Yokogawa Duplexed Safety Control Unit SSC60D-F2521
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-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-F2521
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 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.
Number of I/O Modules Mounted
Up to eight for each safety control unit
Up to 110
for each SCS (using SEC402 ESB bus coupler module and CFS1350 Node Expansion
Package)
Up to 78 for each SCS (using SEC401 ESB bus
coupler module)
