MODEL: M2AS1

M2AS1 SPECIFICATIONS

ES-5064 Rev.12 Page 2/5

http://www.m-system.co.jp/

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 LED: 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.
