Analog Inputs and Analog Outputs

Overview

The rear module is equipped with:

o2 temperature analog inputs (16-bit) configurable

o2 analog inputs (13-bit) configurable

o2 analog outputs (12-bit) configurable

DANGER

FIRE HAZARD

Use only the correct wire sizes for the current capacity of the power supplies.

Failure to follow these instructions will result in death or serious injury.

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not exceed any of the rated values specified in the environmental and electrical characteristics tables.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Analog Features

There are different terminal connection points for each type of analog signal.

Since current and voltage requires different adjustment values, you also need to configure the desired type of input or output signal:

o-10...10 Vdc voltage signal (default).

o0...10 Vdc voltage signal

o0...20 mA current signal.

o4...20 mA current signal.

The temperature measurement values are converted into numeric values that can be processed by the controller. For temperature measurements, the temperature rear module returns the measured value in 0.1 °C (0.18 °F) steps.

The table shows the analog features:

Number and Type of Channels	Digital Converter Resolution	Voltage/Current
2 inputs	12-bit + sign 12-bit	-10...10 Vdc (digital value -4096 to 4095) 0...10 Vdc (digital value 0 to 8192) 0...20 mA (digital value 0 to 8192) 4...20 mA (digital value 0 to 8192)
2 inputs	16-bit	RTD (Resistance Temperature Detector): PT100/1000/NI100/1000 Thermocouple: J, K, R, B, S, T, E, N
2 outputs	12-bit	-10...10 Vdc (digital value -2048 to 2047) 0...10 Vdc (digital value 0 to 4095) 0...20 mA (digital value 0 to 4095) 4...20 mA (digital value 0 to 4095)

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not connect wires to unused terminals and/or terminals indicated as “No Connection (N.C.)”.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING

UNINTENDED EQUIPMENT OPERATION

oUse shielded cables for all fast I/O, analog I/O, and communication signals.

oGround cable shields for all fast I/O, analog I/O, and communication signals at a single point¹.

oRoute communications and I/O cables separately from power cables.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

¹Multipoint grounding is permissible if connections are made to an equipotential ground plane dimensioned to help avoid cable shield damage in the event of power system short-circuit currents.

WARNING

UNINTENDED EQUIPMENT OPERATION

oUse shielded cables for all fast I/O, analog I/O and communication signals.

oGround cable shields for all analog I/O, fast I/O and communication signals at a single point¹.

oRoute communication and I/O cables separately from power cables.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
