1. INTRODUCTION
The series DGN175 offers a complete range of highly accurate
programmable digital panel meters. Each appliance is equipped on front
face with a two-colour 4 digits 14 mm high display, with a brightness which
integrates perfectly in applications in industrial control rooms.
They allow the display, the control and the transmission of data from
any measurable magnitudes.
• The DGN175 U (process inputs) includes as standard:
A bidirectional DC current or voltage input:
±20mA, ±100mV, ±1V, ±10V, ±150V, ±300V.
- Measurable scale overrange from -10% to +10%
- Scale factor programmable
- Enlarging effect
- Extraction of the square root
- Special linearisation in 20 points
- Supply for 2 or 3-wire sensor
• The DGN175 T (temperature input) includes as standard:
A thermocouple input:
(J, K, B, R, S, T, E, N, L, W/G, W3/D, W5/C)
A sensor input: Pt 100 , Ni 100
- Wiring in 2, 3 or 4 wire.
2-wire Pt100 measurement
• The DGN175 M (universal input) includes as standard:
The inputs of the DGN175 U and T plus:
A resistive sensor input: Calibers 0-400 and 0-10 k
A potentiometer input: from 100 to 10 k
