1.

Before Using the Product

This chapter provides information you should know before using the product.

About the Product

This product is an USB2.0-compliant digital I/O unit that provides the input and output function of

digital signal from the USB port of PC. Digital signals can be input and output at 12 - 24VDC.

16 channels of Optocoupler isolated inputs (compatible with both current sink and current source

outputs) and 16 channels of Optocoupler isolated open-collector outputs (compatible with current sink

type) are equipped. Up to eight channels are used as an interrupt. Also, including a digital filter function

which prevents wrong recognition of input signals, and output transistor protection circuit (surge

voltage protection and over current protection).

Compact design not restricting installation location (188.0(W) x 78.0(D) × 30.5(H)) makes it easy to

install the product within the panel or device using DIN rail mounting jigs, or on the floor or wall.

Features

- 16 channels of Optocoupler isolated inputs (compatible with current sink and current source outputs)

and 16 channels of Optocoupler isolated open-collector outputs (compatible with current sink type).

This product has the 16 channels of Optocoupler isolated inputs (compatible with current sink and

current source outputs) and 16 channels of Optocoupler isolated open-collector outputs (current sink

type) whose response speed is 200μsec.

Common terminal provided per 8 channels, capable of supporting a different external power supply.

Supporting driver voltages of 12 - 24 VDC for I/O. The digital input can be checked with the LED

indicator.

- Optocoupler bus isolation

As the USB (PC) is isolated from the input and output interfaces by Optocouplers, this product has

excellent noise performance.

- 8 input signals as interrupt request signals.

You can use up to 8 input signals as interrupt request signals and also disable or enable the interrupt in

bit units and select the edge of the input signals, at which to generate an interrupt.

- With a digital filter to prevent wrong recognition of input signals from carrying noise or a chattering.

This product has a digital filter to prevent wrong recognition of input signals from carrying noise or a

chattering. All input terminals can be added a digital filter, and the setting can be performed by

software.

- Output circuits include Zener diodes for surge voltage protection and circuits for overcurrent

protection.

Zener diodes are connected to the output circuits to protect against surge voltages. Similarly, Over-

current protection circuits are fitted to each group of 8channels outputs.

The output rating is max. 60VDC, 100mA per channel

DIO-1616LN-USB

- Operation with USB bus power/12 - 24VDC power supply

As the product can operate with USB bus power, power supply from the external source is unnecessary.

Operation with a wide range power supply of 12 - 24 VDC is also available when the product is used

such as with a laptop computer to save power consumption or when the environment requiring a

separate power supply, such as using a non-power connected USB hub.

Therefore, it can be used in various equipment configuration and power supply environment. In

addition, the FG terminal is equipped in the power connector.

- Compact design not restricting installation location (188.0(W) x 78.0(D) x 30.5(H))

Compact design of 188.0(W) × 78.0(D) × 30.5(H) does not require special installation location.

- Compatible to USB1.1/USB2.0

Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at HighSpeed (480 Mbps).

- Diverse installations such as screw fastening, magnet (optional purchase), DIN rail are possible.

Installation on the floor / wall /ceiling is possible by screw fastening, with magnets (optional purchase),

rubber feet, etc.

In addition, DIN rail mounting mechanism is equipped as standard with the product, making it easy to

install the product within the panel or the device.

- Easy-to-wire terminal connector adopted

Adoption of terminal connector (with screws) enables to achieve easy wiring.

- Windows compatible driver libraries are attached.

Using the attached digital I/O driver API-DIO(WDM) makes it possible to create applications of

Windows. In addition, a diagnostic program by which the operations of hardware can be checked is

provided.
