• 4 Fully Adjustable Setpoints
• Better Than ±0.05% Repeatability
• Simple On/Off Control of Process Functions

Multi-Point Process Switch is a single channel analog set-point control. It provides continuous monitoring of a typical process loop with four (4) setpoints that are user adjustable over the full range.

This simple controller or switch module is compatible with any process variable transmitter (i.e., pressure, level, temperature) generating two wire 4-20 mA output. Its four independent setpoints control relays configured as form C (SPDT) can be used to trigger multiple devices, alarms, or provide fail-safe limiting. The switch relay contacts are intended for pilot circuits and rated up to 3 amp service.

Multi-Point Process Switch additionally protects against input circuit overloads using advanced PTC resistor technology and automatically resets when current level drops. This protects the switch and any other loop components against current levels in excess of 70 mAdc (such as dead-short or fault).

• Graphic 10.4" Color LCD Touch Screen HMI
• Supports Continuous Monitoring up to 32 Tanks
• Link Data via Ethernet/IP, Rockwall Automation DF1, or Modbus TCP/IP


A complete integration solution, KING-GAGE® LP3 system unifies data acquisition, HMI display terminals, and networking flexibility for fluid processing operations. Addressing multiple tanks requiring level measurement and inventory monitoring, this system reduces I/O overhead at a PLC or other process control device.

More importantly, by performing the scaling functions independently, it frees up the PLC to focus on the batching and control functions (with register values loaded directly from the LP3 interface). The benefits of this approach include better data integrity and PLC performance optimized toward more critical control functions. The LP3 integral data acquisition function coupled with network connectivity, including Ethernet, simplifies the sharing of tank inventory data across the process floor or throughout a corporate enterprise.

Built-in digital communications capability for Ethernet, USB, RS485, RS232C supports up to 4 high-speed serial ports linking PLCs, SCADA systems, or Internet access (via an integrated web server). Network protocols directly supported by LP3 include Allen-Bradley DF1 over Ethernet and Modbus TCP/IP.

• 8 Tank Multiple Channel Capacity
• Direct Entry of Digital Setpoints
• Dual SPDT Controller Relays per Channel

LP2 SP indicators provide continuous measurement of liquid inventory in storage or processing tanks. Calculating level on the basis of hydrostatic pressure created by liquid depth, the system measures total product mass for more precise material accounting. A full numeric keypad and function keys support various user selections, including direct entry of control setpoints (high or low level) for each tank. The two line alphanumeric LCD readout shows tank level, readout unit (user selective), tank name. and specific gravity in the normal display mode.

The LP2 SP models add functionality of digital setpoints for simple level monitoring and basic control solution for many applications. These indicators support digital RS-485 communications to a central control system while allowing limited local control to production personnel. LP2 SP provides the user with two (2) fully independent SPDT relays per tank input channel. The hardware configuration includes normally-open (NO), normallyclosed (NC), and common (C) relay contacts. Factory programming options include standard LOW-HIGH (descending/ascending) or HIGH-HIGH (ascending/ascending) setpoint actuation.
