Input/Output 1 & Output 2
These outputs can be logic (SSR drive), or relay, or mA
dc. In addition the logic output 1 can be used as a
contact closure input.
For input/output functions, see Quick Start Code in
section 4.1.1.
2.7.1
Relay Output (Form A, normally open)
•
Isolated output 240Vac CAT II
•
Contact rating: 2A 264Vac
resistive
2.7.2
Logic (SSR drive) Output

The output switching rate must be set to prevent
damage to the output device in use. See
parameter 1.PLS or 2.PLS in section 5.3.

Remote Setpoint Input
•
There are two inputs; 4-
20mA and 0-10 Volts which
can be fitted in place of
digital communications
•
It is not necessary to fit an
external burden resistor to the 4-20mA input
•
If the 4-20mA remote setpoint input is connected and
valid (>3.5mA; < 22mA) it will be used as the main
setpoint. If it is not valid or not connected the
controller will try to use the Volts input. Volts sensor
break occurs at <-1; >+11V. The two inputs are not
isolated from each other
•
If neither remote input is valid the controller will fall
back to the internal setpoint, SP1 or SP2 and flash the
alarm beacon. The alarm can also be configured to
activate a relay (see section 12.1.1) or read over digital
communications.
•
To calibrate the remote setpoint, if required, see
section 16.3.5
•
A local SP trim value is available in access level 3 (see
section 10.1).
2.9
Output 3
Output 3 is available only in the models 3208, 32h8 and
3204. It will be either a relay or a mA output.
For output functions, see Quick Start Code in section
4.1.1.
