The DMD1080 accepts a DC
voltage or current input and
provides visual alarm indication
and alarm relay contact outputs.
15 voltage and 9 current input
ranges can be field configured via
external rotary and slide switches.
Offset ranges such as 1 to 5 Vdc
and 4 to 20 mAdc are also included.
Heavy-duty relay contacts allow
the module to directly control high
capacity loads. Front accessible
potentiometers are used to adjust
the alarm setpoint from 0 to 100%
and the deadband from 1 to 100%.
The unit provides a single setpoint
adjustment of the two DPST relay
contacts. The alarm output can
be field configured for HI or LO
operation, latching or non-latching,
and normal or reverse acting.
