Analog Master Termination

Features and benefits

16 independently configurable channels supporting:

4 to 20 mADC, 0/1 to +5 VDC, or -10/0 to +10 VDC

Configurable A/D resolution 12 to 16-Bit (with polarity)

22.5 msec update per CH, 180 msec update for all 16 CHs

Accuracy is ±0.1 % of Full Scale Range where FSR = 25 mA or 20 VDC

The EL operating mechanism of the Advac circuit breakers (in all versions) is fitted with a mechanical anti-pumping 

device which prevents re-closing due to either electrical or mechanical commands. 

Should both the closing command and any one of the opening commands (local or remote) be active at the same time, 

there would be a continuous succession of opening and closing operations.

The anti-pumping device avoids this situation, ensuring that each closing operation is only followed 

by a single opening operation and that there is no closing operation after this. 

To obtain a further closing operation, the closing command must be released and then re-launched.

The AI01 Analog Input module processes up to 16 high level, group isolated, Analog Input field signals.

Each channel is independently configurable. FC 221 (I/O Device Definition) sets AI module 

operating parameters and each input channel is configured using FC 222 (Analog Input Channel) to 

set indivdual input channel parameters such as engineering units, High/Low alarm limits, etc. 

The AI01 Analog Input module supports several high level signal ranges.

A/D resolution of each channel is configurable from 12 to 16 bits with polarity. 

The AI01 module has two A/D converters, each with 8 input channels. 

The module will update each configured CH in 22.5 msec, for a total of 180 msec if all 16 channels are configured.

In current mode, the AI01 module provides short circuit protection by limiting current to 96 mA. 

The AI01 module will also detect an open circuit in less than 15 seconds.
