ELECTRICAL PROFILE

Eight independent AC input paths

Each field point has its own input and neutral connection. Point-to-point isolation supports independent 120 VAC input circuits within the same module.

300 VAC
POINT-TO-POINT CONTINUOUS
 
INPUT CHARACTERISTICS

Defined switching thresholds

ON-state voltage 70–120 VAC ON-state current 5–15 mA
OFF-state voltage 0–20 VAC OFF-state current 0–2.5 mA
Typical input current 13 mA/point Maximum per point 15 mA
Input impedance 10 kΩ typical BIU current draw 40 mA max.
SIGNAL PROCESSING

From field contact to controller state

AC field state

A switch, relay contact or compatible AC device applies voltage to an input.

Threshold filtering

Resistor and capacitor networks establish switching thresholds and filter the input.

Optical isolation

Optoisolators separate field-input circuits from the module logic.

BIU transfer

Eight buffered states are converted into serial form and read by the Bus Interface Unit.

RESPONSE & ISOLATION

Timing suited to conventional AC devices

ON response 10 ms typical / 20 ms maximum
OFF response 20 ms typical / 40 ms maximum
Field input to logic 250 VAC continuous; 1500 VAC for 1 minute
Point to point 300 VAC continuous
LOCAL INDICATION

Status visible at the station

Eight circuit LEDs
Each LED represents the buffered ON/OFF state of one input.
PWR indicator
Illuminates when backplane power is present.
WHEN THE INPUT STATE MATTERS

Common operating and replacement situations

Typical system role

Used in GE Field Control stations to monitor 120 VAC limit switches, relay contacts, interlocks, permissives and machine-state circuits.

Why teams search for it

Search activity often follows a missing input transition, a channel that remains ON or OFF, mismatched circuit indication or loss of the PWR LED.

Downtime exposure

A lost permissive or interlock state can prevent startup, interrupt a sequence or hold equipment in a safe stopped condition.

INSTALLATION CHECK

Preserve the isolated input arrangement

Every input uses its corresponding neutral terminal. Verify the complete field circuit before transferring conductors.

01 · POWER
Use an external 120 VAC supply for the field input devices.
02 · TERMINALS
Keep each input paired with its corresponding neutral connection.
03 · SAFETY
Switch off field power before handling this high-voltage module.
04 · TEST
Compare field voltage, circuit LED state and the controller input bit.
BOX TERMINAL BLOCK
IC670CHS002 / 102
Separate input and neutral terminals for all eight channels.
BARRIER TERMINAL BLOCK
IC670CHS001 / 101
Can be paired with an auxiliary terminal block when more connection points are needed.
CONNECTOR TERMINAL BLOCK
IC670CHS003 / 103
Uses one 20-pin male connector for the installed module.
FIVE PRACTICAL QUESTIONS

IC670MDL233 FAQ

How many inputs does IC670MDL233 provide?
It provides eight isolated discrete inputs. The module transfers the channel states as one byte of input data.
What voltage turns an IC670MDL233 input ON?
The defined ON-state range is 70 to 120 VAC. The OFF-state range is 0 to 20 VAC.
Does IC670MDL233 need a separate field supply?
Yes. The Bus Interface Unit powers the module electronics, while an external 120 VAC supply powers the connected field devices.
Are the eight inputs isolated from one another?
Yes. Point-to-point isolation is rated at 300 VAC continuous. Each input has its own neutral connection.
What should be checked before replacing IC670MDL233?
Confirm the complete part number, terminal-block type, slot position, field voltage, input-to-neutral wiring and the controller bit assignment. Remove field power before handling the module.
