Hello can anyone give me wiring diagram to connect 3100 series rosemount transmitter with 751 type display and also to deltav control system. Thank you.
Which 3100 transmitter do you have, 3101,2,5,7,or 8?
In reply to Andi nurcahyo:
The 3101 is a simple 4-20mA 2 wire loop powered transmitter requiring 12 to 30Vdc. The 751 is a loop powered indicator not needing power. Do we know what the Delta V device is going to be, an analogue input card perhaps??? Does the Delta V i/p provide the loop power or will this be provided from an external source?
The wiring diagram for the 3144P is basically the same as the 3101, since they are both two-wire loop powered devices. So, the 3144P wiring convention can be used for the 3101 too.

Note: the 751 LCD does need a little power. There is a 1 V drop in the current loop. Separate power is not required. The AI CHARM provides 15 V, the transmitter needs 12 V, the indicator 1 V, this leaves 2 V margin for voltage drop along the wire. This means you can have a cable resistance up to 87 ohm. Using 0.75 mm2 or AWG#18 you can have more than 1 km of cable.
