MODEL: M2AS
GENERAL SPECIFICATIONS
Construction: Plug-in
Connection: M3 screw terminals (torque 0.8 N·m)
Housing material: Flame-resistant resin (black)
Isolation: Input to output to power
Overrange input: -14 to +113.5 %
When the relay’s untripped point relative to the preset
alarm setpoint and deadband is out of this range, the relay
remains latched.
Setpoint adjustments: Thumbwheel switches (front);
0 – 99 % independently; 1 % increments
Deadband (hysteresis) : Thumbwheel switches (front);
1 – 99 % independently; 1 % increments
(latching output when set to 00)
Front LEDs: Red light turns on when the coil is energized.
Reset input: Latched output reset with the front control
button or remotely via base socket terminals.
