Elma Relay Attenuator switch, 2 Channels SMT populated, thin-film, 10K 64 positions

The Relay Attenuator (new Version) is an extremely versatile ladder type, 6-stage stereo attenuator with constant input impedance featuring 64 positions without infinite position. The tiny module can be locally operated by encoder or motorized potentiometer, while providing an IR remote option with teach-in feature. It can also be directly UART bus controlled by a host system for distributed multi-module operation, featuring 16 selectable node addresses so up to 16 modules can be operated in a multi-module configuration. The attenuator comes with either pre-populated SMT resistors or it can be populated by the customer using THT resistors. The on-board DIP switch is either used to set the baud rate and the node address (host control), or to configure various functions in the local mode or to select the node address in the host mode. For position indication, especially when operated by an encoder, a display module is also available.
