Description
The 1790D-T0B16 is a 24 VDC discrete output base block manufactured by Allen-Bradley for the CompactBlock LDX I/O series. Operating as an active node on a DeviceNet network, it provides 16 sourcing output points in a compact, open-style IP20 enclosure. The module integrates output logic control, field power distribution, and a built-in DeviceNet communication adapter into a single hardware footprint.
Sourcing Output Circuitry and Screw Termination
The 16 digital output channels deliver 24 VDC sourcing signals, routing power from the external field supply directly to connected loads such as solenoid valves, relays, and indicator lights. Field wiring connects directly to fixed screw-clamp terminal blocks, offering secure, vibration-resistant connections for industrial installations. The front panel includes status LEDs for real-time monitoring of network health and individual channel logic states.
DeviceNet Commissioning and Local System Expansion
Network node addressing from 00 to 63 is set via two front-panel rotary switches, which are sampled by the internal controller upon power-up. The module supports automatic baud rate detection for simplified network commissioning. As a base module, the 1790D-T0B16 can operate standalone or accept up to three CompactBlock LDX digital expansion blocks (such as the 1790-0B16X or 1790-16BV0X) connected via ribbon cables to increase node I/O density.
