- Can be used with the full range of Status Scientific Controls fixed gas detector heads - certified types require use of an integral safety barrier.
- Graphical displays with backlight with the ability to display trend data in graphical form.
- Menu selection via push buttons on front panel.
- Integral audble alarm.
- Integral sealed lead-acid standby battery.
- Integral safety barrier option for each channel.
- 3 control relays per channel - Alarm Level 1, Alarm Level 2 and Fault.
- Common alarm relay outputs to power external equipment.
- Lockable door.
- Water and dust proof to IP66.
- Compatible with industry standard gas detectors and other sensors.
Description
Although
primarily designed for use with the Status Scientific
Controls range of fixed gas detectors,
the MCU4 Monitoring and Control Unit
provides facilities to accept up to
16 individual inputs from various types
of monitoring instruments or transducers.
A graphical display is provided to
show the status of each channel, display
graphs and enable configuration of
the unit (e.g. set the alarm levels,
program the output relay voting etc.).
The unit can be programmed on-site
by the user using the password protected
configuarion facility. Each monitoring
channel provides relay contact outputs
together with 4 to 20mA and voltage
outputs. Data logging of each channel
is provided as standard.
Internal Safety Barrier
For applications where the gas detector heads (or other sensor type) are sited in a potentially explosive atmosphere, a safety barrier must be fitted to each individual channel in order to limit the maximum voltage and current under a fault condition (e.g. short circuit) such that an incendive spark cannot be created. Where suitable*, the internal safety barrier shown above may be fitted to each of the required channels within the control unit. This can either be fitted at the time of manufacture (where requested) or at a later time if the system is extended by the installation of additional detectors.
*Note that some installations may neccessitate the use of external barriers sited at the safe area/hazardous area interface - see the accessories page.
