Description
Description
The DMD1080 accepts a DCvoltage or current input andprovides visual alarm indicationand alarm relay contact outputs.15 voltage and 9 current inputranges can be field configured viaexternal rotary and slide switches.Offset ranges such as 1 to 5 Vdcand 4 to 20 mAdc are also included.Heavy-duty relay contacts allowthe module to directly control highcapacity loads. Front accessiblepotentiometers are used to adjustthe alarm setpoint from 0 to 100%and the deadband from 1 to 100%.The unit provides a single setpointadjustment of the two DPST relaycontacts. The alarm output canbe field configured for HI or LOoperation, latching or non-latching,and normal or reverse acting.
