10-Channel I/O Card (FloBoss 500-Series)
 |
- Discrete Inputs (DI).
- Pulse Inputs / Discrete Inputs (PI)/(DI).
- Analog Inputs (AI).
- Discrete Outputs (DO).
- Analog Output (AO).
The characteristics (called parameters) of the I/O channels are configured using ROCLINK™ for Windows Configuration Software.
Refer to Specification Sheet 4:RLFW. Light-emitting diodes (LEDs) provide a visual indication as to the state of the Discrete Inputs, Pulse Inputs, and Discrete Outputs.
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 Master Controller Unit (MCU). Each I/O channel has a removable plug-in terminal, used for field wiring.
The I/O card receives power for its processor and logic circuits from the main processor card. The I/O card has a DC/DC converter (with a jumperselectable “+T” output of 12 or 24 volts) to supply power for its field I/O circuits. This converter helps isolate the field I/O from the processor.
The power converter produces enough current to supply four current loops (three AIs and one AO). It also provides the power to run the Analog-to-Digital (A/D) converters, Digital-to-Analog (D/A) converters, and the Discrete Inputs. The power converter can turn off under processor control to reduce the load in low battery conditions.
