SIGNAL CONDITIONING & ISOLATION THERMOCOUPLE- LINEARIZED O/P

Product Overview The Sensor Signal Conditioner type 4.0-LTCI-XX is a Programmable Thermocouple (TC) Interface Unit with Diagnostic and Alarm capability. The unit can be programmed to interface to standard Thermocouple types J, K, B, E, R, S, T, & N. Thermocouple Temperature ranges for Full Scale output signal are selectable to obtain maximum resolution of the analog output signals. This unit performs the function of converting a TC signal into Single or Dual Isolated and Linerarized 4-20mA output signals. Complex software algorithms ensure very good stability and linearity levels of 0.1% of FS are achieved over the entire input range. In-built Cold Junction Compensation (CJC) facility is provided. The user has the option to ENABLE/DISABLE the CJC function in the analog output of the module. The unit incorporates an additional Diagnostic feature of “SENSOR FAULT (SF)” detection and ALARM output. The in-built unique sensor checking circuit performs a periodic Health Check operation to detect sensor fault. When a fault condition is detected it activates the “SF” indication (Red LED) on the front panel on the module. A logic output signal (24VDC) is also provided by the module which is used as an Alarm signal to warn an external control system about Sensor Fault condition. Additionally a DIP switch is provided to allow the user to select the output signal value set by the module in case of a Sensor Fault condition. The following options are selectable, a. b. c. d.

UPSCALE on Sensor Fault i.e. O/P > 22mA. DOWNSCALE on Sensor Fault i.e. O/P< 3.6mA. HOLD LAST VALUE on Sensor Fault. Do nothing. i.e. Output will follow Input (0mA on Sensor Fault.)

In a Dual output type unit, both the outputs can be individually set by the user to be set to any of the above values in case of SENSOR FAULT condition. Output Wire Break (WB) indications are also provided on the unit. This will indicate 4-20mA Output Open Circuit condition or load resistance >1KOhm across output. Other LED indications provided on the unit are, Input UNDERRANGE (UR), OVERRANGE (OR), & SYSTEM HEALTH (SH).
