GENERAL SPECIFICATIONS

Construction: Plug-in

Connection: M3.5 screw terminals

Housing material: Flame-resistant resin (black)

Isolation: Input to output 1 to output 2 to power

Zero adjustment: -5 to +5 % (front)

Span adjustment: 95 to 105 % (front)

Setpoint adjustments: 270°-turn screwdriver adjustments

(front); 0 – 100 % independently

Remark: The ASP has low-end cutout function below 2 – 5 %

input. A setpoint below this equals 0 %.

Front LEDs: LED turns on at a tripped condition; red for

output 1, green for output 2

Power ON timer: Relays de-energized for approx. 2 seconds

after power is turned on.

Low-end cutout: 2 to 5 %
