Hardware Installation
Inputs
Connect the inputs to the iPIO-8 using the screw terminals.
Inputs can be either dry relay or switch contacts, or a +VDC
voltage (3 to 30 V), referenced to a common ground.
Screw terminals are removable for easy installation.
Terminals for each circuit are marked + and G. When
connecting dry relay contacts, the polarity is not significant.
The iPIO-8 is Factory set for Dry Contact Input Only.
Prior to Connecting +VDC, Resistor Pack PU2 must be removed.
Contact Dataprobe Technical Support for Details
When connecting +VDC, connect the positive voltage to the
terminal marked + and the negative or ground to the
terminal marked G.
Status Dry Relay DC Voltage
Open Open >3VDC
Closed Closed <=0VDC
Input Specification
Dry Contact (common ground)
or Wet ±30VDC Max
Relays
Connect to the iPIO-8 relays using the screw terminals, as illustrated. Relays are Form C. Connect to
the Common (C), Normally Closed (NC) and Normally Open (NO) as marked. When the iPIO-8 relay is
in the Open Condition, the Common is connected to the Normally Open. In the Closed state, the
Common and Normally Closed are connected.

Switching Higher Current
The ELK-912-
2 is a two relay board to provide higher current switching for several of Dataprobe’s
remote control products. Each ELK-912-2 is two independent relays, each with screw terminal
connections. The relay boards can be separated in to individual relays as required for mounting.
To use the ELK-912-2 with the iPIO-8, connect the relay board to the Output connections of the iPIO-8
as shown below.
