Isolated Outputs, 4-20 mA Current Loops : MSXB 074
When you need a transmitter for 4-20 mA current loops
The MSXB 074 Isolated 4-20 mA Current Loop Output module provides isolated current outputs for DAP systems. Transmit signals on up to eight 4-20 mA current loops for real-time control of machinery or process equipment, or for automated test of sensors and process equipment. Each module is calibrated for current outputs.
MSXB 074 includes eight loop-powered current outputs, each with its own ground, isolated from the PC. The actual range is 0-24 mA, and this extended range lets you use the product to test any of your 4-20 mA circuits: 0 mA simulates an open circuit and 24 mA is 20% over the normal range.
Like other SI modules, MSXB 074 connects to a DAP board directly controlled by a PC or by a DAPserver. The DAP can send dynamic signals to the current outputs on the MSXB 074 SI module at an aggregate update rate as high as 1M updates/second.
Connect multiple Isolated 4-20 mA Current Loop Output modules to a single DAP board for high-channel-count systems.
For a complete current loop test system, add the Isolated 4-20 mA Input module MSXB 086.
MSXB 074 is usually installed in an Industrial Enclosure and uses a DB-37 connector. Other options are available.
