TM5SAI2PH and TM5SAI4PH

Introduction

The TM5SAI2PH and TM5SAI4PH expansion electronic modules are Analog Resistor Temperature electronic modules with 2 and 4 Inputs respectively.

NOTICE

INOPERABLE EQUIPMENT

Verify that the physical wiring of the analog circuit is compatible with the software configuration for the analog channel.

Failure to follow these instructions can result in equipment damage.

For further information, refer to the Hardware Guide:

Reference	Refer to

Analog Inputs

The converted analog values are output by the electronic module in the registers. Different resistance or temperature measurements result in different value ranges and data types.

Timing Setting

The timing setting for data acquisition is made using the converter hardware. All activated inputs are converted during each conversion cycle.

Conversion Time

The conversion time for the channels depends on their use. For the formulas listed in the table, 'n' corresponds to the number of channels that are agitated.

Channel Uses	Conversion Time
1 channel	1 x Input Filter time
n channels with the same sensor type	n x (Input Filter time + 20 ms)
n channels with different sensor types	n x (2 x Input Filter time + 20 ms)

Reduce Conversion Time

If an input is not necessary, it can be deactivated by setting the sensor type to Off, thereby reducing the refresh time.

The time saved is: Timesaving = 2 x 20 ms + Input Filter time

The Input Filter time is the conversion time for the remaining channels.

Sensor Type and Channel Deactivation

The electronic module is designed for temperature and resistance measurement. The sensor type must be specified because of the different adjustment values for temperature and resistance. To save time, individual channels can be deactivated by setting the sensor type to Off.

This table shows the sensor types:

Sensor Types	Digital Value	Temperature °C (°F)	Resolution
Sensor type PT100	-2000...8500	-200...850 (-328...1562)	0.1°C(0.18°F)
Sensor type PT1000	-2000...8500	-200...850 (-328...1562)	0.1°C (0.18°F)
Resistance measurement 0.1...4500 Ohm	1...45000	–	0.1 Ohm
Resistance measurement 0.05...2250 Ohm	1...45000	–	0.05 Ohm

Limit Analog Value

In addition to the status information, the analog value is set to the values listed below, by default, when a detected error occurs. The analog value is limited to the new values if the limit values were changed.
