idt IO-M HSPWS
Smart Power Switching Module
Safely and precisely drive high-current hydraulic, pneumatic, and proportional valves up to industrial safety standards (STO) without stressing your PLC's standard digital outputs.
The New Muscle Power of Your Automation System
Standard PLC outputs typically supply up to 0.5A, requiring external relay modules to drive high-power solenoids. The idt IO-M HSPWS is engineered to eliminate this complexity. Featuring an 8-channel architecture, it directly drives your hydraulic and pneumatic valves by delivering up to 3A per channel. Furthermore, with PWM support ranging from 100 to 200 Hz, you can control proportional valves seamlessly.
Why Choose idt IO-M?
This hardware is not just an output board—it is an active barrier protecting your system:
Your PLC is Safe: Optocoupler ICs provide complete electrical isolation between your PLC outputs and field-side high-current circuits (24VDC).
Hardware Safety (STO): When an emergency stop is triggered, power is hardware-cut via the STO1_IN and STO2_IN inputs without relying on software execution.
Smart Protection: On-board smart power MOSFETs feature built-in short-circuit protection. Additionally, an on-board 45°C thermostat automatically engages the cooling fan during high-temperature conditions to assist your cabinet's thermal management.
