FAQ
FAQ
Q1: What is the Allen-Bradley 1790-16BV0X used for?
A: It is a 16-point digital input expansion module designed to increase the input capacity of a compatible CompactBlock LDX DeviceNet I/O system.
Q2: What does universal input mean?
A: It supports both sinking and sourcing DC input wiring configurations, providing flexibility when connecting different types of field sensors.
Q3: What is the nominal input voltage?
A: The nominal input voltage is 24 V DC, with an ON-state voltage range of 9.6–28.8 V DC.
Q4: How many input channels does it have?
A: It provides 16 independent digital input channels.
Q5: What type of connector does it use?
A: It uses a 37-pin D-shell connector for field wiring.
Q6: Is the 1790-16BV0X compatible with all DeviceNet systems?
A: No. It is an expansion module designed for compatible CompactBlock LDX base blocks. It cannot operate independently and must be connected to a compatible base module.
Q7: Is the 1790-16BV0X discontinued?
A: Yes. Rockwell Automation lists September 30, 2023, as its discontinuation date. The product is classified as an engineering replacement, rather than having a specified direct replacement model.
Q8: What are the dimensions and weight for shipping?
A: The distributor lists approximately 0.31 kg net weight. The approximate dimensions are 104 × 42 × 52 mm and should be verified against the actual unit. Add protective packaging when calculating export shipment weight and volume.
