Model 8080MK Loop Powered Indicator with LED Display--International Metal Engineering

Introduction

IME Model 8080MK Loop Powered Digital Indicators allow the process variable from any 4-20mA current source to be monitored. Since the unit derives its power from the loop, no additional power supply or wiring is needed. Because of its low voltage drop (5.3 Volts at 20mA), it can be incorporated into almost any 2 wire loop, where local indication of a process variable is needed, because the integral transmitter indicator is inaccessible to view a different location.

Description

IME Model 8080MK Indicators are designed for use in process industries where vibration, inclement weather and corrosive atmospheres prevail. The electronics are enclosed in a copper-free epoxy coated Aluminum housing and for more aggressive environments, a SS316 housing is optionally available. The housings meet the requirements of NEMA 4X, and are certified Explosion Proof by FM and CSA.

LED Meter

The Model 8080MK has 4 digit display and may be configured to read -999 to 9999 with a 4-20mA input signal. The decimal point location and engineering units can be adjusted using membrane switches, eliminating all potentiometer measurements.

Mounting

IME Model 8080MK can be wall mounted or mounted on a 2" pipe using mounting brackets.
