Product specifications

9 EXTERNAL INPUT/OUTPUT

The details of input/output depends upon the specifications.

This chapter describes the case that a standard circuit board, AP-RPL-02, is mounted.

9.1 Terminal Block Specifications

For the details of the terminal block specifications, see the rear panel signal table.

All outputs and all inputs are provided at contact points except for analog outputs.

The ON/OFF status is input/output as follows:

Fig. 103 ON/OFF status of a contact terminal

The functions of the terminals are described below:

9.1.1 Range output for analog output

The current momentary value range is output as follows:

9.1.2 Contact input

Note

z The inputs of the AIC start and integration reset do not respond to the changes occurring within

less than 0.1 second.

z The input of telemeter failure does not respond to the changes occurring within less than 0.5

second.

The executed operations depends upon the input status:

AIC start

When the AIC MODE is set to [EXTERNAL], changing this input from OFF to ON causes the

following operation:
