The Allen-Bradley 1756-OG16 is a ControlLogix digital output module that provides 16 0–5 V DC TTL outputs with low-true signaling. The module uses a 20-pin terminal block to service all 16 outputs and is designed for mounting in a ControlLogix I/O chassis backplane. Each channel is a DC TTL output suitable for energizing external devices such as relays or LED indicators in industrial automation circuits. As part of the 1756 digital I/O family, the 1756-OG16 integrates with ControlLogix controllers and other I/O modules to enable synchronized control across a rack.
