XV303 CR ICP DAS Expansion Boards

• Multifunction (4 AO, 4 DI, 4 Relay)
• Individual Channel Configuration for Analog Output
• Jumper Selectable Voltage or Current Output
• Open Wire Detection for Current Output
• Configurable Power-on Value Settings
• 70 VDC Overvoltage Protection for Digital Input

INTRODUCTION

The XV303 is a multifunction expansion board that includes 4 Analog Output channels, 4 Digital Input channels and 4 Form A Relay Output channels. The Analog Output channels are 12-bit at +/-5 V, +/-10 V, 0 ~ +20 mA or +4 ~ +20 mA, and voltage and current outputs are jumper selectable. The XV303 also provides options for configuring power-on values for the Analog Output and Digital Output. 4 kV ESD protection and 2000 VDC intra-module isolation are also provided to enhance noise immunity capabilities in industrial environments.
