Yokogawa Duplexed Safety Control Unit SSC60D-S2541

HARDWARE SPECIFICATIONS

For the criteria for the installation environment, refer to “ProSafe-RS Safety Instrumented System Overview” (GS 32Q01B10-31E).

Processor

MIPS R5000 Processor

Main Memory Capacity

128 MB

Memory Protection at Power Failure

Application program is stored in non-volatile memories.

Processor Module Management Information is stored in the storage memories backed up by a non- rechargeable battery. 

The battery’s recommended replacement cycle is three years when it is used under the average ambient temperature of 30 °C or less.

Temperature Adaptability

A fan unit is provided for high temperature use where the safety control units (SSC60S-F/SSC60D-S2541-F) ambient temperature exceeds 40 °C.

Communications Interface

Vnet/IP interface: Dual-redundant

ESB bus interface: Dual-redundant

Communication on Vnet/IP

Yokogawa Duplexed Safety Control Unit SSC60D-S2541

Communication speed:   100 Mbps, Full duplex

Connection:    UTP cable (CAT5e or higher), RJ45 connector

Interface:   100 Base-TX compliance

Max. distance: 100 m (distance between SSC60S/ SSC60D-S2541 and Layer 2 switch)

Connecting Safety Node Units

Up to 13 safety node units can be connected to a safety control unit using SEC402 ESB bus coupler module and adding CFS1350 Node Expansion Package.

Up to 9 safety node units can be connected to a safety control unit using SEC401 ESB bus coupler module.

For installation, ESB bus coupler modules (SEC402/ SEC401) should be mounted on 7-th and 8-th slots.

ESB bus can be extended by Optical ESB bus repeater modules.
