5511 UNIVERSAL INDICATOR

Input types:

Thermocouple input: (TC) with 15 bit bipolar resolution for standard thermocouples in the temperature ranges acc. to the IEC 584, the DIN 43710 or ASTM E988-90 standards. The CJC-function is implemented with a Pt100 sensor in the terminal (option - type no. 5911), external Pt100 sensor or fixed CJC (thermostat box). Sensor error detection available.

Current input in ranges with a 15 bit bipolar resolution for DC-current signals. 0% and 100% process calibration is possible with the function keys directly from the front cover. Cable breakage detection available on 4...20 mA signals.

Voltage input in ranges with a 15 bit bipolar resolution for DC-voltage signals, 3-wire potentiometer, load cells, pressure transducers etc. 0% and 100% process calibration is possible with the function keys directly from the front cover.

Auxiliary supplies: (Selected by internal dipswitches).

Loop supply 20 VDC/20 mA for supply of 2-wire transmitter.

Reference voltage 2.5 VDC, 15 mA as reference for 3-wire potentiometers e.g. as position indicator from analogue valves etc.

Excitation voltage 8 VDC, 25 mA for supply of load cells, pressure transducers etc.

Outputs: (option) (Selected by internal dipswitches).

Current output with 13 bit bipolar resolution programmable in the range ±20 mA by a maximum offset of 75% of max. output value.

Voltage output with 13 bit bipolar resolution in the ranges ±1 VDC and ±10 VDC. Max. load 20 mA.

Relay output (relay 1 and 2) is selected as a make or break function. The relays can be used as trip amplifier or/and sensor/cable error alarm for a TC, an RTD, a resistance input and current input.

Display: 41/2 digit LCD or LED display with 14 mm digit height. Max. display readout ±19999 with selectable decimal point, relay ON/OFF-indication and tendency readout for the input signal. From the function keys in the front it is possible to change the limit values and delay for relays, display updating time, display scaling, decimal point, resolution on the last digit, analogue output scaling and calibration of cable resistance. The LCD display has further bargraph indication and the light intensity of the LED display can be changed.
