The ne24.24M series is built around a standard 4x4 base unit which is expanded with field-installable 4-channel input and output modules. The 12x8 Logic configuration is created by adding two 4-channel input cards and one 4-channel output card to the base unit's expansion slots. The integrated logic card, which occupies an expansion slot, provides General Purpose Outputs (GPOs) to control external devices like relays, projection screens, or lighting based on predefined logic. All configuration and control are done via a PC using Ashly's Protea NE Software over an Ethernet or RS-232 connection. The unit's tamper-proof design, lacking front-panel controls, and multi-level software security ensure that settings remain secure after installation.
