1.0 GENERAL
PDC series systems are configurable, digital, microprocessor based, controllers for use in non-hazardous (non-explosion rated) environments
for commercial and industrial applications. They are available in several basic configurations. One to eight analog channels, one to sixteen
digital channels, one to thirty-two digital channels, one to sixty-four digital channels, one to ninety-six digital channels, one to one hundred and
twenty-eight digital channels.
NOTE: Only the first eight system channels can be utilized for analog inputs.
A basic system provides one common set of LED indicating lights for “Power”, “Fail”, “Low (Warning) Gas Alarm”, “Mid Gas Alarm, “High Gas
Alarm”, an integral audible alarm with silence push-button, scrolling, backlit, 2-line LCD digital display, eight dry contact relays, user
configurable circuit and RS485, 4-wire “multi-drop” wiring. An eight channel version is also available for use with conventional analog
transmitters.
A good selection of electrochemical, MOS (Metal Oxide Semi-conductor) solid-state, and catalytic sensor / transmitters (digital and analog)
are available for use within the PDC series controllers.
