The ProtEX PD6830X is an explosion-proof, RS485 serial input Modbus® RTU scanner capable of scanning up to 16 Modbus variables and displaying them on an easy-to-read, dual-line, LCD display.
This Modbus scanner can be programmed as a Modbus RTU master, slave, or snooper. The PD6830X is available in two upper display line configurations: 5-digit decimal display and feet & inches display with bar graph. The lower line is the same for both versions and consists of seven alphanumeric characters.
Like all ProtEX products, the PD6830 carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. Two features that really make the PD6830X stand out are its wide viewing angle display and SafeTouch® through-glass buttons. These buttons allow the PD6830X to be programmed and operated through the glass, thus eliminating the need to remove the cover in a hazardous area.

Password Menu Options
- Three programmable password selections can be used for the following: restrict modification of settings, prevent resetting the total or grand total without the password, or permanently lock out the ability to change or reset the grand total or any grand total related settings(making a non-resettable grand total).
- Pass: Restricts modifications of programmed settings to require re-entering the password to make changes.
- Pass T: Restricts the reset of total to require re-entering the password. Disables the manual mode reset contact.
- Pass GT: Restricts the reset of grand total to require re-entering the password. May enable a non-resettable grand total and permanent lockout of grand total-related settings with a specific password.
