DP20 Economical Multisignal Meter Instruction Manual
1. Economical mulsignal meter DP20
⅛ DIN Economical Mulsignal panel meter for Process, Temperature and Electrical measurements
Economical mulsignal digital panel meter in ⅛ DIN size for panel
mount, and a wide range of applicaons. Accepts AC and DC voltage
signals from mV up to 600 V and currents up to 5 A (AC measures
in True RMS), process signals (mA and Vdc) with excitaon voltage
included, thermocouples K, J, E, N, L, R, S, B, T and C, resisve
temperature probes (Pt100, Pt500, Pt1000, Ni100, Ni200, Ni1000,
PTC and NTC), resistances, potenometers and frequency. Scalable
reading with 4 digits up to 9999 / -1999 with congurable decimal
point. Two independent alarms, congurable as maximum or
minimum, with hysteresis and setpoint.
Oponal 1 or 2 relay outputs, 4/20 mA isolated analog output, and
Modbus RTU isolated serial communicaons.
Front protecon IP65. Connecons with plug-in screw terminals.

Instrument designed for industrial use, highly exible, allows for
integraon in mulple applicaons, reduced cost, excellent quality
and oponal customizaon available.
• ‘Fast access’ menu at front key UP (5) congurable for fast access
to alarm setpoints (see secon 1.19).
• ‘Eco’ mode reduces power consumpon
(see secon 1.22).
• Simplied scaling conguraon (see secon 1.20).
• Funcon ‘external control’ to acvate with a contact a predened
funcon (second scaling, decimal point, reading “hold”, “tare,“
memory of maximum or minimum) (see secon 1.23).
• 5 congurable brightness levels (see secon 1.28.7).
