Gateway Product Versions.
The hub cards indicated can be purchased as ‘Gateways’. These are used in applications where it
is desirable to build gas detection into systems where local displays and alarms are not required.
Examples include OEM equipment, ventilation control and similar. In these applications the hub
card is supplied on its own DIN rail base ready for integration. When using gateways a suitably
sized DIN rail PSU should be used which is dedicated just to the gateway. The PSU must not be
shared with other systems that may interfere to the detriment of the gateway. Power supplies
should be nominally 24V DC adjusted to 27V DC. This is the same for DIN rail mounted versions
of the TOC-750 HUB card
