The SAT-1xx-TB1 Breakout Box is used to connect a SatSCADA terminal to power, serial ports, and onboard I/O as shown in the following schematic diagram. The terminal is connected to the breakout box via a multiconductor cable housed in flexible conduit.

See SatSCADA Breakout Box for more details.
The Breakout Box contains a fuse block with 5A fuse supplying the terminal. An additional fuse should be placed between the primary power source and the Breakout Box’s internal fuse to protect the supply cable.
The Breakout Box contains a SAT-1xx-TB1 Breakout Board which provides marked termination blocks.
The SAT-1xx-TB1 Breakout Box is used to terminate the terminal at a convenient location. The Flex Cables flying leads are terminated to the 10 pin terminal block at the top of the breakout board.
The leads are color coded, and should be terminated into the appropriate terminal as per the color named on the breakout board. One unshielded drain wire runs through the flex cable, and should be terminated to the breakout board’s chassis ground. See the individual terminal topics for a table showing the color-coded wire’s functions.

Termination Boards TB1 and TB2 are used to provide easy and simple connection to Power, I/O, and Communication Ports for SAT1XX RTU family. TB1 and TB2 provide color coded terminations of SAT100, SAT110, SAT120, and SAT130 cables and wiring harnesses.
Termination Board TB1 has 4 inputs terminated in individual terminal blocks for each channel. Note that the I/O port channels have common ground terminal (all ports labelled - are connected to common GND).
Termination Board TB2 terminate all I/O wiring from the SAT1xx terminals, however does not supply a individual GND terminal for each channel. TB2 would be used with addition external terminal blocks. TB2 is commonly used when only a single I/O is point is used, or when space is limited.
Fig.1 DI - Digital Input Wiring with TB1 and TB2
Wiring for Digital Inputs (DI) on the SAT1XX is as shown. Digital inputs are normally pulled high with a pullup resistor. A dry contact input will be used to pull the input to the low state.
Fig.2 AI - Analog 4-20mA Current Loop Input Wiring
Wiring for 4-20ma Analog Inputs for SAT1xx RTU’s are as shown. A load resistor RL (133 Ohm) is used to convert the 4-20ma signal to a voltages input voltage. RL can be bridged across the inputs on TB1.
Fig.3 AI - Analog Voltage Input Wiring
Wiring for Analog Voltage Inputs for SAT1xx RTU’s are as shown. The Analog Inputs on the SAT1XX RTU operate in the 0-3 VDC range.
Fig. 4 DO - Digital Output (Relay Contact) Wiring
Digital Output Wiring for SAT1xx RTU’s are as shown. A relay rated for the voltage supply (VSupply) is used to provide dry contact outputs corresponding the digital inputs.
The digital outputs on the SAT1xx can sink 1A continuous at 12VDC and 24VDC.
SCADAlink Single Channel Signal Conditioning Boards provide
SC-VIN - Voltage Input - Provide a Buffered 0-5VDC Input including a a 2.5 VDC Precision Voltage Reference output is provided for potentiometer inputs. The SC-VIN can be used to connect 1-5VDC low power transmitters to SAT1xx RTU’s.
SC-CIN - 4-20 ma Inputs - Provide Buffered and protected 4-20ma Input. A RL of 25 ohm. is provided. VLoop is connect to VSupply can can supply loop power.
SC-DIN Digital Input - digital input provides the following function, signal inversion, LED indication, and and Input Conditioning. LED is used to assist in maintenance and troubleshooting.
