MLIM-4; RTD / RESISTANCE INTERFACE MODULE OVERVIEW

Overview

The MLIM-4 is a four channel Interface Module for use in the OMP-MODL System Base. Each of the four channels can be individually programmed for any combination of RTD (100 ohm or 1000 ohm), Resistance or Thermistor input via the HyperWare software (HyperNet).

Additionally, for RTD and resistance measurements, 2, 3, and 4-Wire configurations can be selected. With 3 and 4-wire configurations, the resistance due to the extension wires is minimized. With 3 or 4-wire configuration, each sensor connection will require two input channels.

Module Installation:

Refer to the Installation Section earlier in this chapter for detailed installation instructions of the Interface Module onto the System Base.

I/O Module Layer Requirements / Limitations:

The MLIM-1 module can be installed in any of the five I/O Module positions (Figure 3... -4). The module layer address must be set on the module to correspond to the layer position into which the module is installed.

This address is programmed into the module through the use of the three Module Address Switch banks (Figure 3... -26 and Figure 3... -27). Each switch bank contains 5 switches. Note the marking on the circuit board identifying address rows for Module Layers 2 through 5. Set one switch in each of the 3 banks ON corresponding to a module layer determined above.
