1753 GuardPLC Safety I/O
The GuardPLC system was designed in accordance with IEC 61131, the worldwide standard for programmable controls. It complies with many of the latest global safety standards and is certified by TÜV Rheinland in accordance with IEC 61508, the worldwide standard for functional safety in programmable electronic systems. GuardPLC can be used without restriction in applications up to Category 4 according to EN-954 and Safety Integrity Level 3 (SIL 3) according to IEC 61508.
The GuardPLC system consists of four main components:
- Packaged or modular controller and associated integrated I/O
- distributed I/O modules
- GuardPLC Ethernet, a safe Ethernet communications network
- programming and configuration software
GuardPLC 1600
GuardPLC 1600 is a mainstream, cost-effective safety PLC offering a built-in 4 port Ethernet switch and digital I/O (20 safety rated inputs and 8 Category 4 outputs). 100M GuardPLC Ethernet comes standard, plus the GuardPLC 1600 offers additional communication options for flexibility in connecting to HMI devices and standard PLCs. At 10 ms throughput, the GuardPLC 1600 is the fastest safety PLC in the industry. Its exceptionally high mean time between failures ensures your system is not only safe but also reliable. Removable terminal blocks make swapping controllers a quick task so operations can be up and running again quickly in the event of failure.
GuardPLC 1800
GuardPLC 1800 takes all the features of the GuardPLC 1600, then adds analog inputs and high speed counters for specialized applications such as emergency shut down, flame control, and amusement park ride control. Its eight safety rated analog inputs and two safety rated high speed counters allow the GuardPLC 1800 to expand beyond digital safety devices and sense field temperatures, pressure, speed, and motion. Like the GuardPLC 1600, 100M GuardPLC Ethernet comes standard, plus the GuardPLC 1800 offers additional communication options for flexibility in connecting to HMI devices and standard PLCs.
