Description

The Samkoon S-E8X8T-C is a programmable logic controller (PLC) or I/O module designed
for industrial automation, featuring a combination of universal inputs and transistor
outputs. Below is a structured breakdown of its likely specifications and applications based on
the model number and Samkoon’s product conventions:
Key Specifications:
• Universal Inputs (8X):
➢ 8 configurable digital/analog input channels that can be programmed
to accept:
▪ Digital signals (e.g., 24V DC for switches, sensors).
▪ Analog signals (e.g., 0–10V, 4–20mA for sensors like pressure
transducers or temperature devices).
➢ Flexibility to switch between modes via software.
• Transistor Outputs (8T):
➢ 8 high-speed digital outputs (typically 24V DC, NPN/PNP transistor
type).
➢ Suitable for switching inductive loads (e.g., relays, solenoids, small motors).
➢ Output current ratings (e.g., 0.5A per channel) depend on the model;
check datasheet for limits.
• Communication (-C suffix):
➢ Likely includes built-in communication ports (e.g., RS-485/Modbus RTU,
Ethernet, or CANopen) for integration with HMIs, SCADA systems, or other
PLCs.
➢ May support protocols like Modbus TCP/IP or proprietary Samkoon
protocols.
• Power Supply:
➢ Typically 24V DC industrial power input.
• Additional Features:
➢ High-speed counting (for encoder/pulse signals).
➢ PID control for automation loops.
➢ Expandability via Samkoon’s I/O modules or bus systems.
Applications:
• Machine Control: Discrete automation (e.g., packaging machines, assembly
lines).
• Process Automation: Hybrid systems requiring both analog sensing (e.g.,
pressure, temperature) and digital actuation.
• Material Handling: Conveyor belt control, sorting systems.
• Energy Management: Monitoring and controlling power consumption via
analog/digital signals.
Installation & Wiring:
• Input Flexibility: Configure inputs as analog or digital via software (e.g., set
voltage/current ranges for analog mode).
• Output Protection: Use flyback diodes for inductive loads (e.g., relays) to protect
transistor outputs.
• Noise Reduction: Separate analog signal cables from power lines to avoid
interference.
Configuration & Software:
• Programming: Use Samkoon’s SAMS3 HMI software or PLC programming
tools (e.g., ladder logic, function blocks) to configure I/O modes, logic, and
communication.
• Communication Setup: Assign Modbus addresses, baud rates, and network
parameters for integration.
Troubleshooting Tips:
• Input Errors: Verify configuration (e.g., analog vs. digital mode, voltage/current
range).
• Output Failures: Check for overloaded channels or damaged transistors.
• Communication Issues: Confirm protocol settings (e.g., parity, stop bits) and
cable integrity.
Recommendations:
• Documentation: Always refer to the official Samkoon S-E8X8T-C datasheet for
exact I/O ratings, communication protocols, and wiring diagrams.
• Compatibility: Pair with Samkoon HMIs (e.g., AK or ST series) for seamless
visualization and control.
• Upgrades: If discontinued, contact Samkoon support for migration options to
newer models (e.g., S-Series PLCs).
