The RP-C 230 V controller models have a 24 VAC (19 VA) Class 2 output that can be used to power external loads such as actuators, relays, or indicators. The external loads can be controlled using the controller's solid-state relay (SSR) or relay outputs.
The RS-485 adapters are RJ45 to screw terminal block adapters and are offered as accessories for some BACnet/IP controller models when the controllers are used in certain network configurations.
The universal inputs/outputs are ideal for any mix of temperature, pressure, flow, status points, and similar point types in a building control system.
You connect an Isolated RS-485 Adapter (via a separate connection cable) to a BACnet/IP controller to convert the controller's RS-485 RJ45 interface to screw terminals, which is required to connect the controller to a BACnet MS/TP (RS-485) network. You use an Isolated RS-485 Adapter (SXWISORS48510001) when the BACnet MS/TP network is comprised of isolated controllers, such as MNB BACnet devices (zone controllers) and selected others.
