3. Introduction and Specifications

The all-in-one Digital Amplifier DAD 141.1 is a universal device for any weighing, filling or loss-in-weight

operation and for force measurements with strain gage sensors. The DAD141 is for DIN (TS35) rail mount.

To grant the quality and allow legal weighing the DAD141.1 is OIML R-76 approved (pending) and meet the

MID E2 requirements to EMC.

The standard device includes all the communication facilities needed for industrial weighing, control and

registration, i.e. analog current or voltage output (0/4…20 mA, 0…5V, 0…10V, -5V…+5V and -10V…+10V),

Ethernet, RS 422/485 and logic I/O’s for direct control of valves or bars etc.

The device can be controlled either by the front keys, via RS 422/485 port or Ethernet port. 2 logic inputs and 3

logic outputs make complex control functions easy. The 3 logic outputs can be controlled external, too.

The device features fullfills multi-drop communications capability and can be programmed via a straightforward

ASCII command set. You can connect up to 32 DAD 141.1onto a single RS485 bus.
