DeviceNet Network and I/O Density Scaling
The 1790D-T0B16 integrates CompactBlock LDX I/O functionality with DeviceNet communication for distributed discrete output control. The module receives network commands through DeviceNet and switches 24 VDC sourcing outputs to connected field devices.
The module uses rotary switches for node address configuration and provides LED status indication for module state, network communication, and individual output conditions. The compact design supports distributed I/O placement through DIN-rail or panel mounting configurations.
Within Allen-Bradley industrial control architectures, the module operates as a remote I/O component connected to DeviceNet deterministic networks. Its 16-point output structure allows I/O density scaling by adding distributed output blocks according to field device requirements.
Frequently Asked Questions
Q: What type of output signals are provided by the 1790D-T0B16?
A: The module provides 16 sourcing DC discrete outputs for controlling connected 24 VDC field devices.
Q: How is the DeviceNet node address configured?
A: The node address is selected using integrated rotary switches with an address range from 0 to 63.
Q: Can the module be mounted without a DIN rail?
A: Yes. The module supports both 35 mm DIN-rail mounting and direct panel mounting.
Field Installation Guidelines
- Install the module on a properly secured 35 mm DIN rail or suitable control panel surface.
- Verify DeviceNet network wiring polarity and termination requirements before commissioning.
- Route field output wiring separately from high-voltage power conductors to reduce electrical interference.
- Use the screw clamp terminal block to maintain secure field conductor connections.
- Connect output loads according to the specified sourcing output configuration.
- Confirm node address settings before connecting the module to an active DeviceNet network.
- Check LED status indicators after power application to verify module communication and output conditions.
