ADLINK DIN-812M Terminal Block Installation Manual

Basic Information

Product model: DIN-812M, Linghua dedicated 2-axis motion adapter terminal board

Hard compatibility limitation: Only compatible with PCI-8132 sports control card, prohibited from pairing with any other sports card

Core positioning: Designed specifically for Mitsubishi J2S servo/stepper motors, providing two sets of mutually exclusive wiring solutions, integrating limit origin IO, universal DI/DO, comparison trigger, encoder feedback, emergency stop switching functions, and supporting DIN rail industrial installation.

Overall hardware layout and connector classification

1. Purpose of core interface

Interface specification and function description

CN2 100 pin SCSI backend bus, one-to-one connection to PCI-8132 motion control card

CNA1/CNB1, CNA2/CNB2 20 pin 3M connector Mitsubishi J2S servo dedicated shaft interface (one set each for shaft 1 and shaft 2)

SJ1/SJ2 10 pin needle set stepper/third-party servo pulse interface (pulse+direction)

SJ3/SJ4 10 pin external encoder feedback channel

IOIF1~IOIF7 Mechanical IO/Universal DI/DO/Trigger limit, origin, deceleration, isolated digital input/output, position comparison COMP signal

HD1/HD2 6-pin backup servo auxiliary interface servo enable, ready, alarm, external emergency stop expansion

J1/J2/J3 jumper group emergency stop logic, DI common terminal level configuration

Real time display of external input level status such as limit and origin by the LED indicator light group IOIF

2. Key wiring taboos (mandatory rule)

The internal signals of CNA/CNB (Mitsubishi servo) and SJ (stepper) on the same axis are directly short circuited, and simultaneous wiring is prohibited, otherwise the short circuit will burn out the drive/control card; Choose one of the two wiring methods.

Mechanical specifications

Installation standard: DIN rail installation, with millimeter size engineering drawings attached

The overall length is 123mm, with connectors arranged on the entire panel and fixed installation holes reserved on both sides;

All signals are equipped with IGND isolation ground, isolated digital IO, and suppressed ground loop interference.

Description of supporting cables

Mitsubishi J2S servo needs to purchase Lingyuan factory 20 pin one-to-one dedicated cable; The sports card and terminal block use standard 100 pin SCSI cables.
