ACLD-9182A/B
16-CH Opto-Isolated Digital Input Termination Board
Isolation and Dry Contact / Non Polarized Opto Isolated !!


Description

The ACLD-9182A/B opto-isolated D/I termination board provides 16 optically isolated digital inputs for use with any ACL series I/O board with D/I channels on 20-pin flat ribbon connectors.

Optical isolation provides a good solution in the prevention of floating potential and ground loop problems.

Each input channel has a red LED to reflect the input status. If the input voltage is high, the LED will light, otherwise the LED is off. Each input channel is jumper selectable to be either AC-filter or non-AC-filter.

Non-Polarized, Opto-Isolated Digital Input (ACLD-9128B only). The digital input is first routed through a photocoupler (PC-814), so that the connections are not polarity sensitive whether used on AC or DC voltage. Also, a single-pole filter with a time constant about 5ms is used to filter when the AC inputs pass through. The outstanding features of this circuitry are:
- Non polarity sensitive digital input
- Both DC or AC (50~1000 Hz) inputs
- Up to 1,000 V isolation coltage
- DC noise rejection (spikes or constant debouncing)
