THE DIR35 from Innovec Controls is a powered process indicator that accepts a 4-20mA, 0-10V dc or PT100 input signal, generates a 4.5 digit high intensity LED display of 14mm digit height, a 4-20mA retransmission output and two relays with changeover contacts rated at 3A 240VAC resistive.
All of the instruments functions are user programmable from the front of instrument mounted touch buttons which have tactile feedback. The functions include display brightness, decimal point, input scaling, 4-20mA output scaling and relay switch on, switch off points.
If you want to monitor tank level using a 2-wire pressure transmitter, the DIR35 has a regulated 24VDC loop power supply to energise the 2-wire tranmitter, simply scale the DIR35 in the level measurement units of your choice and its big bright display will do the job for you.
When using the instrument configured for a PT100 temperature input it will accept two or three wire sensors and display temperature in degrees C. It is powered from 120/240V ac or 18 to 36V dc. Electrical connection is by a two part plug together screw terminal.
