The optional RS485 multi-drop serial communication interface provides
two-way communication between a TCU unit and other compatible
equipment such as a printer, a p rogrammable controller, or a host computer.
In multi-pointapplications the address number of each uniton the line can be
programmed from zero to ninety nine. Up to thirty-two units can be installed
ona singlepair ofwires. TheSetpointvalue, %Output Power,Setpoint Ramp
Rate, etc. can be interrogated or changed, by sending the proper command
code via serial communications. Alarm output(s) may also be reset via the
serial communications interface option. A programmable User Input is
available with RS485, Valve Position, Heater Current Monitor, and Second
AnalogInput models.The UserInputcan beprogrammedtop erformavariety
of controller f unctions.
An optional NEMA 4X/IP65 rated bezel is available for wash down
applications and similar environments, when properly installed. Modern
surface-mount technology, in-house assembly and testing, and high
immunity to noise interf erence makes the controller extremely reliable in
industrial environments.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in
themanualor onequipmentmust beobservedto ensurepersonal safetyandto
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Do notuse theTCU to directlycommandmotors,valves, orother actuators
notequipped with safeguards.To doso, canbe potentiallyharmfulto persons
or equipment inthe event ofa fault tothe unit.An independent and redundant
temperaturelimit indicatorwith alarmoutputs is stronglyrecommended.The
indicators should have input sensors and AC power feeds independent from
other equipment.
