IntelliFlex I/O Contact Closure Interface provides integration for third-party controllers that require contact closures. Configuration is performed by utilizing the onboard programming buttons; no rewiring or external devices are needed. It allows up to six contact closure inputs grouped into three sets of up/down signals to be connected. Each group can control any number of roller shades on an IntelliFlex I/O network. Flexible control signal options include full movements to motor limits and manual control to intermediate stops. Power and communication provided through the use of a single Ethernet cable.
