The Sealevel Systems’ ISO-16 provides 16 optically isolated inputs for connection to devices including push buttons, switches and other user inputs. For your reference, we have provided a sample wiring diagram for an optically isolated input circuit.

The standard input resistor value is 560 Ohms, minimum turn-on voltage is 2.8V, maximum input voltage is 12V and maximum current is 20mA. If your application requires other values, please refer to the user manual or contact a Sealevel support specialist.

The REL-16 provides 16 Reed relay outputs for controlling devices via on/off closures. Simply write to the address corresponding to the relay to change the state from open to closed. All relays power up in an open state. For your reference, we have provided a sample wiring diagram for a reed relay output circuit.

Our SeaI/O Family of Windows 98/ME/NT/2000/XP and Linux Software drivers is included along with sample applications and utilities for rapid application development.
