oxygen connectable (e.g. 8 AEM with 8 detectors each)
Power supply for detectors 24 Vdc (by regulated power supply)
Power consumption for detectors maximum 3,5 VA / 150 mA (per detector)
Signal inputs
- standard 4-20 mA (by AEM), 2 or 3 wire, current
base load (R
in
= 200 Ω + 4300 / I
(mA))
drift < 0.1% upper range value/month
- RS485 (by LOOPM)
Signal processing
digital, 2 redundant 16 bit controllers with cycle time
t
Z
< 100 ms
Display and operation:
Status information
- 7 LEDs per channel for operation, alarm and fault (on
LED module)
- system LEDs (on LCD-/Logo module)
Display
- LCD display for display of gas concentration and
menu operation (on LCD module)
Operation
- 1 button per channel (on LED module)
- 4 buttons for menu operation (on LCD module)
Housing:
Types of housing
wall-mounted housing, 19"-rack with mounting plate
or control panel with mounting plate
Dimensions and weight depends on device configuration
Material (wall-mounted housing) sheet steel (1.5 mm), powder-coated (RAL 7032)
Enclosure rating (wall-mounted
housing)
IP 40 (optional IP 54)
Power supply:
Supply voltage
230 Vac, 50 Hz or
24 Vdc (19,2 to 27,6 Vdc)
Power consumption
depends on system configuration and the amount and
consumption of the connected detectors
Environmental conditions:
Temperature
operation: 0 °C to +55 °C
storage: -25 °C to +60 °C
Humidity 5% to 90% Rh
Pressure 80 to 120 Kpa
Vibration
10 to 55 Hz, maximum amplitude of 0,15 mm
to avoid false alarms on the relay contacts the relay
modules have to be installed vibration-free
Alarms, outputs and communication:
Alarms
- 5 programmable Alarm levels (US, Alarm 1 -3, OS)
and fault per channel
- actual and average alarms configurable
- AND, OR and VOTING function
Relay outputs
- up to 128 free-programmable charge over relay
contacts (on 8 RBM / REM with 16 relay each)
- resistive load: 250 Vac, 6 A
