This section provides recommendations on minimum wire sizes (cross-sectional areas) and maximum wire lengths for the wires connected to the screw terminals of Central IO modules, AS-B servers, RP and MP controllers, and IP-IO and RP-IO I/O modules. Recommendations on minimum wire size and maximum cable length for the digital inputs of the RP controller expansion modules, the DALI bus of the DALI light modules, the SMI Interface of the SMI blind modules, the Zigbee DALI and 0-10V modules, and the KNX Modbus gateway are also provided. The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.
Output modules support a number of electrical types, such as digital, tristate, and digital/tristate pulsed outputs, or analog outputs. The available output modules include the following:
You install a terminal base on a horizontal DIN-rail prior to connecting it to its neighboring terminal bases.
The DO-FC-8 and DO-FC-8-H Central IO modules are digital output, Form C relay, 8-channel I/O modules.
The devices are designed mainly for installing on DIN rails in a cabinet.
It is important to perform the grounding correctly for the following reasons:
The terminal bases are used for SpaceLogic devices that are based on the patented two-piece design. The terminal base provides the I/O bus to the electronics module installed on the terminal base as well as to the SpaceLogic device installed to the right (next terminal base in the chain).
The Status LED on the front of the automation devices changes color and flashes to indicate the status of the device.
Use the power budget to calculate the maximum number of devices that the power supply can supply. If more devices are used, additional power supplies must be added to the I/O bus.
The I/O bus is a common bus that delivers power, address information, and communication to all devices connected to the bus. The I/O bus is provided to the devices through the backplane in the terminal bases. The term I/O bus also denotes the chain of devices that are connected together.
