NZ2EX2B1-16D is a 16-point DC input module for Mitsubishi's compact MELSEC platform (iQ-F or similar). Rated 24 VDC with a 6.0 mA typical sink per point, it accepts the 20.4 to 28.8 VDC range with ≤5% ripple. The module itself draws 20 mA or less from the backplane when all points are ON. Key layout constraint: this module does not support connection of multiple extension modules — it's a single-slot add-on, not a daisy-chainable unit. Confirm the CPU's expansion policy before committing the BOM.

Frequently asked questions
Can NZ2EX2B1-16D replace a Q312DB in an existing panel?
No. The Q312DB is a MELSEC-Q unit with different dimensions, weight (0.54 kg vs 0.19 kg), backplane interface, and DIN-rail adapter requirement. These are from separate product families and are not mechanically or electrically interchangeable.
What is the input rating per point?
24 VDC, 6.0 mA typical per point, with an allowable voltage range of 20.4 to 28.8 VDC and ripple rate of 5% or less.
