4179 Universal AC / DC Transmitter
From PR Electronics, the 4179 universal AC / DC signal transmitter designed for measuring AC current and voltage signals and converting to a DC process signal. The 4179 is ideal for applications where there is a need for shunt and motor voltages or current for control and preventative maintenance, monitoring power lines, or a power supply. Featuring a built-in precision shunt resistor, the PR 4179 measures a maximum of 5A AC current, matching most current transformers on the market.
The 4179 universal signal conditioner offers the flexibility to meet the many demands of today’s industrial applications. The 4179 provides uni-/bipolar voltage or current outputs, and the current output can be active or passive. The wide selection of configurable output types makes it easy to connect to a wide variety of analogue input devices.
PR Electronics 4179 transmitter is designed according to strict safety requirements meeting the NAMUR NE21 recommendations, ensuring high accuracy in harsh EMC environments.
Features and Benefits

Programming
The 4179 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 4179 transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.
