ARDETEM DIP 400 - 1. INTRODUCTION

p2
The series DIP 40- offers a complete range of highly accurate program-
mable digital panel meters. Each instrument is equipped on front face
with a five 14mm high red digits display whose brightness suits applica-
tions in industrial control rooms perfectly.
They allow the display, the checking and transmission of data from any
measurable magnitudes.
• The DIP 400 (process inputs) includes in standard:
A DC current or voltage input
Bidirectionnal ±100mV, ±1V, ±10V, ±300V, ±20mA.
- Accuracy: 0.1% of the full scale at +25°C
Thermic drift < 150 ppm/°C
- Measurable scale overstepping from -10% to +10%
- Scale factor programmable
- Enlarging effect - Square root extraction
- Special linearisation on 20 points
- Supply for 2 or 3 wire sensor 24 VDC (±15%) -25 mA
protected from short circuits
• The DIP 401 (temperature input) includes as standard:
Either a thermocouple input:
(J, K, N, S, B, W5, T, R, E, W, W3, L)
- Accuracy: 0.1% of the full scale at +25°C,
or 30µV typical (60µV max.)
- Thermic drift < 150ppm/°C
CJC efficiency: < 0.03°C/°C ± 0.5°C from -5°C to +55°C
Or a sensor input: Pt 100 Ω, Ni 100 Ω
- Line resistance influence in 3 wire measure within the class
for 0<Rl<25Ω
- Measurement of 2 wire ∆ Pt100 from -200°C to +270°C (0<Rl<10Ω)
(R max. 400Ω)
- Max. measure current: 250 µA
- Accuracy: 0.1% of the full scale at +25°C
- thermic drift < 150ppm/°C.
