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 in L x 8-1/2in W x 3-3/4 in H) footprint, adjustable voltage (120/230, 50/60 Hz) and simplified wiring provide easy retrofit to existing Fireye® systems.
Fireye® Water Level Control, 4 to 20 mA, For Use With: Nexus PPC6000 or Integrated NX6100 Series of Parallel Positioning Control, Dimensions: 6.3 in L x 3.93 in W
| Amperage Rating | : | 4 to 20 mA |
| Dimensions | : | 6.3 in L x 3.93 in W |
| Suitable For Use With | : | Nexus PPC6000 or Integrated NX6100 Series of Parallel Positioning Control |
- One, two or three element boiler water level control via 4 to 20mA inputs from field devices, feed pump VFD and pump sequencing is also included
- Built-in sequence draft control controls the boiler outlet damper through pre-purge, light off and operation reducing standby and operating losses
- Industry standard TDS probe provides the option to control surface blowdown based on TDS levels set by operators
- Utilize proven Fireye® CANbus servomotors or industrial 4 to 20mA current or I/P feedwater valves
- 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
- Proven hardware with more than five years of in field service has been reconfigured to provide these additional features
