3186 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.
Features and Benefits
1:1 output loop powered isolator of 2-wire transmitter Excellent accuracy 1-channel versions, stock-no. 796-7109 & 136-8709 2-channel version, stock-no. 796-7118 & 136-8710 Signal 1:1 functional range 3.5-23 mA Low input to output voltage drop typ. 2.5 V Fast response time < 5 ms Excellent signal/noise ratio > 60 dB Powered by the host loop voltage Wide supply range from 6-35 V High galvanic isolation of 2.5 kVac Can be mounted in Safe area or in Zone 2 and Cl. 1 Div 2. area Slimline 6 mm housing DIN rail mounting
DIP-switch programming
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.
Mounting
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.
High level of isolation
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.
Device status indicators
A front LED indicates device status, e.g. an error in the set-up, sensor or hardware.
Over voltage- / polarity protection
All terminals can withstand up to ±31.2 VDC and are protected against incorrect supply wiring to ensure safe, error-free installation.
