Insulation block
In the chart below, circuit divided by the lines are insulated from other circuits.
Measuring input terminals
Remote input terminals R/L (analog) DI terminals
Control output 1/2 terminals
(current output type/SSR drive pulse output type/
voltage output type)
Control output 1/2 terminals (ON-OFF pulse output
type)
Event output 1/2 (mechanical relay output)
terminals
Communications terminals R/L (digital) DI
terminal
External signal input (DI1 to 5) terminals
Event output 5 to 9 (open corrector output)
terminals
*For “24V AC/DC”, power terminals are at secondary side.
*Between control output 1/2 (ON-OFF pulse output type) and event
output 1/2 (mechanical relay output) is isolated.
