Description
The DRI-LPO Series are DIN rail mount, DC input, single or dual channel, isolating two-wire transmitters. Each channel accepts a DC voltage or current input and provides an isolated 4 to 20 mA output. Each channel is fully isolated (1800 Vdc) from input-to-output and channel-to-channel.

All DRI-LPO Series modules feature plug-in screw terminals for easy installation and low Mean-Time-To- Repair (MTTR). Two or more modules can slide together and interlock for solid, high density mounting. This is accomplished by removing either the foot, or the adjacent unit’s faceplate (for right-hand side or left-hand side mounting, respectively). The module to be attached will easily slide on to the side of the mounted unit.

DC input, two-wire transmitters are used to isolate and convert a DC voltage or current into a proportional 4 to 20 mA signal. Two-wire transmitters are primarily used in remote locations near the sensor since they reduce the probability of signal errors and save wiring costs by utilizing the two power wires to send the 4 to 20 mA signal. The current signal is usually monitored by a control system or displayed for an operator.
