The Extron ECM DIO8 is a compact digital I/O control module for Extron eBUS-enabled control systems. This easy-to-use control module connects to an IPCP Pro control processor to interface with a variety of I/O devices, including sensors and contact closure buttons. The ECM DIO8 offers eight software selectable digital I/O ports and a 24 VDC output to provide power to a sensor. For convenient integration, eBUS control modules are linked to the control processor or to other eBUS devices using a single cable that carries both power and communication. The ECM DIO8 mounts in a US single gang, Flex55, EU, or MK enclosure or can be mounted to any flat surface with the included dual-lock fastener.
