SCP451 YOKOGAWA SCP451-11 SSC50DStyle S1 Processor Module

SCP451 YOKOGAWA SCP451-11 Style S1 Processor Module

 GENERAL This GS provides the hardware specifications of the safety control unit for Vnet/IP, which are intelligent parts of the safety control station (SCS).  HARDWARE SPECIFICATIONS For the criteria for the installation environment, refer to “ProSafe-RS Safety Instrumented System Overview (for Vnet/IP)” (GS 32P01B10-01EN). l Processor MIPS R5000 Processor l Main Memory Capacity 32 MB l Memory Protection at Power Failure Application program is stored in flash memory. 

Processor Module operation data is stored in NVRAM (nonvolatile memory). l Temperature Adaptability A fan unit is provided for high temperature use where the safety control units (SSC50S-F/SSC50D-F) ambient temperature exceeds 40 °C. l Communications Interface Vnet/IP interface: Dual-redundant ESB bus interface: Dual-redundant l Communication on Vnet/IP Communication speed: 100 Mbps, Full duplex Connection: UTP cable (CAT5e or higher),RJ45 connector Interface: 100BASE-TX compliance Max. distance: 100 m (distance between SSC50S/SSC50D and Layer 2 switch) l Connecting Safety Node Units For each safety control unit, up to nine safety node units can be connected. For installation, ESB bus coupler modules (SEC401) should be mounted on 7-th and 8-th slots. ESB bus can be extended by Optical ESB bus repeater module. l Number of I/O Modules Mounted Up to eight for each safety control unit Up to 78 for each SCS l Power Requirements Specify suffix codes. Voltage: 100 to 120 V AC, 50 or 60 Hz Voltage: 220 to 240 V AC, 50 or 60 Hz Voltage: 24 V DC l Power Consumption
