Communication Function
The 1769-SM1 provides an interface between DPI or SCANport devices and compatible Compact I/O-based control architectures. Its three communication channels support connections through the adapter, allowing the control system to exchange data with compatible connected devices. Confirm the required device interface and system configuration before selecting the module.
Mounting and Configuration
The module supports panel mounting or DIN rail mounting. Its IP00 rating and open-type enclosure classification indicate that it does not provide a sealed enclosure for protection against dust or water ingress. The installation must therefore account for the control cabinet’s environmental protection requirements.
The specified power supply distance rating is 8 modules. This value is relevant when checking module placement within the system configuration; it should not be interpreted as support for eight communication channels.
Frequently Asked Questions
Q: What is the primary function of the Allen-Bradley 1769-SM1?
A: It provides a communication interface between DPI or SCANport devices and compatible Compact I/O-based control systems, including MicroLogix 1500, CompactLogix, and remote 1769-based nodes.
Q: How many communication channels does the 1769-SM1 provide?
A: The supplied specifications identify three communication channels. Confirm the required connections and device interfaces against the intended system configuration.
Q: What does the power supply distance rating of 8 modules mean?
A: It specifies the stated power supply distance limit in terms of module positions within the system configuration. It is not the communication channel count or a statement that eight additional modules can always be installed; verify the applicable controller and power supply configuration.
