NXEXP300 Fireye Water Level Control

Datasheet

Datasheet

The NXEXP300 expands the capability of the parallel positioning system by adding valuable safety-rated digital inputs, sequence draft control, boiler water level control and total dissolved solids (TDS) surface and bottom blowdown control. The small (5” L x 8.5” W x 3.75H) footprint, adjustable voltage (120/230, 50/60 hz.) and simplified wiring provide easy retrofit to existing Fireye systems.

Benefits:

Boiler Water Level	One, two or three-element boiler water level control via 4-20mA inputs from field devices. Feed pump VFD and pump sequencing is also included.
Sequence Draft Control	Built-in sequence draft control controls the boiler outlet damper through pre-purge, light off and operation reducing standby and operating losses.
Total Dissolved Solids	Industry-standard TDS probe provides the option to control surface blowdown based on TDS levels set by operators.
Flexibility	Utilize proven Fireye CANbus servomotors or industrial 4-20mA current or I/P feedwater valves.
Wiring	International voltage setting and simple four-wire CANbus interconnections make wiring a snap. Safety relay contacts can be easily inserted into the existing control wiring.
Reliable Operation	Proven hardware with more than five years of in-field service has been reconfigured to provide these additional features.
