The EM-MS-02 Multiswitch module is a small programmable multi-use controller board with digital and analog inputs and digital outputs. Typical uses include PWM proportional valve control, PWM valve “soft start”, custom logic for button presses, maintained functions from momentary switches, timed functions from momentary switches etc.

The EM-MS-02 Multiswitch module is a compact programmable controller board featuring both digital and analog inputs along with digital outputs. This versatile module can be configured for various applications such as PWM proportional valve control, PWM valve soft start, and custom logic for button presses. In addition, it supports functionalities including maintaining functions from momentary switches and timed operations from momentary switches. The module is designed to enhance control systems with precise input and output handling. The EM-MS-02-A variant extends the capabilities with analog outputs, specifically tailored to drive Danfoss PVG 32 and PVG 120 valves, making it suitable for systems requiring both digital and analog input and output combinations. Older models like the EM-DC-D and EM-DC-A, which operate bidirectional valves and come with features like short circuit/reverse polarity protection, on-board ramping adjustment, and joystick/separated button inputs, are not recommended for new applications and should be replaced by the newer EM-MS-02 or EM-MS-02-A models.
