Datasheet

12-fold Switch Actuator with Current Measurement (AMS-1216.03)

The MDT 12-fold switch actuator with integrated current measurement provides reliable control up to 16 A per channel. With support for C-Load (140 µF) and an integrated energy meter function (Wh/kWh), this device is ideal for energy management and automation in smart buildings.

Product Features

• Fast reaction (< 1 second) in master/slave configuration
• Integrated energy meter function for precise consumption measurement (Wh/kWh)
• Individual programming per channel via ETS software
• Extended status functions (inverted, cyclic, when locked)
• Priority and forced operation with automatic release time
• Adjustable behavior on bus or power failure (configurable per channel)

Note

The device is designed for fixed mounting on a 35 mm DIN rail in dry indoor spaces. It is not permitted to operate mixed nominal and safety extra-low voltages (SELV) within the actuator. All relays maintain their current switching position during a power failure. In the event of bus voltage failure or return, the relay switching positions can be programmed individually for each channel.
