Individually-isolated digital inputs for up to three 16-bit groups
Polarity-protected input voltage amplitudes to 28V and 60V
60Vrms Isolation, Channel-to-Channel and Channel-to-Host PC
On-card shields prevent accidental contact with user voltages
Some models can generate interrupts when input bits change state.
Output connectors via on-card ribbon-cable headers
Lower cost per point than externally-racked solid-state relay modules
IDI-xx Series cards provide individual-input optical isolation and accept as many as 48 parallel, differential digital inputs at voltages up to 60 VDC. Protection circuits are included in case of accidental polarity reversal of input connections. These cards provide a much lower cost per point than externally-mounted, optically-isolated, solid-state modules or PLC's. Input connections are via ribbon-cable headers on the cards and a tie-down bar is included to provide strain relief for those cables. IDI-Series cards are especially useful in applications where high common mode external voltages are present as found in factory automation, energy management, security systems, and process monitoring applications. In addition to protecting your computer from accidental contact with high external voltages, this isolation eliminates troublesome ground loops.
