Model 1223 - 3 channel

The channel module is a stand-alone unit with its own microprocessor, power supplies, alarm relays, self diagnostics and controls. Easy to use and service, each channel module provides self diagnostics that automatically check power supplies, sensors, signal output and connections to insure key components are functioning properly.

Failure codes are provided to quickly locate troubles spots and assist in keeping the system on line at all times. The module can be easily re-configured to operate in the dual detector configuration by simply installing the S2 activation PC board. When installed, the microprocessor automatically reconfigures itself to accommodate the second detector.

Modifications to the channel module settings are protected by an optional pass code which prevents access to the SELECT key menus. Once the SELECT key is activated the menus are displayed. Successive key strokes advance the selection, and menus are prioritized based on anticipated usage.

Options

• T Two sensors per channel
• M 4-20 mADC output
• R RS-485 output (MODBUS Protocol )
• V 12-24 VDc operation

Detectors

Refined over the years, Teledyne’s rugged detector design has demonstrated exceptional performance under the harshest environments. Based on the low temperature catalytic oxidation principle, the detector utilizes stainless steel support bars in the construction of the platinum sensing beads which provide exceptional stability and long life under shock and vibration conditions.

During operation, the beads are heated by a constant current through the heating coils. Oxidation of the combustible gases at the catalytic active bead raises the beads. This temperature rise in turn causes the resistance of the coil to increase. Measurement of the change in the coil resistance produces an accurate measurement of the concentration of the combustible gas. The inert bead compensates for changes in coil resistance which might occur from other phenomena other than the combustible gas.

A wide variety of sensor configurations are available to meet specific application requirements including stainless steel sensor housings, lead or silicone resistance, and
