Electrical Connections:
Incoming power for the 100-250V AC powered analyzers is supplied through a universal power entry module. A standard
computer type power cord (P/N A-1008) is required for the universal power entry module. A well grounded insulated power
cable is recommended to avoid noise resulting from unwanted interference.
The appropriate AC power supply (110V or 220V) must specified be specified at order placement if the analyzer is to be
equipped with proper the temperature control heater system.
Power consumption is approximately 150-200 watts with the temperature control heater system and 30 watts without.
Caution: Integral 4-20mA converters are internally powered and do not require external power. DO NOT supply any voltage to
any of the terminals for 4-20mA signal output and range ID or the 4-20mA converters will be damaged.
Caution: To assure proper grounding, connect the 4-20mA signal output to the external device (PLC, DCS, etc.) before
attempting any zero or span adjustments.
Optional Range ID:
The standard 4-20mA output used for range identification, as described below, can be replaced by eliminating the alarms
feature and using the relay contacts associated with the alarms to provide a single common and four (4) normally open relay
contacts that close when the related range is active. The dry contacts are rated at 30VDC @ 1A and powering them is not
required if the PLC can distinguish contact closure via continuity check.
