SIL2 TUV Certified-Safety Controller:TK-E50
Features
Safety RTU serves as the logic solver in a Safety Instrumented System (SIS) acc. to IEC 61511, it controls complex and often critical processes in real time - executing application programs that receiving field sensor signals, performing calculations for continuous process control and generating control signals to actuator.
Features
The main features of TK-E50 Safety RTU are as follows:
l Facilitates differing fault tolerant topologies - 1oo1 or 1oo2
l Flexible modular construction using individual modules to build a system
l Operates as a standalone system or part of a larger distributed network
l IEC 61508 certified, reviewed and approved by TÜV Rheinland
l Scalable I/O module expansion
l I/O module replacement without system interruption for dual-redundant configuration
l Supports industry standard safety communication protocol of ESCB
Non-safety features of TK-E50 Safety RTU:
l Connection with HMI Software via Ethernet connection using standard Modbus TCP protocol.
l Connect to third-party I/O devices via RS-485 serial connection using standard Modbus RTU protocol and act as Modbus master.
Expansion Capability
TK-E50 system is comprised of safety engineer station and safety control station.
l Safety Engineer Station (SES)
SES is personal computer in which two software tools: FlexiSafe Workbench and TK-ESet, are installed. They are used by engineers to develop application programs and configure the system
l Safety Control Station (SCS)
SCS is the controller which is comprised of a Safety Processing Unit (SPU) and a Safety Extension Unit (SEU). SPU is the basic unit of SCS. SEU is optional for SCS and is used to increase the number of I/O channels.
A SPU supports up to 96 I/O points and a SEU supports up to 128 I/O points (including DI, AI and DO_8 in total). The total I/O point number for a SCS is 480 maximum.
