Loop Powered Indicators Provide On Site Local or Control Room Display of Critical Process Variables
The X54-201 utilizes low power circuitry, similar to the X54-200 and X54-202, but will drop less than 1 Vdc in the current loop. These units can be factory calibrated to the customer's specifications or field scaled by the customer. Linear or Square Root extracting displays, zero, full scale and decimal point location are all field set with internal jumpers, switches and potentiometers. Available housings include NEMA type 7 and 4 rated explosion-proof (for Class I, Division 1, Groups B, C, D and weatherproof installations) or general purpose panel mount units for control room applications. The panel mount version can also be combined with Ronan Annunciators, Lamp Cabinets and Process Monitors in hybrid configurations. The NEMA type 7 configuration has also been Factory Mutual approved as Intrinsically Safe when used with the appropriate IS Barrier.
