modbus lcd display manufacturer

The Tek-LCD 7804B 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 Tek-LCD 7804B is available in two upper display line configurations: 5-digit decimal display and feet & inches display with a bar graph. The lower line is the same for both versions and consists of seven alphanumeric characters.

The Tek-LCD 7804B carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. Two features that really make the Tek-LCD 7804B stand out are its wide viewing angle display and SafeTouch® through-glass buttons. These buttons allow the Tek-LCD 7804B to be programmed and operated through the glass, thus eliminating the need to remove the cover in a hazardous area.
