1 are set up by rectifying the unused RS232 potentials via diodes D1 through D6, with C1 and C2 acting as reservoir capacitors. The standard RS232 connector is a 9-way male ‘D’ type whose connections are shown in the table. They provide 2kV of isolation to protect your equipment as well as a variety of connector options. This is achieved by stealing power from unused RS232 signal lines. The RS-232 optical isolators are ideally suited for many applications from control panel installations requiring DIN Rail mounting to in-line or bump in the cable installations found in laboratory or retail systems.
