INTRODUCTION

The DLP-IO20 Data Acquisition Module is a low-cost, easy-to-use data acquisition system for analyzing AC voltages, driving 5 volt relays, controlling and monitoring processes, and measuring DC voltages in the range of 0-5 volts. This module provides top side wire terminal blocks for the wiring connections.

The 20 channels on the DLP-IO20 are broken down as follows 3 outputs with high current relay/LED drivers, and 17 Digital I/O, 14 of which can be set to analog input mode. The DLP-IO20 also provides 2 latching relay contacts. Each of the channels and relay contacts can be controlled via simple multibyte commands. All operational power is taken from the host PC via the USB port.

The mode of each I/O is automatically changed with each command sent. For example, if an I/O is set to Digital Output High and then the Digital Input Mode is selected, the I/O is first changed to Input Mode and then the high/low state is read and returned to the host.

SPECIFICATIONS

The DLP-IO20 is an all 5-volt system that derives its power from the host USB port. Channels have the following capabilities:

DLP Design, Inc.

Relay Contacts There are 2 sets of relay contacts on the board. These contacts are latching, and are capable of handling resistive loads of up to 4A 30 VDC, 0.6A 110 VDC, and 1 A 125 VAC. Each of the two on-board relays has two sets of SPDT contacts that have been connected in parallel to increase the current carrying capability. These are detailed in section 6 under the table describing K1 and K2.

Relay Drivers There are 3 relay driver outputs on the board. These outputs connect to one side of a 5V relay coil, the side of the coil is connected to the +5V terminal.

Analog In 14 inputs can read and return the voltage on the Analog inputs using a 10-bit ADC. The maximum sample rate is 20Ksps. The input voltage range is 0 to 5 Volts. Refer to section 7 of this document for more details.

Digital Output Set high, or clear low, configurable as digital outputs 5V . The actual high/low voltage depends upon sink/source current.

Digital Input Read the inputs high/low state.

ABSOLUTE MAXIMUM RATINGS

Stresses above those listed here may cause permanent damage to the DLP-IO20:

Operating Temperature 0-70°C

Voltage on Digital Inputs with Respect to Ground -0.3V to +5.3V

Voltage on Analog Inputs with Respect to Ground -0.3V to +5.3V

Voltage on Relay Contacts with Respect to Ground/Return 110VDC, 125VAC

Sink/Source Current on Any I/O 25mA

Sink/Source Current on all I/O combined 90mA

WARNINGS
• Unplug from the host PC before connecting to the I/O terminals on the DLP-IO20.
• Isolate the bottom of the board from all conductive surfaces.
• Observe static precautions to prevent damage to the DLP-IO20 module.
