FC-RUSIO-3224 Honeywell Remote Universal Safe IO device

Description:

The RUSIO-3224 module has 32 universal safe IO channels with configurable channel function; configuration is done in Safety Builder. 
The RUSIO-3224 module can be used in applications up to SIL 3, in compliance with IEC 61508/61511.

It requires two RUSIO-3224 modules to achieve a redundant configuration.
All channels are powered out of the 24Vdc supply.
Each channel can be configured as:
• Digital input (with or without loop monitoring)
• Digital output (with loop monitoring)
• Analog input (0-20mA or 4-20mA active)
• Analog output (0-20mA or 4-20mA active)
The RUSIO-3224 module supports two (100Mbaud) ethernet links to communicate with a SM Controller.

The RUSIO-3224 module has a housing that is in line with the patented Series C design of Honeywell. It needs to be placed on an IO Termination Assembly (IOTA).

The RUSIO-3224 module has the following features:
• 32 universal IO channels that can be configured to control DI, AI, DO, AO
• any type of IO field signal has only to be connected to the two connections of the applicable universal channel on the IOTA
• proven-in-use redundant processor concept that complies with the SIL 3 safety requirements in single channel operation
• a dedicated communication link between these processors 
• a redundant communication link with the partner module (in redundant configuration)
• an Ethernet-based SM RIO link to the SM Controller in the network via dedicated switches; the SM RIO link uses a dedicated protocol
• monitoring the temperature of the electronics
• a configurable ESD function via channel 32 for dedicated safety related functions
• function-tested watchdogs that: monitor and/or handle:
- monitor cycle time and supply voltage
- handle the ESD function and memory errors
• LED indicators at the front of the module for power and health status indication
• real-time clock for Sequence Of Event (SOE) time stamping with a resolution of 1 msec
The RUSIO-3224 module functions as a universal IO module within the Safety Manager concept. It executes:
• the input scan of the process variables
• all functional tests of its hardware
• data exchange with its partner module
• data exchange via the SM RIO link with the SM Controller that executes the application logics
• update the outputs and thus the process

The FLASH nature of the memory allows for on line upgrading within the TUV-approved concept of both the system software as well as the channel configuration.
ESD function

The RUSIO-3224 module has one channel that can be configured as Emergency ShutDown (ESD) input; this is channel 32. To configure channel 32 as ESD input in Safety Builder, the two pins fork on the CN4 terminals on the IOTA must be in the ENABLE position (connecting pins 1 and 2).

Channel 32 must be configured for the ESD function in the software also, in order to execute the proper tests for the ESD channel.

When the (field) switch on the ESD input opens, the universal IO watchdogs switch off and all digital outputs of the connected RUSIO-3224 module(s) will go off and remain off. There is no software action required to do this; also there is no software action that can prevent this.

See detail A of Figure 251 on page 420 for a block diagram of this ESD input.
See detail B of Figure 251 on page 420 for the ESD input field connection.
The ESD input is line monitored (for short circuit in the field wires).
Place the (1kOhm) line termination resistor on (or near) the switch.
Frequently Asked Questions:

1.What kind of base does this FC-RUSIO-3224 model fit?

One RUSIO-3224 module can be placed on a non-redundant IOTA to establish 32 non-redundant channels
2.What is the voltage used for powering this module?

25V or less: use the derating curve in Figure 260

3.How to Removal of a RUSIO-3224 module?

Do these steps in the order given to remove the subject RUSIO-3224 module:
1. On the IOTA, set the applicable switch (POWER 1 or POWER 2) to OFF. The Power LED (green) must go off.
2. Completely loosen the locking screw.
3. Press both (removal) levers at the sides of the module down at the same time. See Active Position in Figure 262.
4. Remove the module from the IOTA.
5. Put the (removal) levers back in the upright (normal) position.
