PWM and Output Control
The SPC-SFMC-X2424A provides configurable high-side, high-/low-side, PWM, and H-Bridge outputs for direct control of proportional valves, solenoids, relays, and other electrical loads.
16 PWM Outputs with Current Feedback
Sixteen high-side channels can operate as digital or PWM outputs. Current feedback from 0.1–2 A allows the controller application to monitor the connected load.
Configurable PWM Control
PWM frequency can be configured from 10–2000 Hz, with an adjustable duty cycle from 0% to 100%.
High-/Low-Side Outputs
Four channels can be configured as high-side or low-side digital and PWM outputs to match different load-driving requirements.
Two H-Bridge Pairs
The four configurable high-/low-side channels can be paired to form two H-Bridges for bidirectional load control.
CAN Communication and Programming
The SPC-SFMC-X2424A provides two CAN interfaces and one RS232 interface for communication with other electronic devices in a distributed machine control system.
2× CAN Interfaces
Two CAN 2.0A/B channels support configurable communication speeds from 10 kbit/s to 1 Mbit/s. The default baud rate is 250 kbit/s.
1× RS232 Interface
The point-to-point RS232 interface supports serial communication at up to 115200 bit/s.
CODESYS 3.5 Programming
CODESYS 3.5 supports control-logic development, controller configuration, application debugging, and software updates.
Protection and Diagnostics
The SPC-SFMC-X2424A includes channel protection and controller monitoring functions to help identify electrical faults and abnormal operating conditions.
Input Protection
All input channels include protection against reverse power and ground connection.
Digital Output Protection
Digital output channels include short-circuit feedback, short-circuit protection, and overtemperature protection.
Voltage Output Protection
The reference voltage output and fixed sensor-supply output include short-circuit protection.
Watchdog Monitoring
An internal watchdog function monitors controller operation and helps detect abnormal program execution.
