Honeywell 10102/2/1 Fail-safe analog input module (4 channels)

Description:

The fail-safe analog input module 10102/2/1 is equipped with four 0-2 V analog input channels. These analog inputs share a common 0 V connection but are galvanically isolated from the 24 Vdc and 5 Vdc supplies.

The analog inputs can be used actively, with each input having a separate 26 Vdc, > 20 mA short-circuit protected output, or passively, where the supply is directly connected to the transmitter.

The input stage of 10102/2/1 features a high input impedance, allowing the connection of two 10102/2/1 modules in parallel. However, each input requires an analog input converter module 10102/A/ (refer to the 10102/A/ data sheets).

Note: As the inputs require a 10102/A/ converter module, the 10102/2/1 module can only be used in combination with an I/O backplane in the rack.

The analog input module performs scans on the analog inputs, the 26 V output voltages, internal supply voltages, and a reference voltage generated by a D/A converter. This D/A converter generates various reference voltages used to comprehensively test the analog input module. The self-test includes a leakage test of the input filter, which could affect the accuracy of the analog input value.

Within the configured process safety time, the analog inputs are tested for:

Absolute accuracy
Correct conversion over the full range
Crosstalk between inputs
Output voltage of the 26 Vdc outputs

The 26 Vdc outputs are generated by the DC/DC converter and stabilized at 26 Vdc, making them independent of the incoming 24 Vdc supply.

Note: The maximum output current is at least 21 mA. If the transmitters require a higher supply current, the input channel must be used in passive mode (= external supply).

Analog Input Ranges for FSC:

Table 1 provides an overview of the analog input ranges for the FSC system and how the 10102/2/1 module can be used for each of these ranges.

Table 1: Overview of analog inputs for FSC

0(4)-20 mA Internal power: 10102/2/1 + 10102/A/1
0(4)-20 mA External power: 10102/2/1 + 10102/A/2
0(1)-5 V External power: 10102/2/1 + 10102/A/3
0(2)-10 V External power: 10102/2/1 + 10102/A/4
Loop-monitored digital input: 10102/2/1 + 10102/A/5

Other analog input signals such as thermocouples, PT-100, etc., can only be used after conversion to one of the analog input ranges that the FSC system can handle.
