GENERAL DESCRIPTION
The ITMS4037 Intelligent Temperature to MODBUS™ Conditioner with
Alarms accepts a wide range of temperature sensors (thermocouple and RTD
elements), and converts the signal into a register format that can be read using
either ASCII or RTU MODBUS protocol.
The ITMS allows a choice of either Fahrenheit or Celsius readout with 0.1 or
1 degree of resolution. An offset value can be programmed to scale the input
signal to meet most process requirements. Additionally, two setpoint values can
be entered for dual relay process monitoring alarms.
The ITMS is programmed with Windows™ based SFIMS software. The
software allows configuration, calibration, and storage of ITMS program files.
Additionally, all setup parameters can be interrogated and modified through
MODBUS register and coil commands.
The RS485 port allows the ITMS to be multidropped, with Baud rates up to
38400. The CBPRO007 programming cable converts the RS232 port of a PC to
RS485, and is terminated with an RJ-11 connector. The bidirectional capability
of the CBPRO007 allows it to be used as a permanent interface cable as well as
a programming cable.
The ITMS’s two relay alarms can be configured independently for absolute
high or low acting with balanced or unbalanced hysteresis. Alarm 2 can also be
configured for deviation and band alarms. In these modes, Setpoint 2 tracks
Setpoint 1. Adjustable alarm trip delays can be used for delaying output
response. The alarms can be programmed for Automatic or Latching. Latched
alarms can be reset with a serial command or a user input. A standby feature
suppresses the alarm during power-up until the temperature stabilizes outside
the alarm region. Standby eliminates power-up tripping for low acting alarms.
A user input can be used to set and reset non-latching alarms. The output relays
can also be manually controlled with register commands.
The module’s high density packaging and DIN rail mounting saves time and
panel space. The module is equipped with a universal mounting foot for
attachment to standard DIN rails, including top hat (T) profile or G profile rail.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
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.
