4-Channel Current Input Module

The BFKK 1734-IE4C is a POINT I/O analog input module designed for industrial control systems. It provides four single-ended, non-isolated current inputs suitable for process monitoring applications. This unit is intended for automation engineers integrating high-density signal acquisition into Rockwell Automation architectures.

Sustained Signal Integrity

The module maintains an input impedance of 60.0 Ohms across its operating range. A common mode rejection ratio of -120 dB suppresses noise during continuous operation. Input current terminals accept either 4-20 or 0-20 milliampere signals without isolation between channels. Performance remains stable under sustained load conditions.

DIN Rail Mounting Considerations

Installation uses the standard POINT I/O base for tool-less DIN rail mounting. The non-isolated inputs require careful wiring to avoid ground loops in multi-device systems. Builders who need channel-to-channel isolation or voltage input capability should select a different module type. Terminal block removal allows field wiring before module seating.

Questions about this item

How much heat does the 1734-IE4C module generate when running continuously in a POINT I/O chassis?

The module draws only 4-20 mA per channel with 60.0 Ohm input impedance, so self-heating is minimal inside an enclosed cabinet.

What POINT I/O base and backplane does the 1734-IE4C need to operate?

It mounts on any 1734 series terminal base and communicates over the POINT I/O backplane for power and data.

Will the 1734-IE4C share the backplane cleanly with older 1734 discrete I/O modules?

Yes, the 120 dB common-mode rejection and non-isolated current inputs prevent cross-talk on the shared POINT I/O bus.
