A: standardised 1/4 DIN housing (92x92 mm) with seal, to
be built into and attached to the door of the electrical switch
housing or cabinet using 4 locking systems.
B: a main board (identified by "M0:MAIN" on the rear plate) :
• used to connect the electrical power source of the
multiCELL;
• used to power another device, e.g. a flow-rate sensor;
• offering 2 digital inputs (identified by "DI", digital input),
two 4-20 mA current outputs (identified by "AO", analogue
output) and 2 digital outputs (identified by "DO", digital
output).
C: 1 to 6 slots for placing the following modules:
• module with light grey connector for connection of a pH or
oxidation reduction potential sensor and/or a temperature
sensor
• module with green connector for connection of a conductivity
sensor and/or a temperature sensor
• module with black connector with two 4-20 mA current
outputs and 2 digital outputs.
• module with orange connector with two analogue inputs and
2 digital inputs.
D: functional ground screw (connected internally to all "FE"
terminals on the main board and additional modules).
E: memory card (SD type) reader/recorder
