Timing/Control State Machine

Product Specifications

Technical details and manufacturing context for Timing/Control State Machine

Definition

A Timing/Control State Machine is a fundamental component of Control Logic systems that manages the sequence of operations, timing relationships, and state transitions in automated equipment. It operates by transitioning between predefined states based on input conditions and timing signals, ensuring coordinated execution of control functions. This component is typically implemented as a digital integrated circuit, often housed in a plastic-encapsulated package with semiconductor silicon as the core material and copper for electrical interconnections. It is designed for integration into machinery and equipment manufacturing applications, where precise timing and control sequencing are critical. The state machine operates within specified electrical and environmental parameters, including an operating voltage of 24 V DC ±10% per IEC 61131-2, power consumption ranging from 5 to 15 W, and a listed operating temperature range of -40 to 85 °C that must be confirmed for the specific device. IEC 60068-2-1 and IEC 60068-2-2 are cold and dry-heat test methods and do not establish this range. It supports a clock frequency of 1 to 100 MHz, with state transition times between 10 and 100 ns. The device offers 16 to 256 programmable states, with memory sizes from 64 to 512 KB for storing state definitions and sequence programs. Output current per channel is 10 to 500 mA, derated at high temperatures, and the device provides ingress protection ratings from IP54 to IP65 per IEC 60529. Physical dimensions are typically 100×60×25 mm, with a weight of 150 to 300 g. The state machine is designed for DIN-rail mounting, though custom sizes may be available. It is important to verify model-specific values and standards with the legal manufacturer or supplier before procurement, as the listed ranges are reference values and may vary by model and application.

Working Principle

The state machine operates through a finite set of states, with transitions between states triggered by specific input conditions, timing signals, or events. It typically includes a state register to store the current state, combinational logic to determine the next state based on inputs, and output logic to generate control signals. Clock signals synchronize state transitions to maintain precise timing relationships. The device uses a clock frequency of 1 to 100 MHz, and the propagation delay from clock edge to output change is 10 to 100 ns. The number of states is programmable from 16 to 256, and the memory size of 64 to 512 KB holds the state definitions and sequence program. The state machine operates within a voltage range of 24 V DC ±10% and consumes 5 to 15 W depending on the number of active outputs. It is designed for an operating temperature range of -40 to 85 °C and storage temperature of -40 to 105 °C, with non-condensing humidity of 5 to 95% RH. The device provides output current per channel of 10 to 500 mA, derated at high temperatures, and has an ingress protection rating of IP54 to IP65. These parameters ensure reliable operation in industrial environments, but actual performance must be verified for the specific model and application.

Frequently Asked Questions

What is the operating voltage range for this state machine?

The operating voltage is 24 V DC ±10% per IEC 61131-2. Outside this range, logic states may be undefined. Always verify the exact voltage requirements for your specific model.

What are the temperature limits for operation and storage?

The listed operating temperature range is -40 to 85 °C and the listed storage temperature range is -40 to 105 °C; both must be confirmed for the specific device. IEC 60068-2-1 and IEC 60068-2-2 are cold and dry-heat test methods and do not establish these ranges. Exceeding manufacturer-confirmed limits may degrade timing accuracy or cause damage.

How many states can be programmed?

The number of states is programmable from 16 to 256. More states require more memory, with memory sizes ranging from 64 to 512 KB. Confirm the memory capacity for your application.

What is the ingress protection rating?

The ingress protection rating is IP54 to IP65 per IEC 60529. Higher IP ratings are suitable for dusty or wet environments. Verify the rating for your specific model.
