Digital Indicator with Control Option Series AF-70/AF-71/AF-72/AF-73/AF-74 (ASHE)

The Indicators accept all industrial standard input signals, like 4 to 20 mA DC, AC/DC Voltage, AC/DC Current, Resistance, Strain-gauge, Frequency and all temperature sensors like RTD Pt-100, Thermocouples, etc. The process value is displayed on a 4 digit seven-segment LED digital display. Up to four relay outputs are available as control options, each of which can switch a load of up to 10 Ampere rating.

The Digital Indicating Controllers are available in several dimensions in panel mounted execution and operate on AC or DC power supply, as required. Options include analog retransmission signals, Blind control option, DIN rail mount / weather-proof / flame-proof executions, Remote Control operation, etc.

All ASHE instruments carry a lifetime warranty against defects in components and workmanship.

Discription

The ASHE Series AF is a range of fully configurable microcontroller based universal Digital process Indicator with and without control relay outputs, offered in a highly compact, rugged and reliable execution. The instrument has three keys on the front panel, with which the operator can set the parameters and configure the instrument as desired. Single or Dual four-digit LED display options are offered on the front panel. The display can indicate any scale range between –999 to +9999 units.
