The 32h8i indicator offers accurate indication and alarming of temperature and process measurements. Process interlocks, including over temperature furnace limits, are implemented using relay output channels.

The emphasis is on ease of use. A simple ‘QuickStart’ code is used to configure all the functions essential for indication and protecting your process. This includes input sensor type, measurement range and alarms making ‘Out of the Box’ operation truly achieveable.

In operator mode every parameter has a scrolling text message describing its function and is available in English, German, French, Spanish or Italian.  More advanced features are configured using iTools with a PC based configuration wizard – giving an easy to use, instructive guide to all the functions in the indicator.


Recipes can be created using the PC tool. These recipes can be used to change the operating parameters of the 3200i simply by selecting the relevant recipe via the 3200i front panel push buttons.

Analogue Retransmission

The measured process value can be retransmitted as either a mA or voltage signal with a selection of outputs including 4-20mA and 0-10Vdc. In the 32h8i this signal is isolated from all other electronics within the unit.

Digital Communication

All units support both EIA232 and EIA485 communication using the Modbus protocol as a slave device. It is also possible to digitally retransmit one parameter using a Modbus broadcast to all other Modbus devices on the network.

Process alarms

Four internal alarm setpoints are provided. They can be used to energise up to three relay outputs, which can be latched if required. A special mode, known as ‘Alarm Blocking’, is available which ensures that when the unit is powered up an alarm must first enter a good state before the alarm becomes active. This is particularly useful for low alarms which can be blocked while the process is warming up.
