 T8442 ICS Triplex Trusted TMR Speed Monitor Module The Trusted Speed ​​Monitor Input Field Termination Assembly (SIFTA) is a DIN rail assembly. When part of the T8442 Triple Modular Redundant (TMR) Speed ​​Monitor system, it provides the input field interface for three rotating units. It provides all necessary input interfaces for the Trusted T8442 TMR Speed ​​Monitor. Nine speed input channels, arranged in three groups of three inputs each. Separate field power inputs are provided for each of the three speed input groups. Field power and signal isolation between input groups. Versatile input connections allow linking with active speed sensors with totem pole outputs, active speed sensors with open collector outputs, passive magnetic inductive speed sensors.The T8846 Speed ​​Input Field Termination Assembly (SIFTA) is an integral part of the complete T8442 Speed ​​Monitor system. It is DIN rail mounted and contains passive signal conditioning, power distribution and protection components. When installed in a Trusted system, one T8846 SIFTA is required for each T8442 speed monitoring module hot-swap pair. The SIFTA has nine identical speed sensor signal conditioning circuits arranged in three groups of three. Each of the three groups is a galvanically isolated entity with its own field power supply and I/O signal interface. For SIL 3 applications, multiple sensors must be used. The ICS Triplex system is centered around safety and fault tolerance. Critical components of the system, such as the processor and communication modules, are equipped with redundancy to ensure high availability and system uptime.Frequently asked questions about the product are as follows: -What is T8442 ICS Triplex? T8442 is a TMR (Triple Modular Redundancy) analog output module produced by ICS Triplex. -What are the output signal types of T8442? It can provide two types of 4-20mA current output and 0-10V voltage output. -What is the load capacity? For current output, the maximum load resistance is 750Ω. For voltage output, the minimum load resistance is 1kΩ. -How to perform daily maintenance? Check the working status of the module at a certain time and observe whether the indicator light is on. Clean the dust on the surface of the module to prevent dust accumulation from affecting heat dissipation.
