The DIM84NDIN is a low voltage eight channel 12V or 24V PWM lamp and LED dimmer module controlled by a universal 0-10 volt control signal. 0V on the input means the lamp/LED is fully off, 10V is fully on, and everywhere in between. The module is suitable for interfacing to any device that outputs a 0-10V or 1-10V control signal including most PLCs, lighting controllers, Crestron™ or Lutron™ devices, and many others.
The module is suitable for controlling common anode LEDs and incandescent lamps and is particularly suitable for high-power RGBW applications.
The module features eight independent low-side PWM output channels controlled by eight independent 0-10V control signals all sharing a common supply. The control inputs are designed to accept analogue 0-10V control signals from a PLC, lighting controller, Crestron™ controller, or similar. As the input signal is varied between 0 and 10V the connected lamp changes in brightness synchronously. An input of less than 0.2V turns the lamp fully off, and more than 9.8V turns the lamp fully on.
A 'Full-On' input is provided on the module for emergency lighting applications. When this input goes positive above 4V, all eight channels are immediately brought up to full brightness, regardless of the control input voltage. The channels revert to normal brightness when the Full-On input goes below 4V. Please note this is not a substitute for an approved, redundant, emergency lighting system.
The control inputs are protected against over-voltage, although they should never exceed the module's supply voltage. The control voltage input and the DIM84NDIN supply voltage are not electrically isolated from each other and share a common supply.
Please note, as part of the internal fault protection circuitry, a small current is permanently applied to the output terminals. When the dimmer is fully off, this current may cause some sensitive LEDs to glow. The effect can be mitigated by applying a resistor in parallel with the LEDs, value dependent on supply voltage and LED sensitivity.
The module is finished in a 4 unit wide standard vented DIN-rail mount enclosure.
Important: On the original (non V2) version of the module both +Supply terminals were tied together. The datasheet for the original (non V2) version is here for legacy purposes.
