PR Electronics 3100 Series Loop Powered Isolator, Current Input, Current Output, ATEX

3185 type is a 1 or 2 channel input loop powered isolator. Inputs and outputs are floating and galvanically separated. The converter eliminates ground loops and can be used for measuring floating signals. Also provides surge suppression and protects control systems from transients and noise.

Signal 1:1 functional range 0-23 mA
1-channel version, stock-no. 796-7102
2-channel version, stock-no. 796-7105
Low input voltage drop, typ 1.35 V + Vout
Powered by the analog input current signal loop
The output is voltage limited to 17.5 Vdc
Excellent conversion accuracy, better than 0.1% in the range 0-20.5 mA
High galvanic isolation of 2.5 kVac
Fast response time < 5 ms
Excellent signal/noise ratio > 60 dB
Can be mounted in Safe area or in Zone 2 and Cl. 1 Div 2. area
Slimline 6 mm housing
DIN rail mounting

Re-calibration is not needed after changing the DIP-switch range settings. Just change the DIP-switch, cycle the power to the unit and obtain the new, pre-calibrated I/O range. HART programming is enabled for selected devices.

Devices can be mounted both vertically and horizontally with no air gap separation required. The devices snap onto a power rail or DIN rail and are easily detached by lifting the bottom lock.

Safe galvanic isolation of 2.5 kVAC provides high noise immunity and prevents ground loops for accurate delivery of the process signal to your control system.

A front LED indicates device status, e.g. an error in the set-up, sensor or hardware.

All terminals can withstand up to ±31.2 VDC and are protected against incorrect supply wiring to ensure safe, error-free installation.
