9. Specicaons
Universal Input
Strain Gauge: 350 , by means of 4 or 6 wire (6 to use internal Shunt resistor)
Bridge excitaon: 10VDC ± 7% @ 45mA Max.
Bridge Sensivity: 1.4-4mV/V
Shunt Value: From 40%to 100%
Input signal Span: -25% to 125% (Approx. -10mV to +50mV)
Thermocouple ± 0.1% of full range, ±1LSD (±1°C for Thermocouple CJC).
BS4937, NBS125 & IEC584.
PT100 Calibraon: ±0.1% of full range, ±1LSD.
BS1904 & DIN43760 (0.00385 / /°C).
DC Calibraon: ±0.1% of full range, ±1LSD.
Sampling Rate: 4 per second. (250ms)
Impedance: >10M resisve, except DC mA (5 ) and V (47k ).
Sensor Break Strain Gauge: Depending on user seng lnPF can cause input to fail
high scale or low scale reading. Reading will fail on either, Sig+ or Sig-
loss, or incorrect excitaon output <0.8mA and >50mA supply.
Thermocouple/RTD: High alarms acvate for sensor break. Linear 4 to 20mA, 2 to 10V and
1 to 5V DC: Low alarms acvate for sensor break.
Note: Sensor break not detectable on 0 to 20mA, 2 to 10V
and 1 to 5V DC input types.
Isolaon: Isolated from all outputs.
Universal input must not be connected to operator accessible circuits
if single relay outputs are connected to a hazardous voltage source.
Supplementary insulaon or input grounding would then be required.
Logic Input
Input Signal: If the Logic State seng in Cong Mode = CLS, Reset or Tare occurs on
an Open to Closed transion, or high (3 to 5VDC) to low (<0.8VDC)
transion.
If Logic State seng in Cong Mode = OPN, Reset or Tare occurs on a
Closed to Open transion, or low (<0.8VDC) to high (3 to 5VDC))
transion.
Isolaon: No isolaon from inputs and other outputs.
