The Delta DVP24XP200R is an extension unit for the DVP Series PLCs, adding 24 digital input/output points (X/Y extend) to a DVP CPU or backplane. It is a current-production model.
With 24 I/O points per unit, this module gives you a fixed mix of inputs and outputs in a single package. If your machine needs more than 24 points on one extension, the DVP32XP200T offers 32 I/O in the same form factor — but the DVP24XP200R is the right choice when the I/O budget lands at 24 and you want to avoid unused channels.
