4104 Universal Uni-/Bipolar Signal Transmitter

From PR Electronics, the 4104 universal signal transmitter designed for measuring and outputting bipolar or unipolar voltage and current signals. The robust single channel transmitter features a wide range of freely programmable bipolar or unipolar inputs and outputs, therefore the 4104 is suitable for nearly any voltage or current conversion. Works with both passive and active inputs and outputs. The 4104 universal signal conditioner offers the flexibility to meet the many demands of today’s industrial applications. PR Electronics 4104 transmitter is designed according to strict safety requirements meeting the NAMUR NE21 recommendations, ensuring high accuracy in harsh EMC environments.

Features and Benefits

• Configurable bipolar or unipolar current and voltage inputs and outputs
• Universal AC or DC supply
• A green / red front LED indicates normal operation and malfunction
• 3-port 2.3 kVAC galvanic isolation
• Exceptional mA output load stability of < 0.001% of span/100 Ohm
• Very low power consumption means units can be mounted side by side without an air gap – even at 60°C ambient temperature.
• Approved for marine applications
• Complies with NAMUR 21 (burst), NE43 (sensor error), LVD and UL 508
• DIN Rail mounting

Programming

The 4104 universal transmitters are programmable via the PR 4501 detachable display module (7966890). 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 4104 transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.
