PR Electronics 6185 series are loop powered isolators provide galvanic separation of analogue current signals. Designed to give a simple and efficient solution in applications with unproblematic transmission of current signals according to NAMUR. The 6185 isolator is powered by the measured signal and loads the loop with a maximum 1.8 Vdc. Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without distance between neighbouring units, up to 168 channels can be mounted per meter.

• DIN Rail mounting
• 1-channel version, stock-no. 796-6991
• 2-channel version, stock-no. 796-6916
• 4-channel version, stock-no. 796-6948

The 9203B universal transmitters are programmable via the PR 4501 detachable display module (238-0641). The 4501 module allows the programming of the vast array of input and output parameters easily and safely. Together with advanced functions including 2 point calibration, process simulation and diagnostics.
With a simple menu and explanatory text the 4501 is extremely straightforward to navigate. Functions are clearly depicted on the 4 line LCD display even in low light conditions. Line 1 shows the input signal, line 2 shows the units, and line 3 shows analogue output or tag number. Line 4 shows the communication and relay status. In addition the 4501 features password protection. Programming access can be blocked by assigning a password which is conveniently saved in the 9203B transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.
