Product Overview
The SPL0601 is an IP67 programmable controller designed for fire trucks, rescue vehicles, and other special-purpose mobile equipment. It provides 66 physical I/O points to connect pressure, level, temperature, position, speed, valve, pump, lighting, and auxiliary control circuits.
Three CAN interfaces, four RS232 ports, one RS485 port, and one Ethernet interface allow the controller to communicate with vehicle ECUs, displays, sensors, communication devices, and other machine subsystems. The controller supports CODESYS 3.5 programming and operates from an 8–32 VDC power supply.

PWM and Current Control
The SPL0601 provides configurable PWM, high-side, low-side, and H-Bridge outputs for controlling proportional valves, solenoids, motors, and other electrical loads.
6 Current-Feedback PWM Outputs
Six high-side PWM outputs provide current feedback from 0–3 A for monitoring and controlling connected loads.
Closed-Loop Current Control
Closed-loop current regulation from 100–1500 mA supports stable control when the load or supply voltage changes.
Configurable PWM Frequency
PWM frequency can be configured from 10–2000 Hz with an adjustable duty cycle from 0% to 100%.
High-/Low-Side and H-Bridge Control
Four outputs can operate as high- or low-side PWM channels, or be paired to form two independent H-Bridges.
Communication Interfaces
The SPL0601 combines CAN, Ethernet, RS232, and RS485 interfaces for communication between the controller and other electronic devices within a mobile machine control system.
3× CAN Interfaces
Three CAN 2.0A/B channels support communication speeds from 20 kbit/s to 1 Mbit/s, with a default baud rate of 250 kbit/s.
1× Ethernet Interface
The Ethernet interface supports TCP/IP and user-defined application-layer protocols. It can also be used for programming, debugging, and controller updates.
4× RS232 Ports
Four RS232 ports provide point-to-point serial communication with a maximum baud rate of 115200 bit/s.
1× RS485 Port
One RS485 port supports user-defined serial communication with a maximum baud rate of 115200 bit/s.
Protection and Diagnostics
The SPL0601 includes power monitoring, output protection, and internal diagnostic functions to help detect electrical and controller operating faults.
Voltage Monitoring
The controller monitors overvoltage and undervoltage conditions and provides an undervoltage cut-off function.
Output Protection
Digital output channels include short-circuit feedback, short-circuit protection, and overtemperature protection.
Input Protection
Input channels include protection against reverse power and ground connection.
Controller Diagnostics
A watchdog function, program diagnostics, and system self-diagnostics monitor controller operation.
| Operating voltage | 8–32 VDC |
|---|---|
| Short-duration overvoltage | 36 V for up to 10 seconds |
| Undervoltage detection | At or below 9 V |
| Undervoltage cut-off | At or below 7 V |
