Continuum I/O System Reference
61
The DM-20, Continuum’s Digital Input and Output module, provides high density,
versatile I/O for many control applications. When coupled with the optional DIO-20
Expansion Board, the DM-20 allows you to mix and match up to 20 digital inputs and
outputs. Using standard off-the-shelf digital I/O blocks, the DIO-20 allows the system
designed to meet a wide range of applications, including ON-OFF or pulse-width
modulation (PWM) control of equipment and for switching inductive loads up to 240VAC.
The DM-20 provides 24 VDC power to the DIO-20 via a separate cable assembly.
When used without the DIO-20 Expansion Board, the DM-20 can control any combination
of inputs and outputs, up to a total of 20 per module. The DM-20 can be used to
drive/sense up to 20 LEDs and/or switches on the Continuum enclosure’s door-mounted
GA-40 or GA-80 Graphic Annunciator Panel via an easy-to-use 25-pin cable assembly
and built-in terminal blocks.
