Diamond Systems Opal-MM-1616 - Opto In + Relay Out PC/104 Module

16 Channel Optoisolated Inputs & 16 Relay Outputs

Introduction

Opal-MM-1616 is a PC/104 format digital I/O module designed for industrial applications requiring isolation between the computer and the external signals it is monitoring and controlling.

The Opal-MM-1616 features 16 optoisolated digital inputs and 16 relay outputs. Each input has an input range of 0-30VDC. Opal-MM-1616 can be configured to generate an interrupt when any input changes state. Either or both banks of 8 inputs can be configured for interrupt operation. One 34-pin I/O header is used for the optoisolated inputs. The 16 relay outputs are SPDT format (form C). Each relay has 3 contacts: Common, Normally Open, and Normally Closed. For safety and reliability, all relays are at their power-off state at power-up or system reset. Each relay can switch both AC and DC voltages. Two 26-pin I/O headers are used for the relay outputs with 8 relays on each pin header. The relays have long lifetime (10,000,000 operations) and quick actuation time (5ms max operate and release, break before make). Diamond Systems' Universal Driver software provides drivers and example code for use with the Opal-MM-1616. The software provides support for interrupts and enables you to integrate you own code that is called when an interrupt occurs.

Signal Isolation

Opal-MM-1616 provides isolation on its input and output lines. The board will withstand up to 500V DC or AC difference in potential between the I/O lines and the rest of the board's circuitry. Each input and output channel on Opal-MM-1616 is completely independent and does not share any signal trace with any other channel. Therefore, every channel is isolated from every other channel.
