Model C2464B Omniterm LPS Loop Splitter - 1

OMNITERM LPR & LPS LOOP REPEATER/SPLITTER Model C2463B LPR (Current Loop Repeater) & C2464B LPS (Current Loop Splitter). • Isolate 0/4-20mA loops • Create extra isolated 0/4-20mA signals • Create extra drive in an existing loop. • Very low volt drop/insertion resistance • 0-20mA or 4-20mA input • Voltage or current outputs • 24Vdc powered • Output current loops individually isolated. FEATURES • DIN Rail or surface mountable No Field Calibration necessary Narrow 22.5mm module width Wide operating temperature range High Accuracy 1500Vac Isolation Input/Output/Power Supply OVERVIEW The OMNITERM LPR current loop repeater and OMNITERM LPS current loop splitter products are specifically designed to create additional current loop signals from an existing current loop signal with minimal effect on the impedance of the existing loop. The LPR has a single isolated output while the LPS has two isolated outputs. These 24Vdc powered modules accept a 0-20mA or 4-20mA input, and create 0-20mA or 4-20mA outputs. The output current loops repeat the input signal and are isolated from the input signal and 24Vdc power supply. Impedance changes on the output loops have no effect on the input loop. The LPR has an internal 250 ohm precision resistor that can be connected to provide a convenient 1-5Volt output for connecting to a PLC’s etc. with voltage input. These second-generation products utilises advanced electronic techniques to achieve high accuracy with minimum loop losses and zero field calibration. Forming part of OMNIFLEX’s extensive OMNITERM range of industrial instrumentation, the OMNITERM LPR and LPS are designed to be DIN rail or surface mounted and are an economical 22.5mm wide.

Model C2464B Omniterm LPS Loop Splitter - 5

OMNITERM LPR & LPS LOOP REPEATER/SPLITTER Model C2463B LPR (Current Loop Repeater) & C2464B LPS (Current Loop Splitter). Application Notes Using the LPR or LPS to monitor SIL1 Safety Loops The LPR and LPS modules have been certified to SIL1 for the monitoring of safety loops. There is an increasing awareness today of the importance of safety in dangerous processes. IEC61508 is the most universally applied standard for the qualification of Safety Integrity in Safety Instrumented Systems. Individual control loops are usually certified to Safety Integrity Level 1 (SIL1) as specified in...
