ArmorBlock Digital I/O Blocks

Sealed housing rated for IP-69K and NEMA 4X eliminate enclosure costs.
Low installation cost and easy to replace without rewiring because industry-standard M12 DC micro connectors are used for connection to the DeviceNet network and auxiliary power supply. I/O connectors are sealed M8 pico or M12 DC micro styles.
8-point and 16-point self-configuring I/O provides flexibility for any input/output combination.
Removal and Insertion Under Power makes it possible to replace a module without impacting the network operation.
Isolated auxiliary power maintains power to the outputs if main power fails so that you can have the option of holding outputs in their last state.
Outputs electronically protected from failing with option to autorestart or latch off.
Complies with Open DeviceNet Vendor Association, Inc. (ODVA) conformance test software.
