Descrizione

The TX80 Series has been superseded by the TX82B Series

The TX80 series are two-wire current-loop indicators that are powered directly by a 1-5 mA, 4-20 mA or 10-50 mA process loop signal, with a maximum voltage drop of 2.5 V. No separate power supply connections are required. This reduces overall hardware and field wiring costs and provides immunity from most electrical noise encountered in process control environments.

SPECIFICATIONS
Signal: 1-5 mA, 4-20 mA or 10-50 mA (jumper-selectable)
Linear Range: 0.3 to 50 mA
Protection: 200 mA forward, 1000 mA reverse
Forward Voltage Drop: 2.5 V max up to 50 mA
Input Resistance: 50 Ohms at 1-5 mA, 12.5 Ohms at 4-20 mA, 5 Ohms at 10-50 mA
Zero Adjust: -2000 to +2000 counts (4 jumper- selectable ranges plus fine adjustment)
Span Adjust: 0 to 2000 counts (with fine adjustment)
NMR: 46 dB, 50/60 Hz
CMR, Meter to Case: 120 dB, dc to 60 Hz
CMV, Meter to Case: 700 Vp
RFI Susceptibility: Less than ±0.5% of span with conduit fitting or external explosion-proof housing in 10 V/m field strength at 27 or 440 MHz
Accuracy @ 25°C: ±0.1% of span ±1 count
Zero Tempco: ±0.1 count/°C typ, ±0.2 count/°C max
Span Tempco: ±0.005% of span/°C typ, ±0.015% of span/°C max
