Switch/Keypad Input and 1 Zone PDM Controller, dimming, communicating
Description:
The Dimming Module controls a Zone of lights by reading input signals from attached switches or keypads connected to the PDM Port, and creates a Channel signal on the PDM. Up to 128 driver modules can listen to the Channel creating a group, or Zone, of lights. The L2-DM can be “stacked” underneath any driver so both switch inputs and lights can be attached to the same PDM Port. Only one L2-DM is allowed per Channel to create the PWM Channel signal. The L2-DM also sends 12VDC Accessory Power from the Accessory Power Regulator (L2-APR) to the RJ45 Port through a protection fuse. An L2-APR is required to power the microcontroller in the L2-DM. Up to 16 L2-DM are powered by the L2-APR in the middle of the PDM. L2-DM can receive commands and transmit their output status over the PDM communication bus to interface to third party control systems and the L2-EGW Ethernet Gateway. Solving many more roles than just a dimmer for lighting, eleven modes of operation allow the L2-DM to read on/off, momentary, top/bottom switches, motion sensing, occupancy sensing, exhaust fan controls, ceiling fan controls, doorbells, and 1 to 8 button keypads. No software or gateway is required for most configuration steps, even setting basic lighting scenes thanks to 1 button macros. Advanced settings can be accessed using the L2-EGW.
