GENERAL DESCRIPTION
provide an independent shutdown for thermal processes. The TLA accepts
signals from a variety of temperature sensors (thermocouple or RTD elements),
and its comprehensive programming allows it to meet a wide variety of
application requirements.

process and output status. The main limit output and alarm outputs are field
replaceable.
temperature goes above the limit setpoint for a high trip, or below the limit
setpoint for a low trip, the limit relay will de-energize to initiate a process
shutdown. The limit output cannot be reset until the process temperature returns
to the proper operating range; manual reset is required (local or remote). Sensor
failure will initiate a process shutdown.

hysteresis. A standby feature suppresses the alarm during power-up until the
process stabilizes outside the alarm region.
front panel. The front panel meets NEMA 4X/IP65 specifications when properly
installed. Multiple units can be stacked horizontally or vertically. Modern
surface-mount technology, extensive testing, plus high immunity to noise
interference makes the TLA extremely reliable in industrial environments.
