How to Use Acromag 600T Series Isolated Transmitters – 8401028

Application 1

Re-transmitting a signal from a two-wire loop to a second location.

Solution

Use either a model 651T-0600 (single channel) or 652T-0600 (dual channel) transmitter.

Application 2

Splitting a signal from a two-wire loop: two outputs for different locations.

Solution

Use either a 653T-0600 (single input, dual output) or 652T-0600 (dual input, dual output) unit.

Application 3

Retransmitting a signal output from a controller or a D/A card.

Solution

Use either a model 671T-0600 (single channel) or 672T-0600 (dual channel) transmitter.

Application 4

Low-cost, channel-to-channel isolation of 4-20mA signals for controllers.

Solution

Use either a 652T-0600 (dual channel) for A/D cards or a 674T-0600 (quad channel) for D/A cards.

 

 

Application 5

Powering field transmitters (2-wire) and providing low-cost isolation of 4-20mA signals for controllers.

Solution

Model 652T-0600
Model 674T-0600
Model PS5R-SB24

Application 6

Require 4-wire isolators for input and output signals for controller. Built-in excitation supply needed for some field 2-wire devices.

Solution

Model 632T-0100 (dual channel, AC powered) or Model 632T-0500 (dual channel, DC powered). Model 631T for single channel 4-wire isolators.

Application 7

Require a 4-wire isolator “splitter” to excite a field device and re-transmit 4-20mA to two locations.

Solution

Model 633T-0100 (AC powered) or Model 633T-0500 (DC powered).

Use additional 633T units for re-transmitting to more locations. Install inputs in series with primary 4-20mA loop or the re-transmitted loops as required.

Application 8

Require 4-wire isolators to retransmit a 4-20mA signal to three locations.

Solution

Model 633T-0x00 (splitter) and Model 631T-0x00 (one channel isolator). (Where x = 1 or 5 for AC or DC power)
