Product Description

The IC200ALG630 Analog Input Thermocouple Module is an intelligent
module that accepts seven independent thermocouple or millivolt inputs.

The module receives power from the backplane power supply. No
external power source is required.

Each input channel can be configured to report millivolts ranges as
1/100 of millivolts, or thermocouple inputs as linearized temperature in
tenths of degrees Celsius or Fahrenheit, with or without cold junction
compensation.

The module automatically performs A/D calibration at powerup.
Automatic calibration is then repeated periodically to compensate for
changes in the ambient temperature. New calibration values are filtered
into the current calibration values.

Host Interface

The Analog Input Thermocouple Module uses the following data types:

 7 words of analog input data.
 7 optional words of analog output data.

The module exchanges data in the same manner as other types of I/O
modules: it provides all its input data when requested.

Diagnostics

The Analog Input Thermocouple Module performs diagnostics and
provides the following information.

 Alarm faults are reported if the processed value for a channel

exceeds its configured alarm limit.

 Over/underrange faults are reported if the millivolt value for an

input exceeds the limits of its span.

 Open circuit is checked every time a thermocouple input is read

(unless Open TC checking is disabled). If the circuit is open, a fault
is reported and the input defaults to the configured channel default.

 Thermistor fault will be reported as Internal fault in the I/O Fault

table.

A thermistor fault occurs if the calculated temperature value from the
thermistor is less than -10 °C or greater than +75 °C.

LED Indicators

The green OK LED is on when backplane power is present to the
module. If this LED is amber, it indicates a module fault.

Preinstallation Check

Carefully inspect all shipping containers for damage. If any equipment
is damaged, notify the delivery service immediately. Save the
damaged shipping container for inspection by the delivery service.
After unpacking the equipment, record all serial numbers. Save the
shipping containers and packing material in case it is necessary to
transport or ship any part of the system.

Installation Instructions

The preferred installation technique is to mount the Thermocouple
Module on a Connector-style I/O Carrier and connect thermocouples to
an Interposing Thermocouple Carrier as shown below. The Interposing
Thermocouple-style I/O Carrier provides both box-style wiring terminals
and a built-in thermistor for Local Cold Junction Compensation. It
connects to the Connector-Style Carrier via a cable as shown. This
allows the thermocouple connections to be located away from the I/O
modules in the system. Each TC terminal on the Interposing
Thermocouple Carrier accommodates one solid or stranded AWG #14
(avg. 2.1mm2 cross section) to AWG #22 (avg. 0.36mm2 cross section)
wire, or two wires up to AWG #18 (avg. 0.86mm2 cross section).

However, it is also possible to mount the Thermocouple Module on one
of the terminal-style carriers (box-style, spring-style, or barrier-style) and
provide Local Cold Junction Compensation by using a kit that includes
the correct type of thermistor, as described in the I/O Modules User
Manual. Both methods are shown below. The thermistor kit must be
installed on the A9 and A10 terminals of the carrier.

If the module will only be used to measure millivolt inputs, not
thermocouple inputs, it can be mounted on any type of I/O Carrier. The
thermistor terminals A9 and A10 cannot be used as millivolt input
terminals.
