Concept
Each device can detect its order in the chain of connected devices and assigns itself an address accordingly. This auto-addressing feature is provided by the terminal base backplane.
Concept
The devices are designed mainly for installing on DIN rails in a cabinet.
Concept
The DO-FA-12 and DO-FA-12-H Central IO modules are 12-channel, Form A relay, digital output I/O modules.
How to
You install a terminal base on a horizontal DIN-rail prior to connecting it to its neighboring terminal bases.
Concept
The I/O bus imposes restrictions on the number of devices that can be connected to the bus and what type of devices that are allowed on certain positions.
Concept
The I/O bus consists of the following parts:
Concept
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.
Concept
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).
Concept
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.
Concept
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:
