To Connect a Modbus Device to the TB1 Block
The TS4000H TB1 terminal block supports signals for two Modbus channels. You can attach
cabling to connect these signals to Modbus-compatible devices in a control room using the
TS4000H signal pin outs shown in the following table:

To Connect a Device for Remote Calibration or Relay Reset to the TB1 Block
Connectors TB1-6 and TB1-7 can be cabled to a separate device to provide the ability to
remotely calibrate the TS4000H and reset the TS4000H relays. To view the TS4000H LED
display and use the remote calibration switch effectively, the device must be mounted within
view of the display.

3.5.5 Connecting to the +24 VDC Power Supply
The TS4000H operates on +24 VDC power. You must connect the TS4000H to a primary DC
power source.
For Information on the maximum distance between the TS4000H and the control room
equipment, refer to Section 9.5. Each cable run should be as short as possible.
WARNING:
To protect the system from shorting, and to ensure the safety of installation
personnel, the T24 VDC wire must be the
last
wire connected and the
first
wire disconnected. In addition, the power supply
must
remain
OFF
until all
other cabling has been completed; refer to the power supply manual for
instructions.
NOTE:
The TS4000H is designed to continuously monitor the presence of hazardous gas
leaks. A power switch is not included for the TS4000H to prevent accidental system
shut down. Powering the system on and off is done from the power supply. An internal
diode protects the TS4000H in the event of inadvertent power supply reversal.
