Product Features
Allen Bradley 1746-OW16 uses mechanical relay contacts, supports AC/DC mixed load switching, and has high electrical isolation capability (1500V opto-isolation).
Allen Bradley 1746-OW16 has 16 output points, with every 8 points sharing a common terminal (Points per common = 8), making it suitable for controlling multiple distributed loads.
Allen Bradley 1746-OW16 uses color-coded removable terminal blocks for easy wiring and maintenance, requiring the removal of upper and lower fixing screws for disassembly.
Allen Bradley 1746-OW16 is suitable for industrial environments where explosive gases may be present. The epoxy sealing material may be affected by certain chemicals, so regular inspections are required to check for performance degradation, and the module should be replaced if necessary.
Product Working Principle
Allen Bradley 1746-OW16 controls external loads through the mechanical switching of relay contacts. When the module receives a control signal from the processor, the internal relay coil is energized, the contacts close, and the external load circuit is connected; when the signal disappears, the coil is de-energized, the contacts open, and the load is disconnected.
Relay contacts are suitable for switching inductive or resistive loads and do not require additional surge suppression. However, it is recommended to install a suppressor on external inductive loads to extend contact life.
The terminal block supports a maximum wire size of 2mm² (14 AWG), with a maximum of 2 wires per terminal. The tightening torque is 0.9 Nm (8 lb-in.).
