Product Features
Allen Bradley 1746-IV32 employs 1500V AC isolation technology between the backplane and I/O, compliant with the IEC 61131-2 standard, effectively resisting strong electromagnetic interference generated by devices such as variable frequency drives and servo motors.
Each channel is equipped with a 2.5A non-replaceable fuse, supporting reverse polarity protection to prevent abnormal voltages from damaging the module. Each channel can be configured with a 1ms or 10ms filter time, effectively suppressing on-site noise and ensuring signal stability.
Allen Bradley 1746-IV32 features four independent common-mode terminals, allowing connection to sensors of different voltage levels and reducing external power supply complexity. It supports 15-30V DC input (at 50°C), compatible with various industrial sensor signals.
Allen Bradley 1746-IV32 operates at temperatures ranging from 0°C to 60°C and can be stored at temperatures from -40°C to +85°C, meeting the demands of long-term operation in harsh environments.
Allen Bradley 1746-IV32 allows module replacement without powering down, minimizing downtime. Built-in LED indicators display real-time channel status, facilitating quick fault diagnosis.
Product Working Principle
The DC signal from the field device is connected to the module via a terminal block, with each group of channels having an independent power supply for the common terminal.
Allen Bradley 1746-IV32 can convert the analog signals to digital signals (0 and 1 values) and send that digital signal to the SLC 500 PLC Processor over the backplane bus.
Allen Bradley 1746-IV32 Builtin digital filters remove high frequency noise, 1500V AC Isolation on I/O provides reliable signals and protection from high voltage spikes.
Allen Bradley 1746-IV32 can monitor channel status in real time, trigger overvoltage protection when abnormalities occur, and alert via LED indicator lights.
