11.. . APPENDIX A: MASTER ICON REFERENCE

USING THE OMP-MODL 11-15

THERMISTOR INPUT ICON (MLIM-4)

FUNCTION:

RTD, resistance, and thermistor signal inputs can all be handled with the MLIM-4. With

the MLIM-4 installed in a OMP-MODL, these respective function icons become available

for use in Program Nets.

As a thermistor input, the icon samples the resistance of the connected thermistor,

converts it to temperature and passes it along to the next icon. As thermistors have high

ohm/C ratios, lead wire error is negligible and only the 2-wire configuration is supported.

This channel/icon can be changed to an RTD or resistance input channel by selecting the

Change button.

INPUTS:

Hardware: No signal input shown on icon for Program Net connections.

Update: The input is sampled every time an Update command is received on the

Update input and the Enable terminal is True.

Enable: Processing of the icon is allowed when Enable pin is unconnected or

connected and the Enable signal is TRUE.

OUTPUTS:

Output Signal: Data type signal. The Units of the output are degrees C or F,

selectable from the icon configuration dialog box.
