TL-DI1

The TL-DI1 device has 3 fully independent 9-24VDC input channels.
Each input channel is electrically isolated from the other channels and from the control electronics, and has its own protection fuse located on the back of the device.
The input channels receive information from other devices external to the system (photocells, buttons, switches, timers, presence or movement detectors, or contacts generally coming from sensors or other electronic devices external to the PLS system).
The TL-DI1 devices are auxiliary to the TL-DO1 devices, allowing to expand the capabilities and functions of the entire PLS system, through appropriate configuration.

The PLS devices represented in the images may be partially different (in shape, colors, labels, characteristics shown, version number, etc.) from the PLS devices currently available for sale.
