MU-262, MU-462
These modules are designed especially for propotional control of technological systems and are equipped with two (MU-262) or four (MU-462) pulse-width modulators (abbreviation PWM). Additionally, the MU-262 module offers two digital inputs for monitoring the state of digital signals (switches, etc.) with counter capability.
PWM allows first to configure a wide range of period time and then continuously control the pulse width with 1ms increments. This control method is similar to proportional control by an analogue signal and is used for systems with very long response time (heating etc.).
Both or all outputs can be individually interconnected to PWM, or can work as standard digital outputs.
The digital inputs and outputs are isolated not only from other circuits (power supply and RS-485 interface), but from each other, and work with industrial signal levels.
