Event input (2 points) 
(*1) Thermocouple, RTD, Direct current and DC voltage can be selected by keypad. 
(*2) Only one option can be selected from Option 1 and Option 2 respectively. 
(*3) Event output EV1 is standard. 
The following outputs can be selected in [Event output EV1/EV2 allocation] by keypad: 
Alarm output (12 alarm types and No alarm action), Heater burnout alarm output, Loop break alarm output, 
Time signal output, Output during AT, Pattern end output, Output by communication command, Heating/Cooling 
control output OUT2 (for EV2 option only). 
For Event output EV1/EV2, Heater burnout alarm output and Output by communication command are available   
when C5W, EIW, C5 or W option is ordered. 
(*4) For the BCS2, Event input (2 points) is not available. 
(*5) For Direct current output type, Heater burnout alarm does not work. 
(*6) For the BCS2, 1 point of Event input is available.
