Introducing the E-PDISO16
Overview: E-PDISO16 features
This user's guide contains all of the information you need to connect the E-PDISO16 to your network or
computer and to the external devices you want to control. You can use the E-PDISO16 in your control
applications to switch on and off a variety of devices, such as fans, blowers, pumps, etc.
The E-PDISO16 is a data acquisition Ethernet interface module supported under Microsoft ® Windows ® 2000
and Windows XP.
The E-PDISO16 provides 16 relay outputs and 16 isolated digital inputs. All I/O connections are made to three
sets of screw terminals on the module.
The 16 individual, optically isolated (500 V) digital inputs can be driven by either AC (50 to 1000 Hz) or DC at
levels up to 30 volts. Each input channel has a software-enabled low-pass AC filter with a time constant of 5 ms
(200 Hz). The 16 inputs can be read back as a single byte.
The 16 outputs are single-pole double-throw (SPDT) dry contact, Form-C electromechanical relays. The screw
terminals provide three connections to each relay – normally open (NO), normally closed (NC), and common
(C). The relays are in a non-energized state (NC) upon power up.
The E-PDISO16 is powered by an external +9 V regulated power supply that is shipped with the module. A
power output lets you power additional Measurement Computing products from one external power supply.
Depending on your load requirement, daisy-chained modules may require a separate power supply.
On-board LEDs display the status of communication, external power, and the Ethernet connection. A fourth
LED is used for testing purposes.
The E-PDISO16 is shipped in a rugged metal enclosure that you can mount on a DIN rail or on a bench.
