PISO-725 CR

Industrial PCI Card with 8-ch isolated digital input and 8-ch relay output.

The PISO-725 is a 16-channel digital input/output interface board for PCI bus computers. It can be installed in a 5 V PCI slot and supports true "Plug & Play" to automatically obtain I/O resources. The PISO-725 has a single DB-37 connector, and provides 8 electromechanical relay outputs and 8 isolated/non-isolated digital inputs. The digital inputs can be set to either isolated or non-isolated via a hardware jumper. Each of the digital inputs will generate an interrupt signal if the state is changed, which is very useful when monitoring for contact closures/openings as it is not necessary to continuously poll the inputs.

The isolated DI channels use a short optical transmission path to transfer an electronic signal between elements of a circuit and keep them electrically isolated. With 3750 Vrms isolation protection, these DI channels allow the input signals to be completely floated so as to prevent ground loops and isolate the host computer from damaging voltages. Relays are used where it is necessary to control a circuit using a low-power signal (with complete electrical isolation between the control and controlled circuits), or where several circuits must be controlled by one signal. All relays are de-energized (off) while powering-on, and support On/Off status read back. The PISO-725 can be used in various applications, including contact closure, external voltage sensing, load sensing and I/O control.
