AutomationDirect D2-240 Industrial PLC Processor Module

The AutomationDirect D2-240 CPU is a DirectLogic DL205 processor module with 2.5K words of ladder-logic memory, delivering compact, cost‑effective control for small to mid‑size automation tasks. As a member of the DL205 family, it provides two RS‑232 serial interfaces for programming and device communications: Port 1 uses a 6P6C phone‑jack RS‑232 interface at 9,600 baud with fixed addressing and odd parity, while Port 2 (available only on the D2‑240) is an RJ12 serial port for additional connections. The D2‑240 can be paired with AutomationDirect’s D2‑DCM Data Communications Module to operate as a DirectNet master/slave or DirectNet peer, and it can also function as a MODBUS RTU slave within a DirectNet/MODBUS network. Programming and integration are typically done with DirectSOFT and DSData, alongside DirectNET‑compatible HMIs, making it a practical choice for legacy DL205 systems or projects leveraging DirectNet communications. Although listed as a retired product by AutomationDirect, the D2‑240 remains in use in many DL205 installations, valued for its DirectNet compatibility, K‑sequence support, and straightforward ladder‑logic deployment.
