Installation & Maintenance Guide
Mount the module on a standard DIN rail. Ensure adequate clearance for ventilation. Connect the DeviceNet cable to the open-style connector.
Wire field devices to the removable terminal blocks. Use copper wire rated for 75 degrees Celsius. Torque terminals to 0.5 Nm.
Set the node address and baud rate via the rotary switches on the front panel. Power up the module and verify communication with the master scanner.
Periodically inspect for loose connections and contamination. Keep the module clean and dry. Replace only with an identical module from Allen-Bradley.
Frequently Asked Questions (FAQ)
What is the primary function of 1790D-T16BV0?
This module provides 16 digital I/O points for remote control in a DeviceNet network. It connects sensors and actuators to a PLC or controller.
What type of cable is required for DeviceNet communication?
Use a standard DeviceNet trunk cable with a drain wire. The cable must be terminated with 120 ohm resistors at each end.
Can the 1790D-T16BV0 be used with other brands of PLC?
Yes, as long as the master scanner supports DeviceNet protocol. The module operates as a generic DeviceNet slave.
What is the maximum cable length for DeviceNet?
The maximum trunk length depends on the baud rate. At 125 kbps, the maximum length is 500 meters. At 500 kbps, it is 100 meters.
Does the module require an external power supply?
No, the module includes an integrated 24V DC power supply. It draws power directly from the DeviceNet network.
