Honeywell 10105/2/1

Product Features

Honeywell 10105/2/1 input stage of the module adopts a “fail-safe” design, whereby a component failure causes the input signals received by the processor to be in a safe state (e.g., a preset safe value in the event of a signal interruption) in compliance with industrial safety standards.

Honeywell 10105/2/1 integrates 16 analog input channels, which is suitable for scenarios requiring a large number of analog signal acquisition and saves rack space.

Honeywell 10105/2/1 performs self-tests on signal acquisition accuracy, inter-channel crosstalk, internal power supply, etc. to ensure signal reliability during the configured process safety time.

Honeywell 10105/2/1 provides galvanic isolation between the input channels and internal 5 Vdc and 24 Vdc circuits to minimize interference and improve signal stability.

Honeywell 10105/2/1 is adapted to the I/O back-planes and central components of the FSC system, and supports interoperability with other modules in the system.

Product Using Principle

Honeywell 10105/2/1 receives analog signals (e.g. current or voltage signals from sensors) from field devices, and converts the analog signals to digital signals through the internal conversion circuit.

Honeywell 10105/2/1 has a built-in self-test circuit that monitors the channel status, power supply voltage and signal accuracy in real time. If a fault is detected (e.g., component failure, signal abnormality), it immediately switches the output signal to the preset safety state.

Honeywell 10105/2/1 interacts with the central processing unit (CPU) and communication module (COM) of the FSC system through horizontal buses (e.g. 1-BUS, 2-BUS), and transmits the collected signals to the system for further processing.

The internal logic circuits of are powered by 5 Vdc and the signal acquisition circuits are powered by 24 Vdc, which are isolated by galvanic isolation to avoid interference affecting the signal accuracy.

Product Applications

High-safety industrial scenarios:

Honeywell 10105/2/1 Fail-safe High-density Analog Input Module is suitable for chemical, petroleum, natural gas and other process control fields with high safety requirements, for the acquisition of key analog parameters such as pressure, temperature, flow rate, etc., as a signal input unit for the safety instrumented system (SIS).

High-density signal acquisition:

Thanks to its 16-channel support, Fail-safe High-density Analog Input Module is suitable for centralized acquisition of multiple analog signals, e.g. for distributed sensor signal aggregation in large production plants.

Fail-safe scenarios:

Honeywell 10105/2/1 Fail-safe High-density Analog Input Module complies with safety standards such as DIN V 19250 and can be used in safety applications up to and including safety class AK 8 to ensure reliable signal acquisition in the event of process anomalies.
