24-Channel I/O Card (FloBoss 500-Series)
 |
- 8 Analog Inputs – AI.
- 2 Analog Outputs – AO.
- 2 Pulse Inputs – PI.
- 2 Discrete Inputs – DI.
- 2 Relay Discrete Outputs – DO.
- 8 Selectable Discrete Inputs/Discrete Outputs.
The parameters of the I/O channels are configured using ROCLINK™ for Windows Configuration Software. Refer to Specification Sheet 4:RLFW.
The I/O card uses a microprocessor for monitoring, controlling, and acquiring data from external devices connected to the I/O channels, as well as for relaying the information to and from the main processor card. The I/O channels have removable plug-in terminal blocks for field wiring. Sockets for AI scaling resistors are provided on the back of the I/O card, along with switches for the selectable DI/DO channels.
The I/O card receives its power from the main processor card. The processor is isolated from noisy I/O circuits by optical coupling and a DC/DC power converter, which supplies power for most of the I/O circuits. External 24-volt loop power can be connected for the Analog Input circuits; otherwise, 12-volt loop power is supplied by the DC/DC converter.
