; an oversampling and averaging nique further enhances this resolution. Inputs are procd against transient and sadysta overvoltage conditions. Alog inputs use AI references in the controlr. A of K words of AI memory is currently ailab in the controlr. Ea input uses one word bits of AI memory. Field wiring is de a board and the is meanically keyed ensure correct replacement with a similar type in the field. references are user configurab without the use of jumpers or DIP swis on the . Configuration is done using the configuration function of the MSDOS or Windowsprogramming software running on Windows or Windows NT over Ethernet TCPIP or through the SNP port. The Programming Software configuration function is instald on the programming device. The programming device can be an IBM XT AT PS or patib Persol pur.
