Suitable replacement

100x_100

We recommend the Watson Smith type 100X I/P converter as the most suitable replacement for the Type 423. The only noticeable different is the shape of the unit. The type 423 is slightly bigger with a body similar to the type 422.

However the specifications are almost the same as the type 100x with failsafe & IP65 rating so the type 100x is suitable in most cases.
