Technical Specifications
Number of inputs is 16 non-isolated points arranged in 2 groups of 8. Operating voltage is 240 VAC nominal with a range of 0-264 VAC. On-state voltage is 155-264 VAC. Off-state voltage is 0-40 VAC. Backplane current consumption is 110 mA maximum at 5.0 VDC. Isolation is 1500 VAC for one minute between groups. Response time is one cycle maximum. Dimensions are approximately 110 x 66.8 x 50 mm.
Functional Features
16 individually-labeled LEDs indicate each input point status. One LED indicates backplane operation. Group isolation protects against electrical interference between input groups. Built-in power supply draws all power from backplane, requiring no external user power.
Application Scenarios
AC device monitoring, pushbutton and switch sensing, limit switch interfacing, AC sensor signal acquisition, and general-purpose AC input applications.

Performance Parameters
Maximum response time is one AC cycle. 1500 VAC group isolation provides robust noise immunity.
Material Composition
Industrial housing with optocoupler isolation and high-voltage rated input circuitry.
Structural Characteristics
Compact module with two groups of eight inputs. Snap-in terminal compatibility simplifies field wiring.
Working Principle
The resulting digital signals are transmitted to the CPU as 16-bit discrete input data.
Installation Requirements
Mount on VersaMax I/O carrier. Connect AC field devices to appropriate group terminals. No external power supply is required.
Usage Precautions
Verify AC voltage matches the 0-264 VAC range. Do not apply DC voltage to AC inputs. Maintain group isolation by wiring separate AC phases correctly. Check LED indicators for proper input state verification.
