M450A-ES
Addressable input / output interface. Loop powered and short-circuit isolator included. Provides a voltage free relay output (2 A a 30 V) to operate other devices like door holders, signaling equipment, elevators, and one single switch input to monitor different signals to be supervised individually by the panel, like door opening, flush detectors, other devices etc,. Led status indicator. Size: 154 x 109 x 50 mm.

M450A-C

Addressable conventional zone interface. Loop powered and short-circuit isolator included. Allows power and operation of a zone of conventional detectors giving a collective address in the main panel. Led status indicator. Size: 154 x 109 x 50 mm.

M450A-4.20

Format 4-20 mA input interface. Loop powered and short-circuit isolator included. Provides connection with the main system of any standard 4-20 mA format external device to be individually controlled (gas monitoring, level, pressure sensors, etc.). Led status indicator. Size: 154 x 109 x 50 mm.

M450A-A

Short-circuit isolator. Allows sensing and isolating faults on the loop avoiding the loss of devices in a short circuit event. Led status indicator. Size: 154 x 109 x 50 mm.
