Overview

Accura 2350-TEMP module provides data on the internal and external temperature
and internal humidity of industrial control panels.

An event occurs when the internal/external temperature or the temperature difference
rises above the set threshold.

When an event occurs in Accura 2350-TEMP module, the EVENT LED on the front of the module blinks.

When an event occurs in Accura TSEN/THSEN device, the Red LED on the front of the device
blinks.(The Green LED is on during normal operation.)

Internal temperature events are reset with the RESET button on Accura TSEN/THSEN.

Up to 6 Accura TSEN/THSEN devices can be connected to Accura 2350-TEMP module
using the communication cable² up to 100 m¹ long.

The module supports 1 digital input channel and 1 digital output channel.

1. It indicates the maximum cable length between Accura 2350-TEMP and Accura TSEN/THSEN
when Accura 2350-TEMP is the first module connected to Accura 2300[S].
2. The communication cables used to connect Accura 2350-TEMP to Accura TSEN/THSEN are not provided.
