SIGNAL CONTROLLER 2286
• Multiple functions
• Programmable from front
• 3-digit LED display
• Analogue or Pt100 input
• Relay outputs
• Max. 50% offset
Applications:
PID on/off controller, PI step controller or 3-band controller with analogue or
Pt100 input. As trip amplifier with setpoint adjustment through external current /
voltage signal with neutral zone surrounding the setpoint. Especially suitable in
applications where easy 11-pole relay socket mounting is required for instance in
a panel. Possibility for readout of process data through the built-in display.
Technical characteristics:
General:
The 2286 is microprocessor-controlled and basic-calibrated. This means that the
input and output can be programmed acc. to the requested signal range without
any re-adjustment. Thereby a high degree of accuracy and flexibility are ensured.
The output consists of two relays with a make contact connected to a common
point. The user interface consists of a 3-digit display and 3 function keys in the
front. The interface is used to change a function or an input signal range.
Inputs:
Analogue inputs - 2286A
The A and B channels can be freely programmed via the front keys and JP1 and
JP2 to current in the range 0...20 mA or voltage in the range 0...10 VDC with a
max. offset of 50% of the actual max. value.
Pt100 input - 2286B
Linearised Pt100 temperature input in the range -99...+850 °C with 3-wire
connection. The temperature range can be scaled via the front keys. Max. offset
is 50% of max. tempera ture, min. span is 50°C.

HOW TO DISMANTLE SYSTEM 2200
Picture 1.
The back panel of the module is
detached from the housing by way of
a screwdriver.
Picture 2.
After this, the back panel can be pulled
out together with the PCB, but
please notice the position of the
PCB as there is a number of different
positions in the house. Do not pull
the wires unnecessarily, instead pull
the PCB. Switches and jumpers can
now be moved. When assembling
the back plate and housing, please
make sure no wires are stuck.
