DI-10: AC or DC Input, 16 Channel

11.3.1 Overview

• Frequency/Pulse/Quadrature counters on up to 7 inputs or input pairs
• Isolated DC Field Power Output
• Software Debounce
• AC or DC Inputs
• Sequence of events recording (with optional GPS time synchronisation)
• Hot Swappable
The DI-10 provides 16 AC or DC input channels allowing it to interface a wide range of input
devices to your RTU. Inputs can be powered by the module's own +12 V
Power or from external AC or DC power sources.
Applying a high positive or AC input voltage results in a logical '1' in the status register, no or
low input voltage results in a logical '0'. Negative DC input voltages cannot be used with
DI-10 modules.
The DI-10 features software configurable pre-conditioning of inputs such as debounce filters,
channel inversion and sequence-of-event recording selectable on any channel(s).
The DI-10 can also perform frequency, pulse or quadrature counting for up to 7 input
channels (or pairs of input channels for quadrature counters).
DI-10 modules can be swapped while RTU is running without causing RTU restart. Inputs
are cleared in RTU memory while module is removed.

Electrical Hazards
Only appropriately qualified and trained personnel can install and
service this equipment.
Always power down input voltages exceeding Safety Extra Low
Voltage (SELV) levels (DC 60 V or AC 42 V
earth and/or ground) before performing any operation on this
product, including field wiring.
Failure to do so may cause fire and may result in a serious
personnel injury or even death.
