Product Overview

The Emerson SS6501T01 is a complete DeltaV SIS process safety system assembly.
It features the CHARMs Smart Logic Solver (CSLS) with Electronic Marshalling technology.
This assembly includes a CSLS Carrier, 2 CSLS units, and 2 Power Modules.
Two single Safety Network Ports for twisted copper and 2 Power Plugs are also included.
Each CSLS provides I/O processing and SIL 3-capable logic solving in one unit.
Consequently, the SS6501T01 reduces installed system cost significantly.
The modular architecture offers unprecedented flexibility for project needs.
Field mounted capable hardware allows I/O placement anywhere you need it.

System Capabilities

I/O and Channel Capacity

Each CSLS supports up to 96 local individually configurable channels .
These channels allow flexibility for implementing safety instrumented functions.
The Emerson SS6501T01 is designed for multi-core home run cables.
It also works with field junction box installation methods.
All communications are completely redundant from the channel to the CSLS.
Integrated HART I/O brings field diagnostics directly into the CSLS.

System Scalability

Number of CSLSs per SZ Controller reaches 16 units for local expansion.
Number of CSLSs per system reaches 1600 units for large facilities.
Therefore, the DeltaV SIS system scales from small to enormous applications.
I/O update rates equal 50 ms for responsive safety logic execution.

CSLS Carrier Specifications

Capacity and Configuration

The carrier supports one (simplex) or two (redundant) CSLS units.
It also supports one (simplex) or two (redundant) Power Modules.
Input power is redundant +24V DC ± 10% at 12.5 A maximum .
Output power to SIS CHARMs includes +6.3V DC at 4 A maximum .
For IS LS CHARMs, output is +24V DC ± 10% at 10 A maximum .
The SS6501T01 uses redundant Ethernet connections throughout.

Network Connectivity

Replaceable Safety Network Ports (SNP) provide Ethernet connections.
Copper twisted pair supports 10/100BASE-TX with RJ45 connectors .
Full duplex operation achieves 100 m distance for flexible placement.
Network addressing is auto-assigned during commissioning.

Mounting and Protection

The carrier mounts using a DIN rail latch to vertical orientated T-type rail.
Internal non-replaceable fuse provides overcurrent protection.
The Emerson SS6501T01 includes one or two slots on the CSLS Carrier.

CSLS and CSLS+ Specifications

Power Requirements

CSLS requires +24V DC ± 10% at 325 mA maximum for simplex operation.
For redundant CSLS, power requirement reaches 575 mA maximum .
CHARMs power consumption is additional to these values.
CSLS+ requires only 200 mA maximum for simplex operation.
Redundant CSLS+ draws 325 mA maximum from the supply.

Power Module Output

Power Modules require +24V DC ± 10% at 1.5 A maximum for simplex.
Redundant configuration draws the same 1.5 A maximum.
Output to LS-CHARMs is +6.3V DC ± 3% at 4 A maximum .

Heat Dissipation

Heat dissipation per carrier with redundant CSLS pair reaches 18 Watts maximum .
This includes 13 Watts for redundant CSLS (7 Watts for simplex).
For CSLS+, dissipation is 8.5 Watts for redundant (5 Watts for simplex).
Power Modules add 3 Watts for redundant configuration.
Each Safety Network Port adds 1 Watt to total dissipation.

LED Indicators

The Emerson SS6501T01 provides multiple LED status indicators.
Green Power LED indicates DC power is applied to the system.
Red Error LED illuminates when an error condition exists.
Green Active/Standby LED shows the operating mode of each CSLS.
Yellow Flashing Pri./Sec. CN LED indicates valid control network communication.

Installation Guidelines

First, mount the CSLS Carrier on a vertical orientated T-type DIN rail.
Secure the carrier using the DIN rail latch mechanism.
Insert the two CSLS units into the carrier slots carefully.
Install the two Power Modules into their designated positions.
Connect redundant +24V DC ± 10% power to both Power Modules.
Install the two Safety Network Ports for twisted copper connections.
Connect Ethernet cables to the RJ45 ports on each SNP.
For redundant configuration, connect both CSLS units to the network.
Verify all LEDs indicate normal operation after power-up.
Commission the system and confirm auto-addressing works correctly.

Wiring Recommendations

Use twisted shielded pair cables for all Ethernet connections.
Keep Ethernet cable runs under 100 m for reliable communication.
For power wiring, use cables rated for at least 12.5 A capacity.
Separate power and communication wiring by at least 150 mm.
Use home run cables from field devices to the CSLS Carrier.
For HART I/O, use standard instrumentation cables as specified.

Frequently Asked Questions (FAQ)

1. What safety integrity level does the SS6501T01 support?

The Emerson SS6501T01 provides SIL 3-capable logic solving. It meets IEC 61508 requirements for safety instrumented functions.

2. Can I add more CSLS units to this assembly?

The carrier supports either one or two CSLS units. For more channels, add additional SS6501T01 assemblies to your system.

3. What is Electronic Marshalling on this system?

Electronic Marshalling eliminates traditional marshalling cabinets. The Emerson SS6501T01 uses CHARMs for individual channel configuration.

4. Is the internal fuse replaceable in the field?

No, the internal fuse on the SS6501T01 is non-replaceable. A blown fuse requires returning the carrier for factory repair.

5. Can I mix CSLS and CSLS+ in the same carrier?

Yes, both CSLS and CSLS+ are compatible with the Emerson SS6501T01 . However, verify power requirements for your specific configuration.
