The CN63500 Series are temperature limit controllers,
intended to provide an independent shutdown for
thermal processes. The CN63500 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. Dual 4-digit displays allow viewing of the
process temperature and limit setpoint simultaneously.
Front panel indicators inform the operator of the
process and output status. The main limit output and
alarm outputs are field-replaceable. The limit output is
selectable for high or low trip activation. If the process
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. Relay alarm(s)
can be configured to activate according to a variety of
actions (absolute high or low, deviation high or low
and band in or out) with adjustable hysteresis. A
standby feature suppresses the alarm during power-up
unit the process stabilizes outside the alarm region.
The unit is constructed of lightweight, high-impact
plastic case with a tinted 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, plush high-immunity to noise
interference makes the CN63500 extremely reliable in
industrial environments.
