OP5251 User Manual — Opal-RT Technologies 4 INTRODUCTION Circuit Layout Diagrams INTRODUCTION The OP5251 is a part of the OP5000 series of optional, versatile signal conditioning modules for OpalRT’s state of the art HIL (hardware-in-the-loop) systems. Designed for Opal-RT’s simulation systems, the OP5251 provides digital input and output signals with specific voltage conditioning. The optical isolation of the OP5251 I/Os make it ideal for environments where voltage isolation is required. DESCRIPTION The OP5251 features 32 optically isolated input channels and 32 optically isolated output channels. All of these I/Os are sampled simultaneously for additional simulation accuracy. It is perfectly suited to interface real life environment signals to TTL or Differential for RT-LAB simulator, providing perfect electrical isolation and full short-circuit or discharge protection.

The board is easily inserted onto the OP5251, over the connectors RN13, RN14, RN15, RN1, RN2, RN9 and PWR1. Consult the “Pin Assignments” table for details on pin connections and channels for the RS-422 cable. Figure 2: RS-422 Communication Module PCB Diagram ! CAUTION Do not bend the pins when inserting or removing the RS-422 Communication Module into the OP5251. INTERFACES Inputs The optically isolated inputs accept a wide range of input voltage, ranging from 4 to 30 Volts, according to user’s requirements. They have a low threshold current; typically 6 mA within the 5 to 15 mA range. The inputs are current limited by the interchangeable resistor array mounted on sockets. The resistor value may be changed by the user to enable higher input voltage. By default, the module comes equipped with the resistor value set to 680 Ohms, which is recommended for 5 to 12 Volts input. Each input has a reverse voltage protection of 5 Volts or more provided by a diode.
