Function

Controlling DC loads: This module can directly drive DC loads ranging from 10 to 60 VDC (such as indicator lights, relay coils, solenoid valves, etc.), with a nominal voltage of 48 VDC, making it suitable for industrial control scenarios that require higher voltages.

High-performance output: It provides 16 non-isolated output channels, each channel supporting A maximum resistive load of 2 A, and the total module current does not exceed 8 A, suitable for the control requirements of various industrial equipment.

Fast response: The output signal delay is extremely short (0.2 milliseconds from on to off, 0.1 milliseconds from off to on), suitable for control applications that require rapid switching.

Modular design: It can be installed in the 1771 series I/O racks (except for the 1771-A4 rack), and a current of 400 mA can be obtained from the rack power supply through the backplane, facilitating integration into the existing PLC-5 system.

Compatibility: It can directly drive various Allen-Bradley input modules (such as 1771-IQ, 1771-IBD, 1771-ICD, etc.), facilitating system expansion and signal transmission.

Protective design: Supports hazardous location certification (such as C-TICK, CE, CSA, UL), and has a low leakage current (0.5mA) to ensure safety and reliability.

Application scenarios

Manufacturing plant: It is used to control DC equipment on the production line, such as solenoid valves, relays, indicator lights and actuators, and is suitable for industries such as automotive manufacturing, food processing and electronic product production.

Process control system: In the chemical, oil and gas or pharmaceutical industries, it is used to precisely control equipment that requires a power supply of 10-60 VDC, such as pumps, valves or sensor trigger devices.

Mechanical automation: Drives DC motors, electromagnetic clutches or brakes in mechanical equipment to ensure rapid response and reliable operation, suitable for packaging machinery, material handling systems, etc.

Energy management system: In power protection or distribution systems, it is used to control the switchgear or signal lights of DC power supply to meet the requirements of high reliability.

Special voltage applications: Due to its support for a nominal output of 48 VDC, it is suitable for control scenarios in telecommunications equipment or certain special industrial devices that require non-standard voltages.
