820 Controller |
|
- Low cost controller for installations up to 2 channels
- Flexible ModBus RTU interface
- 4-20 mA outputs
|
A flexible solution for fixed-point gas monitoring installations,
the 820 Controller is ideal for a wide range of
applications, the 820 Controller can be used for its simple
local monitoring and alarm capabilities as well as in more
elaborate network setups.
Appropriate for both industrial and non-industrial
applications, the two-channel analog controller can
accept one or two 4-20 mA input signals from any gas
transmitter and display the reading on the large LED display.
The 820 Controller offers an easy-to-navigate user
interface for configuration and control of every parameter
including alarm values. The 820 Controller can also be
part of a larger digital network using ModBus Remote
Terminal Unit (RTU) protocol. This interface can facilitate
sensor data sharing and remote operation of the 820
Controller through any ModBus RTU controller. A built-in
signal pass-through feature also allows the values of the
two analog input signals to be sent as two isolated 4-20
mA signals to other PLC or DCS control devices.
Five programmable analog relays are also featured
for alarm and fault conditions. When alarm conditions are
reached, the 820 Controller can control alarms, fans and
horns as well as emit its own audible alarm along with
LED and real-time display notifications.
Compatible with Industrial Scientific’s iTrans and
AirAware fixed-point gas detectors, the 820 Controller
also includes programmable high and low alarm limits for
each input channel, a real-time clock for time-stamping
and date-stamping alarm records, separate alarm record
tables for each input sensor, and a power LED that flashes
when the supply power is above or below the acceptable
range. |
