Explosion-Proof Multiple Inputs

Explosion-Proof
Precision Digital manufactures a wide variety of explosion-proof indicators and controllers which can be powered via either loop or line power and carry all the major approvals, such as FM, CSA, ATEX and IECEx. These instruments will accept a wide range of inputs, such as 4-20 mA, strain gauge, pulse, thermocouple, RTD and Modbus and can be equipped with relays, 4-20 mA outputs and serial re-transmission. They all feature displays that can be easily read in various lighting conditions, from wide angles, and from considerable distances.

Explosion-Proof Multiple Inputs

  • 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.

  • The ProtEX-MAX PD8-6080 Super Snooper Modbus® scanner offers all the functionality of the ProVu PD6080 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is a multi-purpose display and controller capable of scanning up to 16 process variables and includes dual analog process inputs. The scanner can be programmed as a Modbus RTU master, slave, or snooper. It is the ideal display for Modbus multivariable transmitters or for existing Modbus networks with transmitters in need of a conveniently located display in a hazardous area. As a master, the PD8-6080 can read up to 16 Modbus registers on up to 16 Modbus devices and automatically alternate each of these process variables (PVs) on the dual-line display along with a unit and tag for each. In snooper mode, the scanner can read any Modbus variables being polled by a master, which allows you to easily add a display into an existing Modbus network. Powerful math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio. The PD8-6080 includes a 24 VDC power supply to drive the transmitter and can be equipped with up to four internal relays and two 4-20 mA outputs. It can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons.

  • The ProtEX-MAX PD8-6081 Super Snooper feet & inches Modbus® scanner offers all the functionality of the ProVu PD6081 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It displays level information on a specially designed feet & inches display, instead of the usual decimal format. It is the ideal display for hazardous areas with Modbus level or multivariable transmitters and is capable of scanning up to 16 process variables. Its unique feet & inches upper LED display can indicate up to 99 feet, 11 and 15/16 inches. The 6-digit lower display can indicate units, tags, or other variables such as volume, temperature, or density. The PD8-6081 also has dual analog inputs, for integrating traditional 4-20 mA or voltage inputs in the display scanning. The scanner can be setup as a Modbus master, slave, or snooper. Various math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio. The PD8-6081 includes a 24 VDC power supply to drive the transmitter and can be equipped with up to four internal relays and two 4-20 mA outputs. It can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons.

    Why you should buy:
  • The ProtEX-MAX PD8-150 offers all the functionality of the Vigilante II PD150 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It provides alarming and monitoring capabilities for all of your level, pressure, flow, and other process switches. These explosion-proof alarm annunciators are available in two models; the PD8-154 has four (4) inputs and the PD8-158 has eight (8) inputs. Each model accepts inputs from relays, float switches, digital outputs, and many other discrete (on/off) devices. They can be field programmed for all common ISA alarm sequences including first out indication and provide alarm signaling through front panel LEDs and a built in 85 dB horn. The silence, acknowledge, and reset functions can be operated without opening the housing by using the built-in SafeTouch® through-glass buttons. Custom printed message labels can be included with your order at no additional charge.
