GENERAL

Microprocessor controller, 48x96 (1/8
DIN) format for model 1000 and 96x96
(1/4 DIN) format for models 1001 and
1101 manufactured using SMT.
The 1000 family of controllers provide a
complete operator interface, with a Lexan
membrane faceplate to give IP54 frontal
protection that has 3 keys, two green
LED displays with 3 (1000) or 4 (1001
and 1101) digits, and red LED indicators
for the 3 alarm relay outputs and a green
LED for the main control output.
The main input for the control variable is
universal and provides the possibility of
connecting different types of signal:
ï Thermocouples of types J, K, N, S, R, T
ï Resistance thermometer Pt100 (3-wire)
ï Linear inputs:
0-50mV, 10-50mV keyboard definable
2-10V, 0-10V, 0-20mA, 4-20mA with an
external shunt.
An auxiliary analogue input is available
for a current transformer input.
The instrument has a double control out­put that is both relay (5A a 250Vac
/30Vdc cos

ϕ

= 1) and static (24Vdc ±
10%, 12Vmin a 20mA) and up to a maxi­mum of 3 alarm relay outputs (5A,
250Vac/30Vdc cos

ϕ

= 1).
Alternatively, the control output can be
analogue (0-20mA, 4-20mA or 0-10V,
2-10V).

The optional communications port can be
Current Loop or RS485 with GEFRAN
(Cencal) protocol with a maximum speed
of 9600 baud (RS485).
The programming of the instrument is
simplified by the grouping of the parame­ters into function blocks.
Access to the configuration parameters is
protected by a hardware jumper and a
protection code can be used to restrict
the number of parameters that can be
displayed and modified by the user.
A PC programming kit is available for
even simpler configuration, composed of
a cable and a guided program for
Windows environment (see data sheet
code WINSTRUM).
