The AJ65SBTB1-32D1 module is designed to be used with the MELSEC-Q Series PLCs and it provides 32 digital input channels. Each channel can detect the on/off status of an external signal, such as switches, sensors, or other devices. The module utilizes a common positive side configuration, which means that the common terminal of the input channels is connected to the positive voltage supply.

This module supports both sink and source types of inputs. Each input channel has an LED indicator to indicate the status of the corresponding input. It also features built-in surge absorbers to protect against electrical noise and voltage spikes.

The AJ65SBTB1-32D1 module is typically used in automation and control applications where a large number of digital inputs need to be monitored by the PLC. It is commonly found in various industries, including manufacturing, process control, and building automation.
