Overview
Analog Input Configuration
The Z7127 provides eight isolated input channels for monitoring analog signals. Each channel supports 4-20 mA current signals and 0-10 V voltage signals, making the module suitable for interfacing with compatible field transmitters and measurement devices.
For current inputs, the module has a 250 ohm input impedance. Its stated accuracy is +/-0.1% of full scale, which defines the specified measurement accuracy across the configured input range.
Power Supply and Electrical Characteristics
The module operates from a 24 VDC power supply with a +/-10% tolerance and has a maximum power consumption of 4.5 W. Meanwhile, the 1500 V AC isolation between channels helps limit electrical interference and unwanted signal coupling between input circuits.
