It features two output groups, each with eight channels and a dedicated common terminal, allowing one group to operate with AC voltage and the other with DC, or both with the same type of voltage. The module eliminates the need for interposing relays when controlling mixed-voltage loads, reducing panel space and wiring complexity. With a step response of 60 ms input and 2.5 ms output, it provides efficient performance across various automation tasks. To ensure longevity and protect against voltage transients, the use of external surge suppression devices is recommended. Key Features: Output Channels: Sixteen normally open relay outputs for flexible switching. Voltage Range: Supports 5–265 VAC and 5–125 VDC operation, accommodating diverse control requirements. Grouping: Configured into two groups of eight points each, with independent common terminals for AC or DC assignment. Current Ratings: Provides 1.5 A per output at 120 VAC and 1.2 A at 24 VDC, with higher make/break ratings for various voltages. Relay Type: Dry contact outputs eliminate the need for interposing relays when switching mixed voltages. Step Response: Fast response time of 60 ms in and 2.5 ms out for efficient process control. Protective Measures: External surge suppression recommended per channel to prevent relay wear and extend service life. Integration: Designed for seamless installation in SLC 500 chassis, supporting scalable and reliable automation systems. The 1746-OW16 delivers the reliability and precision required for discrete control in industrial automation environments.
