6.17 MR-J3-D05 safety logic unit
Functions and configuration
Outline
The MR-J3-D05 has two systems of output for the SS1 function (delay time) and the STO function each.
Specifications
*1 An inrush current of approximately 1.5 A flows momentarily at power-on. Take the inrush current into account when selecting a power
supply.
*2 The service life lasts until the power is turned on 100,000 times.
*3 A number and axis name are put in the _ portion of a signal name.
*4 For details of test pulse input, contact your local sales office.
