GE-FanucIC610MDL116BSeries One Analog Input Module, 4 Channel, 4–20 mA

Product Description

What this part is

A GE Fanuc Series One analog input module, IC610MDL116, with four 4–20 mA current input channels. It sits in a Series One rack and converts four analog process signals — pressure transmitters, flow meters, temperature transmitters, load cells, valve position feedback — into register values the Series One ladder program can compare, scale and act on.

It is an analog input module. The card carries analog input channels only, and it accepts current-output transmitters.

Decoding the order code

IC: GE Fanuc Automation industrial controls prefix.

610: the Series One PLC family. The GE Fanuc groups do not interchange — IC610 is Series One, IC600 is Series Six, IC630 is Series Three, IC693 is Series 90-30, IC697 is Series 90-70. A Series 90-30 equivalent such as IC693ALG221 does the same job on a different platform.

MDL: the Series One module class for I/O modules. Series One communications modules carry CCM and CPUs carry CPU, so the class letters tell you the tier of the card before you look anything up.

116: the specific module, here the 4-channel 4–20 mA analog input. Neighbouring MDL numbers are quite different cards — MDL110 is a high-speed counter, MDL152 is an output module, MDL101 is a discrete input.

B: the hardware revision letter. A revision suffix, not a different product.

What these specs mean in practice

4–20 mA is a current loop, and that is the whole point of it. Current signals hold accuracy over cable length where a low-level voltage signal degrades, and because the live zero sits at 4 mA rather than 0 mA, a broken wire reads as 0 mA and is distinguishable from a genuine bottom-of-range measurement.

Loop power arrangement matters. Two-wire transmitters take loop power from the supply; four-wire transmitters supply their own. The module reads current in either arrangement, and GEK-90477 carries the wiring detail.

This card takes current input. A 0–10 V or ±10 V transmitter suits a voltage module or a voltage-to-current converter.

Quantity and configuration

Sold as 1 piece — one 4-channel analog input module. New old stock, tested, in an opened box. Scope of supply is the module itself.

Interchange guidance

Searchable equivalents of the same part: IC610MDL116B, IC610MDL116, IC610-MDL-116-B, IC610 MDL 116 B, IC610MDL116-B. Other revision letters of IC610MDL116 are the same module at a different revision. Different Series One cards: IC610MDL110 (high-speed counter), IC610MDL152 (output module) and IC610MDL101 (discrete input). IC693ALG221 is the Series 90-30 4-point 4–20 mA analog input — the same function on a different platform and backplane, so it is a functional counterpart rather than a drop-in replacement.
