DESCRIPTION 
  
Interface Module - The Series 2120 PLC Interface Module is an accurate, absolute position sensing device for use with rugged, noise immune 
transducers in harsh environments. It can be used as a simple indicator of position or as a PLC Interface Module generating digital signals, as 
well as serial and analog outputs to feed PLC's. 
  
The Series 2120 PLC Interface Module improves on our popular Series 1994R and 1994L PLC Interface modules. In fact, the Series 2120 combines all 
the features of the Series 1994 into one unit with many added features our customers requested. The Series 2110 and 2120 can be interfaced with 
a Series 951, Series 952, Series 955, and a Series 925.
