Saia PCD1.T2000-F00 (RF modem, RS-485)*
The PCD1.T2000-F00 RF modem transparently transfers the connected RS-485 interface via radio. The frequency
range of 869 MHz can be used in Europe. The devices can therefore be operated using the self-declaration with no
additional approval required. The modules have an integrated antenna that enables data to be transferred with no
additional hardware required. If an external antenna is required, it can be connected via a connector on the front
plate. The classic hat-shape enables the 35 mm wide housing to fit into an electrical control cabinet. The device has
rotary switches for parameter configuration that allows the radio power and radio channel to be selected.
