Features:
- Provides one dedicated high-speed counter channel for a Series Three controller.
- Presents the accumulated count as four BCD digits with a separate sign output.
- Uses a 24-pin interface with twelve identified conductor pairs.
IC630MDL310 converts one high-speed count into units, tens, hundreds, and thousands groups that an external BCD device can read.
The 1, 2, 4, and 8 conductors for each digit must remain aligned with the A/B connector rows, while the sign line is handled separately.
External supply positive uses A10 through A12, common uses B9 through B12, and IC630MDL310A adds 200 mA to the rack's +5 V load.
The General Electric IC630MDL310 High Speed Counter Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the counter result is organized
- Dedicated resource: IC630MDL310A is listed as one high-speed counter rather than a bank of discrete input points.
- Decimal decades: The interface separates units, tens, hundreds, and thousands into four BCD groups.
- Weighted signals: Each decade uses 1, 2, 4, and 8 conductors so the receiving device can reconstruct a decimal digit.
- Sign state: A distinct sign output accompanies the four-digit value and must not be treated as another weighted bit.
Matching the decimal interface to the receiving device
- Four positions: Separate conductor groups represent units, tens, hundreds, and thousands.
- BCD weights: Signals marked 1, 2, 4, and 8 form each decimal digit at the external interface.
- Receiving logic: The connected indicator or controller must interpret the same active-state convention and digit order.
- Sign conductor: The dedicated sign output is routed independently from the weighted digit lines.
Preserving the 24-pin field interface
- Row orientation: The connector is divided into A and B rows with twelve numbered positions in each row.
- Positive supply: Positions A10 through A12 are allocated to the external-supply positive connection.
- Supply common: Positions B9 through B12 provide the documented external-supply common path.
- Cable identity: Twelve defined wire pairs should remain traceable so the BCD groups and supply conductors are not interchanged.
Accounting for the module in the Series Three power budget
- Load assignment: The GE table allocates twenty +5 V load units to the complete catalog number IC630MDL310A.
- Current equivalent: At 10 mA per unit, the published rack demand is 200 mA on the +5 V rail.
- +12 V rail: No +12 V load is entered for this high-speed counter module.
- Calculation basis: Series Three load values use the worst-case condition with all inputs and outputs active.
