The M1322 (24Vdc version) 16DI modules accepts 16 digital inputs powered externally from either a positive or negative common circuit. The inputs are arranged into two independent groups of eight inputs, each group with its own common terminal. The groups are isolated from each other to allow them to be used in separate electrical circuits.

All inputs are opto-isolated from the system logic.

The module may be inserted into any I/O slot in a Maxiflex system.

The status of each input is displayed on a 4×4 LED matrix on the front of the module.

The module can be inserted or removed while the system is powered.
