IMH40062 - 

The Apollo Intelligent Decade Volt and Current Meters accept a wide range of input signals and precisely scales them into engineering units. The IMD Volt Meter accepts inputs from ±2 VDC to ±300 VDC in one of four ranges. The IMD Current Meter accepts inputs from ±200 μA DC to ±2 A DC in one of five ranges. A full 6-digit display accommodates nearly any engineering units and holds large totalization values. State-of-the-art digital circuitry virtually eliminates errors due to drift. A full complement of option packages are available to fulfill many process applications. Both models feature a choice of two different scaling procedures which greatly simplify initial set-up. English Style display prompts and front panel buttons aid the operator through set-up and operation. A front panel lock-out menu protects set-up data and operation modes from unauthorized personnel. Programmable digital filtering enhances the stability of the reading. Programmable remote input “E1-CON" pin can be utilized to control a variety of functions, such as totalizing, alarm control, display hold or tare operations. All set-up data is stored in E2PROM, which will hold data for a minimum of 10 years without power. An optional integrator (totalizer)/linearizer can be used to totalize or integrate signals up to a maximum display value of 999,999. It features independent scaling and a low signal cut-out to suit a variety of signal integration applications. Additionally, nine slopes and offsets can easily be programmed with this option to linearize transducers with non-linear outputs, such as square law devices. Optional programmable remote input “E2-CON" pin can be utilized to control a variety of functions, such as totalizing, alarm control, display hold or tare operations, simultaneously with “E1-CON" pin. Peak/valley (max/min) reading memory, display hold and a signal re-zeroing (tare) function are included with this option and they are easily recalled and controlled by either the front panel or a remote switch. All readings are retained at power-down. Optional dual relays with parallel solid state outputs are fully programmable to operate in a wide variety of modes to suit many control or alarm applications. Optional 20 mA loop, bidirectional serial communications provides computer and printer interfacing to extend the capabilities of the indicator. More than one unit can be connected in the loop with other RLC products which have serial communications capabilities. An optional 4 to 20 mA or 0 to 10 VDC re-transmitted analog output can be scaled by the user to interface with a host of recorders, indicators and controllers. The indicator has several built-in diagnostic functions to alert operators of any malfunction. Extensive testing of noise interference mechanisms and full burn-in makes the indicator extremely reliable in industrial environments. The die-cast front bezel meets NEMA 4/IP65 requirements for washdown applications. Plug-in style terminal blocks simplify installation wiring and change-outs.
