Key Features

Features:

6 Versatile Control Modes: Supports "Open/Close/Jog/Self-lock/Interlock/Delay" operations for flexible device management—ideal for motor testing (jog), safety interlocks (interlock), or timed lighting (delay) in industrial or smart home setups.
Dual Protocol Compatibility: Uses industry-standard Modbus RTU (default) or AT commands, working with serial terminals (e.g., Hyper Terminal) or Modbus Poll software. Adapts to both professional PLC systems and DIY projects.
Ultra-Wide Delay Range: Modbus mode offers up to 255s delay (quick timing), while AT mode extends to 9999s (long-term scheduling). Perfect for equipment preheating, security system arming, or periodic device activation.
Low-Power, High-Load Reliability: Runs on 12V DC with minimal standby current (13mA) and 10A multi-voltage capacity (250VAC/12VDC). Safely controls motors, heaters, and locks without overload risks.
Industrial-Grade DIN Rail Mount: Includes a green flame-retardant (VO grade) DIN35/C45 rail box (184x88x42mm). Compact design fits standard control cabinets, simplifying installation in PLC expansions or automation panels.
