2. Product Overview

Description

The TCU800 is a highly integrated pump controller running an embedded Linux operating system. It is designed to 
be backward compatible with its predecessor (TCU001) while including additional feature enhancements to expand its 
operability. 

There are several options for using the TCU’s multiple input/output (I/O) points:

• 

They can be used in the default pump control application. 

• 

They can be used with custom logic (i.e. Ladder logic). Contact DFS for more information. 

Additionally, the TCU: 

• 

Can communicate with and manipulate the I/O points of up to 15 remote modules via a radio or network link. 

• 

Can be incorporated into a Remote Terminal Unit (RTU) by using a Bus Extender Module (BEM). 

The default pump control application program enables the TCU to be easily implemented in lift station or storage tank 
applications. The TCU contains all the hardware and software needed to control up to three motor starters.  

Placing custom logic on the TCU enables it to perform a variety of automated tasks when interfaced with other telemetry 
Modbus-capable devices and equipment (DFS equipment or other devices using RS-485 or RS-232). Custom logic can 

Hand-Off-Auto switches

Connectorized terminals P2 & P4

Receive & transmit LEDs

Power/Home button

LCD touchscreen display

Connectorized terminals P1 & P3

Two USB ports (service port)

Ground screw

Alarm LED
