Description

The PDISO-8 is a low-cost 8-channel isolated input/output interface board designed for control and sensing applications. The PDISO-8 provides eight electromechanical relay outputs and eight optically isolated inputs, so you can both load (send) and sense signals. The PDISO-8 can be used in various applications including load switching, external-switch sensing, contact closure, and external-voltage sensing. This interface board is easily installed in any ISA-bus compatible computer.

The eight electromechanical relay outputs (contact closures) are addressed as a single I/O byte. Five of the relays are Form C contacts (SPDT) and three are Form A (SPST–normally open). The relay contacts are rated at 3A at 125V rms with a resistive load. The state of the relays (On/Off) can be determined by reading back the data from the I/O port.

The eight individual optically isolated inputs can be read as a single I/O port byte. The inputs are not polarity sensitive and can be driven from DC or AC (50–1,000Hz) control voltages from 5 to 24V rms. Each input includes a switchable slow/fast filter with a time constant of 5ms. The filter must be selected for AC input voltages but can be switched out to obtain response times of less than 50µs for DC inputs. Additional resistance can be added to the PDISO-8 inputs externally to extend the input voltage range. The inputs can be mixed between AC and DC. The inputs can be driven from standard 12/24VAC control transformers.
