Q1: How many I/O points does the 1761-L32BWB provide?
It provides 32 I/O points total: 20 digital inputs (24V DC, sinking/sourcing) and 12 relay outputs.
Q2: What type of communication does this controller support?
The controller features an RS-232 communication port (8-pin Mini-DIN) supporting the DF1 protocol. It can also connect to a DH-485 network using a 1761-NET-AIC interface module.
Q3: Is this model still in production?
No. The 1761-L32BWB has been discontinued by Rockwell Automation. It is now considered obsolete but remains available through aftermarket suppliers and the used/refurbished market.
Q4: What software is required to program this controller?
It is programmed using RSLogix 500 or RSLogix Micro Starter software. The controller connects to a PC via the RS-232 port using a 1747-CP3 cable.
Q5: What is the recommended replacement for this controller?
Rockwell Automation recommends migrating to the Micro800 series (Micro820 or Micro830) for new installations. The Micro800 family offers enhanced features including Ethernet connectivity, larger memory, and support for the Connected Components Workbench programming environment.
