Technical Specifications
The Siemens C98043-A1601-L1 serves as a DC speed controller board for industrial motor drive applications. This board measures 160 mm in height, 100 mm in width, and 25 mm in depth for compact cabinet mounting. It weighs approximately 0.5 kilograms, which enables easy handling during installation or replacement.
The unit draws 0.8 A from a 24 V DC power supply, consuming roughly 19.2 W under normal operating conditions. It features one analog input for speed reference signals between 0 and 10 V. The board also includes one tachometer feedback input for closed-loop speed control. It provides two digital outputs for contactor and brake control functions.
Hardware Overview
The board contains 64 KB of firmware memory for control algorithm storage. It also includes 16 KB of RAM for real-time operational parameter handling. The unit offers a speed control range from 0 to 200% of base motor speed. It delivers a regulation accuracy of ±0.1% of maximum speed under stable load conditions.
The controller implements PID algorithm for smooth acceleration and deceleration profiles. It provides an adjustable current limit from 50% to 150% of rated output. The operating temperature range spans 0°C to 50°C for typical industrial environments. Storage temperatures extend from -25°C to 70°C without causing component damage. Humidity tolerance covers 10% to 90% non-condensing conditions for reliable performance.

Control Features and System Integration
This speed controller board accepts 0 to 10 V analog signals for speed command inputs. It uses tachometer feedback to achieve precise closed-loop regulation. The Siemens C98043-A1601-L1 implements a PID algorithm with proportional, integral, and derivative gains. It provides adjustable ramp times for smooth acceleration and deceleration profiles. The board generates a 4 kHz PWM signal for power device triggering. It includes an adjustable current limit to protect the motor from overload conditions. The unit offers two selectable control modes: speed control and torque control. It provides a built-in potentiometer for manual speed setpoint adjustments during commissioning. The board features opto-isolated digital inputs for start, stop, and reset commands. It includes relay outputs for fault indication and external alarm signaling.
Installation and Reliability Data
The C98043-A1601-L1 mounts onto a standard DIN rail using integrated clips. It requires 30 mm clearance above and below for adequate airflow around components. The board consumes only 19.2 W, which allows passive cooling without fans. It delivers a mean time between failures of 250,000 hours for long-term dependability. The unit carries CE marking for European market deployment. It passes vibration testing at 10 to 55 Hz with 0.15 mm amplitude. The module withstands shock loads up to 5 g for 30 ms duration without degradation. Event logs store in dedicated EEPROM memory for diagnostic troubleshooting. Firmware updates occur via a serial programming interface. The board contains approximately 120 discrete components on a single-sided PCB.
