PR Electronics 6185 Series Loop Powered Isolator, Current Input, Current Output

6185 type is a 1-, 2- or 4-channel galvanic isolation module. Inputs and outputs are floating and galvanically separated. Elimination of ground loops and measurement of floating signals. Especially useful in applications necessitating an unproblematic transmission of current signals according to NAMUR (sensor error detection).

Loop-powered isolator
1-channel version, stock-no. 796-6991
2-channel version, stock-no. 796-6916
4-channel version, stock-no. 796-6948
No separate supply necessary
Low response time
High noise suppression
Powered by the measured signal and loads the loop with max. 1.8 Vdc
Input is protected against overvoltage and polarity error
Drop voltage for each channel can be calculated according to the following expression: V_drop = 1.8 + (I_out * R_load) Output is voltage-limited to 15 Vdc
DIN rail mounting

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.
