19-30 VDC Diagnostic Output 16 Pts (36 Pin)
A-B 1756-OB16D
As a 16 channel DC output module of the Rockwell ControlLogix series, 1756-OB16D adopts an optocoupler isolation+MOSFET array architecture, with a maximum single point load of 2A and independent protection between channels. The measured response delay is stable at 1.8ms ± 0.2ms. Its design abandons the mechanical wear problem of traditional relay schemes and is suitable for high-frequency switching scenarios. It is a key interface between the automation control layer and the actuator. From circuit layout to EMC protection, this module embodies the engineering precision of industrial grade modular design.
