1. OVERVIEW
1.1 Introduction to model DM4500U
The DM4500U model is a digital multifunction instrument which
allows the user to program the input as a:
- PROCESS INPUT (V, mA)
- LOAD CELL INPUT (mV)
- Pt100 INPUT
- THERMOCOUPLE INPUT (J, K, T)
The basic instrument is a soldered assembly composed of a main
board, a
tricolor
programmable display
and a power circuit.
Standard features of the basic instrument include the reading of the
input variable as well as remote hold, reading and memorisation of
max and min values (peak/ valley), tare and reset function, and a
full complement of programmable logic functions.
In addition, a variety of
output
options can be installed at the
factory from the list below :
COMMUNICATION
OPT4500/485
Serial RS485
CONTROL
OPT4500/mA
Analogue (4 to 20) mA
OPT4500/V
Analogue (0 to 10) V
OPT4500/2R
(2 x Relays SPDT 8A)
OPT4500/4R (
4 Relays SPST 5A)
OPT4500/NPN
(4 NPN output)
OPT4500/PNP
(4 PNP output)
All the output options are opto isolated from input signal and power
supply.
This instrument conforms to the following community
standards: 89/336/CEE and 73/23/CEE
Warning: Refer to the instruction manual to preserve
