GENERAL DESCRIPTION

The isolated 8 channel mA input module DAM8081 is a Din Rail mount I/O Module. The input is mA/mV.

The DAM 8081 converts the analog signal to a 16 bit digital format. The data is transmitted by the MODBUS RTU/ASCII protocol on RS-485 or RS232.

The DAM8081 is equipped with two Watch-Dog timers. In case of alarm, the outputs are forced automatically to a fail safe condition. The digital outputs can also be used as trip alarms of the input analog signal enabling local control.
