Features:

The DI-10 provides 16 input points in one group with common power for field contacts. The inputs are designed for wide ranging DC and AC input signals from external devices. Input characteristics are compatible with a wide range of user-supplied input devices, such as: push buttons, limit switches and electronic proximity switches.

The DI-10 module provides all the functionality of the DI-1 and DI-5 modules except the field voltage polarity cannot be reversed. It has software configurable debounce filters, channel inversion and Sequence-of-Events recording selectable on any channel(s). Frequency, pulse or quadrature counting can also be configured for any 7 input channels.

The first 4 channels are high speed inputs, capable of counting up to 10 kHz; the other 12 inputs can count up to 1 kHz. The DI-10 module has 7 user-configurable counter inputs, which appear as 16-bit unsigned integer values in the analog input registers.

Configurable Functions

The first 4 channels are high speed inputs, capable of counting up to 10 kHz; the other 12 inputs can count up to 1 kHz. The DI-10 module has 7 user-configurable counter inputs, which appear as 16-bit unsigned integer values in the analog input registers. These can each be configured as frequency counters for any input channel to 1 Hz resolution, or pulse counters, or quadrature counters which work with quadrature inputs on pairs of channels. Channel inversion can be configured on any input channels. Normally a high voltage level applied to a digital input channel will result in a logical 1 state in the digital input register, and the LED on the front panel of the module being set ON. A low voltage level will result in a logical 0 state in the digital input register, and the LED will be OFF. By configuring channel inversion, the situation is reversed: a high voltage level results in a logical 0 state and the LED is set OFF; a low voltage level results in a logical 1 state and the LED is set ON.

Software Debounce Filters can be configured for any input channel, with a time constant from 1 millisecond to 250 milliseconds. When using AC inputs, the input channels must be configured with a debounce filter of 'AC Filter'.

Sequence-of-Events Recording

Sequence-of-Events (SoE) recording can be configured for any input channel. When SoE is enabled, any event (change of state) on the input channel is logged to 1 millisecond accuracy. This event is automatically included in the Event Log of the RTU. The DI-10 module has a timer that is automatically synchronised with the real-time clock of the processor module.

The DI-10 module has an internal buffer with enough space for 1000 events. The DI-10 module can therefore cope with bursts of up to 1000 events at a time. Events are uploaded into the processor module at a maximum rate of 100 events per second allowing the DI-10 module to cope with events at a sustained rate of 100 events per second.
