Isolated 32 Digital Inputs/Outputs

Introduction

The ACL-7130 provides 32 isolated digital I/O and 32 TTL digital I/O channels. The isolated I/O channels are isolated to 2,500 Vrms (excluding cables), both channel-to-channel and channel-to-computer. It protects your computer against damage caused by accidental contact with high external voltage and eliminates troublesome ground loops.

Multiple interrupt sources can be selected by hardware jumper settings. Users can generate XT interrupt level (3, 4, 5, 6, 7) from CH0 and CH1 of both isolated or TTL digital inputs, or AT interrupt level (9, 10, 11, 12, 15) from internal timer pacer.
